This paper aims to establish the analytical method by which the elasto-plastic behaivours of multistory rein forced concrete structures with cantilever shear walls are obtained clearly. For this purpose, these structures are idealized to the resultant model composed of cantilever shear walls, adjacent elements connected to the shear walls, and frame elements, as shown in Fig.1.1. And elasto-plastic deformation characteristics of each resisting elements in structures are provided, as previous studies are reflected adequately on such characteristics. The trinominal expressions (Eq. 16.1-16.4) are derived in consideration of such characteristics. Then, the elasto-plastic behaivours of multistory structures with cantilever shear walls are obtained analyticaly by these equations. This analytical method is an incremental elasto-plastic analytical method.

Steel fiber additions to concrete make it achieve improvement in a lot of the mechanical properties of the material such as flexural strength, fracture toughness, impact resistance and fatigue resistance. This paper describes low-cycle fatigue tests on reinforced concrete columns with steel fiber reinforcement (SFRC) and without it (RC), and the experimental results which have been conducted on these two kinds of columns, i. e., the modes of collapse, restoring force characteristics, experimental equations of stiffness deterioration, Δδ-N_f curve, hysteresis absorbed energy and cumulative fatigue damage, etc. of SFRC and RC columns have been compared. This experimental study gives the fundamental data for evaluating earthquake responses of SFRC and RC structures and for comparing the damage of two structures. From the results of the study reported in this work, the following conclusions have been obtained. (1) The collapse mode of SFRC columns is flexural failure type. On the other hand, that of RC columns is shear compression failure type at the head or the knee of the columns. Both of SFRC and RC columns finally collapsed due to buckling of compressive longitudinal reinforcing bars. (2) Degradation for equivalent linear stiffness of SFRC columns is smaller than that of RC columns. Exponent a of degradation for equivalent linear stiffness of SFRC and RC columns vs. total displacement amplitude Δδ_r can be shown in the form of Eq. (2) and Eq. (3), respectively. (3) The capacity of energy absorption of SFRC columns is greater than that of RC columns under cyclic loading as shown in Fig.23. (4) The Δδ-N_f curve of SFRC and RC columns can be shown in the form of Eq. (4) and Eq. (7), respectively, as shown in Fig.15. The ΔE (average area of hysteresis loops)-N_f curve of SFRC columns is in the upper domain of that of RC columns in the ΔE-N_f plane as shown in Fig.17. (5) In case that the damage factor is evaluated by cumulative hysteresis absorbed energy, the tendancy in increasing of the damage factor of SFRC columns is closer to that of the n/N_f curve than that of RC columns, as shown in Fig.24. (6) The damage of SFRC and RC columns under cyclic loading in the domain of the large displacement shoud be expressed as the sum of the damage due to the maximum displacement and the damage of low-cycle fatigue. (7) The cumulative fatigue damage of SFRC and RC columns can be expressed in the form of Eq. (25), Eq. (26), and Eq. (27), respectively.

In order to evaluate the reliable earthquake response characteristics of structural systems, it is required to investigate the correspondence between the irregular geological properties of transmission path and the unspecified faulting process of source region and such important physical quantities as peak ground motions, spectral characteristics, duration times and so forth. In this paper, the idealized earthquake ground motion models represened by convolution of the average Green's function of a random medium and the random dislocation time function are analyzed to obtain some indication of the influence these factors may have on aseismic design of structural systems. The vertical, radial and cross-radial components of random earthquake time histories are calculated for Mach numbers M_n=0.6, 0.7, 0.8 and 0.9, rise time t_r=0.03 and the ratios of epicentral distance to focal depth R/H=1 and 5. The observation points of vertical and radial components are assumed to be in the direction of acceleration and deceleration of the fault rupture. The peak ground motions and duration times of vertical and radial components show significant variation with up-and down-Doppler effect associated with the fault movement. They become large and short when the fault propagates toward the observation points of vertical and radial components. On the contrary, they become small and long when the fault propagates in the opposite direction for the observation points. The peak ground motions and duration times of cross-radial component of the earthquake models in the perpendicular direction of the fault movement is insensitive to the variation of Mach number. Then, there is a strong dependence of peak ground motions and duration times at the site in the near field on the rupture direction of dislocation and the relative position between the focus of an earthquake and the observation point. There being some differences in the propagation velocities of P, SP, SV and Rayleigh wave motions, the duration times of earthquake ground motions become inevitably long with the increase of propagation distance unless the fault rupture occurs in the finite source region. The wave form functions, maximum values and their generation times of the earthquake models vary with the ratio of epicentral distance to focal depth since the energies of SV wave motions are transformed into those of SP and Rayleigh wave motions with the increase of the ratio. On the other hand, the wave form functions of cross-radial component of the earthquake models are varied a little with the ratio because there is no such energy transformation for SH wave motion of the component. Since the peak accelerations of random earthquake ground motion models become less sensitive to Mach number with the increase of propagation distance, the stochastic characteristics of them tend to be gradually stationary as the seismic wave motion propagates into the far-field. From the above discussion, it is concluded that Mach number, the ratio of epicentral distance to focal depth and the relative position between the causative fault and the observation point are important parameter and physical quantities for aseismic design of structural systems, which would describe the maximum values, frequency characteristics and duration times of earthquake ground motion.

