ジャーナル フリーWe expressed the general fracture criterion which has been proposed in Part I for quasi-ductile fracture type in the form of the first order of σ_3, σ_<eq> and σ_m as following. U=a+bσ_3+cσ_<eq>+dσ_m……(1) √<U>=a′+b′σ_3+c′σ_<eq>+d′σ_m……(2) where U=elastic shear strain energy. Equation (1) is the fracture criterion represented by the elastic shear strain energy, and equation (2) is the fracture criterion represented by the general shear stress. Modiffied Griffith criterion was here adopted for the local fracture criterion by reason of simplicity The fracture criterion for tri-axial compressive stress states was gained as following. 1/3{(σ_1-σ_2)^2+(σ_1-σ_3)^2+(σ_2-σ_3)^2}=a+bσ_1+cσ_3+d(σ_1+σ_2+σ_3)/3……(3) √<1/3{(σ_1-σ_2)^2+(σ_1-σ_3)^2+(σ_2-σ_3)^2}>=a′+b′σ_1+c′σ_3+d′(σ_1+σ_2+σ_3)/3……(4) Eq. (3), (4) were too represented in x-y-m coordinate given by x=(σ_1+σ_2+σ_3)/3, y=√<2J′_2> and m=Lode's parameter, as following. y^2=a+(b+c+d)x+(3(b-c)-m(b+c))/(√<b(3+m^2)>)y……(5) [numerical formula]……(6) These equation well agreed with the all most experimental results in tri-axial and bi-axial compressive stress states. Finaly, the fracture surfaces was illustrated from the fracture criterion proposed in Part I and Part II.抄録全体を表示PDF形式でダウンロード (995K) -

ジャーナル フリーThe ground that supports the structures is generally composed of complex soil structures, such as a fluid saturated soil layer, a pile reinforced ground, a laminated soil medium and a granular medium. It is of necessity to express real soil structures as the ground in detail in order to understand the presice ground behavior under strong earthquake motions. In this paper, such a complex ground is assumed to consist of two phase medium, for which the mixture theory is applied. The ground is idealized as two mono-phase medium which the ground composed and coupling phase between them by the mixture theory. It simply describes the complexity of the ground structure, interaction of two phase medium and micro-macro behavior, compared with earlier previous theories.抄録全体を表示PDF形式でダウンロード (1607K) -

ジャーナル フリーThis is a subsequent paper to the previous paper published in the transactions of A. I. J. No.229. This paper deals with static tests on twelve specimens subjected to bi-axial bending moments and the analysis of the test results. Six specimens with 10 cm square cross section and six specimens with 15 cm square cross section were tested under the loading condition of constant bending moment about one axis and reversed cyclic bending moment about the other axis with constant deformation amplitude. As the results of the experiments, relationships among bending moments about two axes and flexural deformations about two axes were obtained. It is found that the relationships between bending moment and flexural deformation become stable during cyclic loading when both constant bending moment about one axis and constant deformation amplitude are small. In the analysis of this paper, only the range of monotonic loading is considered. Analytical and experimental results coincide well.抄録全体を表示PDF形式でダウンロード (809K) -

ジャーナル フリーThis report describes the experimentally obtained torsional behaviour of steel tubes under bending and constant compression. Testing machine is the one explained in "Part 1" only with the additional bending applicator. The bending capacity is 10 t-m and the rotation capacity is ±15°, limited by oil spherical fixture. End condition is that one end of a specimen is pin supported for bending and loaded with torsion, and the other is loaded with bending. Therefore the additional moment due to axial force is small. Test results are as follows. (1) Ultimate load carrying capacity could also be decided according to the interaction curve of compression and bending moment, modifying the yield normal stress taking shear flow under torsion into account. (2) The maximum load was maintained until local buckling occured, hence specimens showed elastic-plastic torsional behaviour. (3) Deformation capacity (√<(υ/υ_p)^2+(β/β_p)^2>) decresed when bending moment was superior to torsion. Finally, torsional and bending behaviour of closed sections is compared with that of wide-flange sections.抄録全体を表示PDF形式でダウンロード (878K) -

