In the previous paper, the structural anisotropy of concrete relative to the casting direction has been characterized by tensile tests and the effects of the internal defects shown by tensile anisotropy such as the fissures under aggregates or bleeding channels were discussed. In this paper, the effects of coarse aggregate size and content on the tensile anisotropy of concrete were investigated mainly. The outline of conclusions is shown in Fig.6 : (1) The larger the coarse aggregate size or content, the lower the tensile strength of concrete. (2) The extent of the reduction in strength of t_S, the tensile strength when the stress was applied in the same direction as casting, was more remarkable than that of t_R, the tensile strength when the stress was applied at right angles to the direction of casting. (3) So, the larger the coarse aggregate size or content, the more remarkable the tensile anisotropy, because t_S tends to be lower than t_R in usual concrete. (4) It is suggested that the defects under coarse aggregates affects the tensile strength more considerably than the bleeding channels do in usual concrete. (5) The tensile strength, especially when the tensile stress was applied in the same direction as casting, is possible to be a sensitive indicator of internal changes of concrete.

This paper deals with damages of structures subjected to severe earthquakes. Energy concept introduced by Housner has great advantages in simplicity and applicability to estimation of structural damages under earthquakes. Housner assumed that energy input contributable to structural damages can be expressed as [numerical formula] where E_D : energy input causing damages M : total mass of a structure y^._<e, max> : velocity response spectrum. However, the verification of the assumption has not been established yet. A general law on vibrational systems can be written as W_p+W_e+W_n=W_E, where W_E : total energy input exerted by an earthquake W_p : energy absorption due to plastic deformation of a structure W_n : energy absorption due to damping W_e : elastic vibrational energy. Structural damages correspond to W_p, and E_D may correspond to W_p+W_e. Through vast amount of numerical analyses on inelastic vibrational systems, each component of energy in the above equation was evaluated and it was found that Housner's assumption is basically accepted.

The efficient and practical system to analyse the dynamic nonlinear problems of rotational shells is developed. The system consists of the finite element and the mode superposition methods, and is effectively applied to solve the dynamic buckling of spherical shells under the simultaneous action of a uniform load and a concentrated force on the apex. The critical step loads reguired to produce snapping are numerically determined for shell parameterλfrom 10 to 18. The axisymmetrical snapping is found to be localized around the apex. The axisymmetric dynamic buckling loads, composed of a uniform lateral pressure and a concentrated force, being 2.42% of the total load, are compared with the static buckling loads obtained from the experiments by many authers and are revealed to be in exact agreement with the lower bound of the experiments. (Part 3) Asymmetric dynamic buckling loads of shallow caps with parameterλ=5, 6, 7 and 7.5 are numerically obtained. The asymmetric buckling is found to begin with the Mathieu typed oscillation between the symmetric and asymmetric deformations, however, the magnitude of the asymmetric displacements is too small to compare with the symmetric ones. The critical uniform step load, p/p_<cl>=0.40 in caseλ=7.5, gives a good agreement with the experimental results investigated by M.H. Lock et. al., which are ranging from p/p_<cl>=0.364 to 0.438.

The object of this paper is to establish the fundamental equations and there approximation in nonlinear theory of thin elastic shells under the Kirchhoff-Love hypotheses as a basis for analysis of elastic stability and large deflection. The derived nonlinear equilibrium equations for general-shaped shells allowing for the effect of deformation on equilibrium are given in terms of the stresses and displacements. Substituting the constitutive equations into the above equilibrium equations, our fundamental equations are obtained by the strain measures and related quantities for shell. Each terms in rigorous and complex those equations are estimated by the introduction of the concept of estimations about the order of magnitude for the important parameters (i.e. the membrane strain, the bending strain and the wave length in the shell region). The discussion of consistent and systematic approximations corresponding to the basic assumption of small strains from the exact fundamental equations of nonlinear shell theory are given under the above estimation.

This is the fourth report of the fundamental studies for the method of distribution of regional facilities. The summary of this report is following. 1. According to the results of the questionnaires, the users of regional facilities (shops, hospitals, elementary schools and children playlots) estimate the distance between those facilities and them as following. At distances within 300m, the users estimate the distance satisfactory, on the other hand, at distances over 1, 500m, they estimate the distance unsatisfactory. The relations between the satisfaction rate w(x) and the distance x are Fig.3〜5 and equation (1)〜(4). 2. The relations between the density of regional facilities m_2 and the total satisfaction rate (Z(m_2)=the number of users who estimate the distance satisfactory/the total number of users in regional area) are equation (12) and Fig.11〜14. As is obvious from these figures, the pattern of four graphs are similar to each other. But the total satisfaction rate in case that the distribution pattern of regional facilities is at random are 1〜25% lower than the total satisfaction rate in case of the distribution of equal distances (Fig.15). 3. In order to satisfy a certain satisfaction rate, the density of regional facilities in case of the random distribution are required from two times to four times as many as the density in case of the distribution of equal distances (Fig.16). This indicates that, when we decide the number of facilities in regional area, it is important how to distribute the regional facilities. In this case, a few relations mentioned in this report will be usefull.