An experimental study for the improvement of strong motion seismometry has been continuing, starting from the recognition that most of the ready-made accelerographs, such as the SMAC type accelerograph widely spread in Japan, have been becoming insufficient for responding higher demands from current study of earthquake engineering. In this paper, a new method is described for examining the performance of a strong motion seismograph as a means to disclose inadequacy of the conventional accelerographs as well as to explore ideal specifications to be installed in a forth-coming seismograph. Following this method, we can discuss the analyzable range in terms of period and amplitude of the records by a given instrument, namely, the observation capacity in view of signal to noise ratio of the records. As a result of performing this analysis in taking account of general characteristics of seismic motions, it has been demonstrated that the amplitude coverage of the SMAC type accelerograph is insufficient in the period range over 1 sec and it is principally caused by its conservative recording system with a very limited coverage of, say, 40 db at most. The amplitude range of ideal instruments should be extended, if possible, over 80 db for better and minute analysis by introducing digital recording system. In addition, lacking of absolute or common time recordings is pointed out as reason why SMAC records are far less than satisfactory in earthquake engineering. For increasing the time accuracy a high sensitive crystal clock should be loaded in the instrument. Along this line of consideration, two different types of instruments with much wider amplitude-and-frequency range than those under operation are proposed in the following paper.

In the seismic design of buildings affected by torsion, and advanced proposition was made in the recently revised national building code that the strength of each story of building should be enhanced according to the extent of torsional component of vibration. The provision may be deemed to be a measure which enables to reduce the increase of damage due to torsional effect. The amplification factor for the required strength was designated by the Fe-value. However, the physical meaning of the Fe-value is still obscure. The authors have tried to estimate the effect of torsion on the damage distribution of the structure through inelastic response analyses on buildings affected by torsion. Based on the result of analyses, a parallel expression of the Fe-value is proposed.

One of the typical steel column bases is formed by cladding column bases with reinforced concrete stubs. Based on a series of experiments on this type of column bases, an empirical formula for load carrying capacity is derived and their deformation characteristics are made clear. Steel columns have H-shaped cross sections and are applied axial forces and strong-axis bending. It is shown that the column bases can develop preferable behavior when an adequate disposition of reinforcing bars and anchor bolts is secured.

Although the provision of a safe escape route is the main process in evacuation system, it is not sufficient to guarantee hazard-free egress. The escape route should be well recognized by oucupants and enable them to reach locations of safty easily in the case of a fire. Standing on this viewpoint, the objective of the current study is to seize the tendency of escape direction of occupants. In a laboratory, subjects viewed pairs of slide projections and for each pairs they were asked which direction they would chose if they were involved in the case of a fire. Through analysys of responses to pairs of slide projections by the method of Thurstone's unidimensional and Nishisato's multidimensional scaling, the test has disclosed that visibility is the main factor of escape direction.

We descrived the use of computerized layout model as design aids in developing alternative layout designs. Input data to the model are the following : 1) shape and size of each rectangle room. 2) types of room, movable, fixed, semimovable x, semimovable y and movable within a territory, and bar type comonent. 3) association chart of c_<ij> which denotes communication frequency between room i and j. Rooms are located adjacently by heuristic methoh so as to minimize the total of the product of c_<ij> and the Euclidian distance d_<ij>, taking into account of the site. The total force on room i in the x and y direction is given by the equations, [numerical formula] where [numerical formula] U_R is the magnitude of the repulsion force between the two rooms whose frequency of communication is 0. R_R is a constant ratio of a tension and a repulsion force. M is a number of rooms total (fixed, movable, and semimovable). L is a number of components. Following formulas present the mathematical concept of forced directed location of moveable rooms. Try to find location to these equations by the method of successive approximation. U_v is a constant to move every room qradually. [numerical formula][numerical formula] The location procedure is broken down into three phases "forced directed location phase", "room overlap resolution phase" and "convergence phase". All boundaries between rooms being regarded as potential paths are considered a circulation path network for this layout. A vertex of a room is considered a node of the network. Find paths of minimum total length between every two given rooms by the Dijkstra Method. These paths construct the path communicating every room. Rooms along the path are moved to give the dimension to the path.