ジャーナル フリーThis paper describes as to fundamental theoretical study on the method of conversion of restoring force characteristics into an equivalent model. First, in a general nonlinear hysteretic force-deflection relation, the relation between vibrational characteristics (damping capacity and natural frequency) and geometric shape of the hysteresis curves are investigated. Next, the geometrical conditions for equivalent restoring force model in which have naturally vibrational characteristics for the hysteresis systems are considered. From these results, it is found that natural frequency of the hysteresis systems are determined by the total amount of ascending and decending branch of the hysteresis loops. This fact shows to equal the potential energy with hysteresis curves that natural frequencies are the same each other. The other side, damping capacity of the hysteresis systems is closely related to the energy dissipated in a single cycle, that is to say geometrically, to the area surrunded by the hysteresis curves. From the facts discribed above, we may determine the geometrical conditions for a equivalent restoring force model.抄録全体を表示PDF形式でダウンロード (1306K) -

ジャーナル フリーThis paper develops a new analytical technique to estimate stationary random response of the lumped mass structural system with such hysteretic characteristics as bi-linear, tri-linear ones. This technique utilizes some original idea about bi-linear hysteretic characteristics which suggests that this characteristics are expressed by two spring elements, one attached directly to the relative coordinates and the other indirectly to it through the coulomb slider. It is concluded that this new technique should sufficiently be available for the stationary or non-stationary stochastic earthquake response analysis of the hysteretic structural system by the fact that two results by this technique and the simulation one associated with transient displacement, velocity and shearing force responses showed fairly good agreement with each other for the cases of pseudo-stationary white noise excitations and one mass system with bi-linear hysteretic characteristecs. By making use of this technique, fundamental stationary random response characteristics are investigated from aseismic design point of view.抄録全体を表示PDF形式でダウンロード (865K) -

ジャーナル フリーThe most obvious effect of earthquakes on the majority of building structures is exerted by the short-period ground shaking. Among factors exerting influence on short-period ground shaking, the source mechanism of the fault seems to be very important problem. But this problem is remaining unsolved yet. Recent fault studies show that a relatively simple elastic dislocation model of faulting can explain the long-period (longer than several seconds) portion of observed seismograms. So far as the simple dislocation model of faulting is adopted, however, it is very difficult to explain the short-period (shorter than several periods) portion of them.抄録全体を表示PDF形式でダウンロード (868K) -

ジャーナル フリーThe main purpose of this study is to investigate the dynamic characteristics of cantilever-type concrete shell roofs. Three types of roofs are considered. They are conoidal shells, cylindrical shells and plane plates, which have the same plan and dimensions. Free vibrations and elastic dynamic responses of these shells and plates are analyzed by the finite element method and the behaviors of these shells are compared with one another. The effects of rises and thicknesses of shells are considered. The maximum displacements and stresses of shells in the dynamic response analysis are compared with those in the static analysis. As the results of this study, it is found that conoidal shells have some structural superiority to cylindrical shells and plane plates, as far as cantilever-type shells are concerned.抄録全体を表示PDF形式でダウンロード (945K) -

ジャーナル フリーIn order to protect our towns and cities from the fire caused by the earthquakes, it is necessary to study on the outbreak of fires. Many data were obtained on the outbreak of fires and the damage of dwelling houses caused by the earthquakes since Kanto-Dai-Shinsai in 1923. At first, stoves, ovens and other fire-tools which are the cause of outbreak of fires are classified and shown on the Table 3.2. Secondarily the relationship between the ratio of the outbreak of fires and that of the totally destroyed dwelling houses is examined. In this relationship, the difference of the outbreak of fires due to the season and the time when earthquakes occured are considered. In this study, the ratio of totally destroyed dwelling houses is used as the index of the intensity of earthquake motion. The foregoing relationship is the empirical formula on the ratio of outbreak of fires. The numbers of outbreak of fires caused by earthquakes can be predicted by this formula. The contents of this papers are as follows; §1. Introduction. §2. Method of Study. §3. On the outbreak of fires caused by earthquakes. §4. The relationship between the ratio of the outbreak of fires and that of totaly destroyed dwelling houses caused by earthquakes. §5. Summary.抄録全体を表示PDF形式でダウンロード (1285K) -