Most lift caluculations are carried out when all other factors have been decided. However, these can not refer to detailed conditions of building shapes under consideration. It seems quite natural that computer with their inherent qualities of vast storage capacities and fast computation, should be applied to this paticular aspect of design. Computer can simulate lift traffic in model form. If data of lift performance can be surveyed, in simulation process, it would be able to quickly assess the lift planning of building. Most basic of the lift system for users; 1. A lift system must provide service for users within a reasonably short period of time. 2. The system must provide sufficient capacity of service to handle the maximum passenger load in the traffic pattern of peak period. From these aspects, the three important indices become; 1. The waiting time for a lift 2. The round trip time 3. The total number of passengers for a round trip Manual calculaton attachs great importance to the average round trip time, for a example, in Strakosh equation. However, in computer simulation, we can refer to the waiting time correctly. This simulation program was written to simulate the lift conditions existing in the traffic pattern of the maximum handling capacity in the evening. So the program can generate most alternatives of lift system (i.e. the standard system, the zoning system and the skip system), and simulate the conditions in each system. The flow chart is figured in Fig.1. The results obtained by simulations are transfered to caluculation tables (Table 4). These are consisted of two sorts of tables (or figure table) about unresponced time which is approximately equal to the waiting time. Planners are able to quickly evaluate both the lift system and the building shape under consideration according to these table. Generally, from the contents of the tables, the results observed are summarized as follows; 1. The lift speed in 20, 25 and 30 storey apartment building-at least faster than 60, 90 and 120m.p.m. each to serve as fast as the past lift system. 2. The average number of dwellings per lift-less than 75 units. 3. Among tree systems, the zoning and the skip system are recommended, and lift planning should take the qualities of each system into consideration. 4. The complexity of the traffic pattern is often a cause of bad services.

The architectural space concept is closely united with the fundamental space concept which lies at the root of human existence. So the definition of the architectural space concept is deeply depended on analysis of the fundamental space concept. The purpose of this paper is to present an introductive study of this fundamental space concept. In this part, I investigate about fundamental spatiality which has been already comprised in the phaenomenon of "Weltbild"-the conception of World. The world, as the unity of meanings, is organized and consisted of the cognition that is already estabrished. The cognition is estabrished by putting particuler experiences into spatial and temporal order. This demand (Das postulat) of spatial orientation is the spatiality as the epistemological foundation. In other hand, the concept of "world"-"Weltbild" is the "understood" world and it is changed by the substance of comprehension. This substance is the way of "understanding", and it is determined on historical situation (social and cnltural). This way of "understanding" is the foundation of "understanding world". It provides vacant epistemological foundation with concrete substance, and embodies the "Weltbild". The above is investigated on "Gestalt-Change" of "weltbild" which had happened bitween the Mediaeval and the Modern.