A large transfiguration occurred in the family succession process in the rural areas, after the so called rapid growth period of the Japanese economy. In Kutsuki village, Shiga Prefecture, more than 70% of the heads of families are older than 45, and among these families, more than 40% of successors had moved out. The average of moved out successors shows a tendency to be higher in the small hamlets of the mountain areas, and among the low propertied class families. According to the intention to come back and return age, four types were pointed out. Among these peoples, about 15% are planning to return while young, and to assure employments to them is important to accelerate this tendency.

The creation of the pteron was not only the establishment of articulation but also the creation of external appearance of the temple. By this, the temple had become the "object able to be seen" in the fields. The subsequent evolution of the Greek temple was realized through the refinement on its appearance, and the fact played an essential part in the design of the temple during the classic period. It is Doxiadis who points out that the planning of the Greek sanctuary which looks clattered at first sight is strictly arranged with the greatest circumspection by means of the polar coordinate, is systemicly equivalent to the visual perception of the form. That is to say, our field of view takes a spherieal shape which makes the apparent size of the object in it proportionate to the visual angle. The awakening of such vision in Greece is also found in the description of the Greek myth. According to the analysis of the implication of Greek verbs "see" that mean to in the myth, it is ascertained that the vision had developed from the metaphorical way of seeing in which the seen parts were merely associated to each other and resulted in the metonymical perception in which they were integrated into the whole. That is also recognized in our own development of the vision. Piaget investigated the fomative process of a child's vision, and clarified that the vision begins with the stage of topological space-grasping which grasps the form only based on the homeomorphic quality of the figure and develops into the stage of the projective spacegrasping which precisely grasps the interrelation of plural figures from the specific viewpoint through accurate grasping of a single figure. It is the function of the association that identifies different figures based on their homeomorphic qualities. Accordingly, as the topological space-grasping is due to the metaphorical vision, the precise grasp of the figure becomes possible with the metonymical vision. Therefore, the single-row-column temple which only constituted the naos regardless of the appearance, was founded on the metaphorical vision of the creation of the meaningful topos, and because the establishment of the peripteros stlye was based on the metonymical vision, then the space-grasp by means of the polar-coordinate system is evidently nothing but the projective space. Piaget further clarified the formative process of the Cartesian perspective space that trancends the projective space which pertains to the specific view point, through so-called decentralization which simultaneously adopts different view points and thus makes all of them relative to one another. This clarification could explain the conversion of the polar coordinate system to the Cartesian coordinate in the Greek site planning by Hippodamos in the 5th century B. C., and it also explains the development of the metonymical vision that lies in the background of the conversion.

Le slogan "une noble simplicite et une grandeur tranquille (eine edle Einfalt und eine stille Groβe)", que Winckelmann a proclame sur l'art grec, trouve en effet sa racine dans la litterature classique en France au 17^e siecle. Deja, dans la premiere moitie du 18^e siecle, c'est-a-dire, avant l'apparition de l'ouvrage de Winckelmann, le terme de "noble simplicite" etait souvent employe dans les livres d'architecture, par exemple, dans les ecrits de Boffrand, Briseux et Blondel, etc. Le concept de "la noble simplicite" est profondement lie a celui de "la nature" propre a l'age classique. Laugier soutenait qu'on devait imiter les procedes de la nature dans sa simplicite. Si l'on meditait une telle affirmation, on pourrait supposer l'equation : naturel=simple=classique, dans les arts et la litterature, a l'instar de la pensee de La Bruyere. Or, peut-etre seul, Quatremere de Quincy, dernier defenseur du style classique, a analyse ces concepts, la simplicite et la noblesse, plus en details que les autres theoriciens en Architecture a l'age classique. Selon lui, la simplicite exige la mesure bien menagee, et elle doit primer dans la conception, l'effet et l'execution des ouvrages architecturaux, quant a la noblesse, elle contient les quatre qualites, "la grandeur, la simplicite, l'elegance et la richesse." De la, on peut conclure que le concept de "la noble simplicite" exprime la balance entre l'element artistique et social a l'age classique, et que "la noble simplicite" est largement empreint du classicisme francais.