ジャーナル フリーContinued from the preceding papers (the same title, Part I, Part II), several wind tunnel experiments were made to investigate the behaviour of airflow around the building models standing on the flat plate. As a result, following remarks may be made. 1) The area where mean wind velocity is accelerated as compared with the case without models [the area of U^^-/U^^-_s<110(%)] increases as models become higher, and about one model, the area increases as the measuring plane (z) is higher (Fig. 6〜Fig. 13). 2) Airstream that flows over the models is comparatively small in quantity. 3) In the separation area, wind profiles are nearly conform to the log-law in cace the model height is low (Model 1, 5), but around tall models (Model 2, 3, 4), they are not necessarily conform to the law. 4) As to model depth (D), D has an effect on the wind velocity ratio (U^^-/U^^-_s) measured near the ground level, that is, U^^-/U^^-_s decreases as the model depth becomes smaller. 5) Air streams go down to the ground level before the models (down stream) and a small part of them flow upstream. In case a small model exists in front of the tall model, the velocity of that upstream flow increases and airflow rotates in the space between two models.抄録全体を表示PDF形式でダウンロード (774K) -

ジャーナル フリーIn the preceding report (Part 1), the concept of a subsystemt and its spatial domain was interpreted. In this paper the aushor analyzed the relation between boundary and location of subsystems compornents, and established the general rules for interface of subsystems. Three types of interface rules are suggested. (1) the inviolable interface (2) expression of the maximum deviation (dM) (3) expression of the range of deviation (dR) As a factor which govern the interface rules, much stress is put on the sequence of subsystem construction. In the case (2), the subsystem executed later must fill up the gap, invading the interface, while the components of the formerly executed subsystem are not allowed to invade the boundary. This rule is proposed for the first time here, against the existing theory of modular co-ordination.抄録全体を表示PDF形式でダウンロード (861K) -

ジャーナル フリーIt is important to approach scientifically the dwelling needs of occupants in order to establish laws concerning dwelling space. The dwelling needs cannot be simply listed, but must be ranked in order of their priority. In addition of the dwelling space needs of occupants requires knowledge of not only the priority ranking but of the relationship between various living needs and dwelling needs. Such inquiries require the construction of an analytical model which can guide empirical research into daily life and assist in ordering the various living and dwelling needs. An examination of studies relating to housing in different disciplines led the researcher to believe that the theory of life structure in Japanese branches of sociology and economics could be employed as a theoretical framework for the research. The theory of life structure, however, is currently subject to different interpretations according to each researcher, e. g. the parameters of its research have not been agreed upon. Therefore, this research sets fourth its own conceptualization of life structure after organizing existing contentions on the subject. An analytical model was constructed involving the approaches of the researcher as to what the main constituents of life, the parameters of life and so forth. This analytical model has six analytical axes : 1) distribution of time; 2) structure of dwelling space; 3) living expenses; 4) working conditions; 5) family relations; and 6) possession of durable goods. The model suggested many clues to guide the empirical research.抄録全体を表示PDF形式でダウンロード (1263K) -

ジャーナル フリーSucceeding the study as introduced in the last report, this research shows the details of structure of community, centering round direct communication, the medium which unites individuals into an collective body. Two channels of communication can be noticed in regional groups in urban areas : one is through the channel of neighbourhood; the other through certain indirect communication media. The former has the more of the nature of community communication which remains unliquidated in the process of urbanization; and the latter is a uniquely urban phenomenon. These two are quite incompatible with each other; and the original idea of community carries the former way of communication. However, this original community communication channel of neighbourhood has possibilities of rebirth through collective movements even within a region where neighbourhood channel is no longer available, for the inevitable regionality of the movements reclaims the channel of neighbourhood in a specific scope within which efficient operation of communication channel can be obtained. The communication channel through indirect media, however, no longer limits its sphere within regional bounds, but takes care of city-sized or intercitysized communication. Thus, as revealed in this research, each of these two natures of human unity in urban areas is unique in its size or its pattern of relation of dwellers, and uniquely determines the material and external features, for instance, the structural features of its public institutions which the dwellers demand, such as assembly halls.抄録全体を表示PDF形式でダウンロード (1443K) -