In Genzimonogatari, dem erdichteten Roman von Anfang 11 J.H., gibt es vielen Beschreibungen uber verschie lenen Ent-fernungsphanomenen, die bei Begegnung hinuber das im Wohnhaus (Shinden-zukuri) eingerichtete Entfernungsgerat geschehen sind. Die hier aufgenommenen Gerate sind diesem Roman gemass auf "Misu" (Bambussvorhang, die sich zwischen Sunoko (unbedeckte Beranda) und Hisasi (Moya umgegebene Zimmern) oder zwischen Hisasi und Moya (zentrales Zimmer) einrichtet) und "Kicho" (portabelem Wandschirm mit Tuch) beschrankt. Und noch hier trifft der Besucher, vor diesem Gerat sitzend, direkt die dahinter sitzende Einwohnerin oder sie durch ihre Vertreterinnen, die nur passiv jenen gut oder schlecht empfangt. Die Ent-fernung erscheint jenem wie folgend; das Gera verhindert seine Nahrung zu diese, trotz er in Modus der Potentialitat schon bei ihr ist. Dagegen vermisst diese die Moglichkeit jenes Eindringung in ihre Stelle durch dieses Gerat. So hangt die Ent-fernungs-phanomen an der Art des Gerates und der Stelle im Wohnhaus, wo sich es einrichtet. Damit verandert sich die raumlichen Seinsweisen der Beiden. 1. "Moto"-phanomen (Involvierung) bei "Kicho"; die Einwohnerin kann offen mit dem Besucher verkhren, nur wenn sie mit "Kicho" verdeckt ist. So wenn er gerade unten und neben dieses "Kicho" ("Moto" von "Kicho") eintreten darf. findet er sie fast direkt und vertraulich begegnen. Dies Sachverhalt heisst hier "Moto"-phanomen. Aber "Kicho" ist dinglich schwach, um seines Hineinsehen und Hineintreten in ihre Stelle zu schatzen. Dafur gibt es das traditionalle Schema; waas fur einen Mann den Platz vor "Kcho" nehmen darf. Unddamit wird moglich die offene Empfangsnahme der Einwohnerinnen. Das bedeutet also, dass es den Ort gibt, der das "Moto"-phanomen, die Involvierung von Hier und Dort unterstutzt. 2. "Mae"-phanomen (Vor) bei "Misu"; an "Misu" wird dieses Wohnhaus in Innen und Aussen geteilt. Wenn der Besucher ausser "Misu" sitzt, d.i. in Sunoko oder Hisasi, und noch sich nach Innen nahren will, findet er sich diese Stelle als negatives und unbequemes Hier, "Mae" von "Misu". Dabei erscheint eine bestimmte Struktur zwischen Hier und Dort, "Mae"-phanomen. 3. "Kage"-phanomen (Schatten) bei "Misu"; "Kage" bedeutet hier die Sphare, wo die Einwohnerin von anderen, insbesonders vom Blick der Manner, versteckt wird und zugleich mit "Misu"" als Ent-fernungsgerat geborgen ist. Sie ist also alle des versteckten Hier. Aber sie ist nicht homogen, weil es auffallige Verschiedenheit zwischen das Ende und die Tiefe dieses Orts gibt. Z.B. wird die Einwohnerin beurteilt roh oder fein je nach dieser Stellen. Und auch bei Begegnung danach ermisst der Besucher sie vertrautlich oder nicht. Diese von ihr genommenen Ent-fernung bedeutet dagegen die Moglichkeit, dass sie von ihm noch weiter in "Kage", versteckte und geborgene Sphare, entlaufen kann. Darum hangt diese "Kage" nicht nur an "Misu", sondern auch an das ganze Wohnhaus als das Ent-fernungsgerat. "Misu" zieht heraus die Bedeutung des Wohnungsorts. "Kage". 4. "Komori"-phaomen (Erschliessung im Wohnhaus); wenn man den Leichnam beruhrt, muss er sich im Haus einschliessen. Sonst wurde er sterben. Diese traditionalle Vorstellung bedeutet, dass die Einschliessung die Funktion hat, um wieder zu leben. "Ootono-gomori" (Einschliessung in das Schlafzimmer, d.i. Schlafen) hat auch gleiche Funktion. Der Ort von "Komori" entfernt sich also vom Tod. Es ist die wahre Bedeutung der Wohnungsorts, der die oben erwahnte verschiedene Phanomenen, die Beziehungen von Hier und Dort, unterstutzt.

The three Kumano shirines are Kumano-niimatsu Shrine (also called Hongu), Kumano-hayatama Shrine (also called Shingu) and Kumano-Nachi Shrine (also called Nachi). Of these shrines, "Hongu" contains the god, Ketsumiko, Hayatamashin is the god of Shingu and the Nachi waterfall is the god of the Nachi Shrine. The existence of the Hongu and Shingu Shrines is described in the records of the Nara Period. However, there is no mention of the Nachi Shrine. In my opinion there was probably a shrine at the foot of the waterfall. Ketsumiko was certainly the god of Hongu untill the middle of the tenth century, but it was not until the latter half of eleventh century that the god, Hayatamashin and the goddess, Musubishin were also enshrined in the Hongu. By the early half of the twelfth century the Shrines, "Goshogu", "Yonshogu", along with corridors, pagodas, the hall of the Buddha etc. were added within the sacred precincts. Hayatamashin was the god of "Shingu" untill the middle of the tenth century, but since then it seems that this shrine added the goddess, Musubishin, and the god, Ketsumiko along with others. As a result of this, this shrine was sacred to eight gods and a goddess by the early half of the twelfth century. In the early twelfth century "Nachi" Shrine was situated on the slopes of Mt. Nachi. This shrine also became as sacred a precinct as "Hong" and "Shingu". The two shrines, "Hongu" and "Shingu" acted in union until the middle of the eleventh century, but "Hongu", "Shingu" and "Nachi" had united their administrations by the latter of the twelfth century. Contents of this thesis are as follows : I. The Condition of the Three Kumano Shrines as Described in the Records of the Nara And the Early Half of the Heian Periods. II. The Condition of the Three Kumano Shrines as Described in the Records of the Middle And Latter Half of the Heian Period. II-1. The Condition of the Kumano-niimasu Shrine (Hongu). II-2. The Condition of the Kumano-hayatama Shrine (Shingu). II-3. The Condition of the Kumano-nachi Shrine (Nachi). III. Conclusion.
