ジャーナル フリーThe object of this paper is to clarify the relation of the tactile hardness of building materials to the physical one. The tactile hardness values were determined by the paired comparison method. The physical hardness values were obtained by A HARDNESS TESTER, newly developed. Good correlations between them can be obtained by the equation below; Z_j=1.44logP/δ-1.63 where Z_j : Tactile hardness value P/δ : Physical hardness value [kg/mm]抄録全体を表示PDF形式でダウンロード (1015K) -

ジャーナル フリーThe main purpose of this paper is to relate the scale of the sense on Hardness to the physical value of a building floor. The result are as follows. 1. We could relate the scale of the sense on Hardness to the deflection energy, being obtained from the static load-deflection curves of model floors. 2. We could obtain the equation for estimating the Hardness of a building floor using the deflection energy. 3. We could indicate the most suitable physical value of Hardness of a building floor.抄録全体を表示PDF形式でダウンロード (1015K) -

ジャーナル フリーThis report describes the experimental results of the torsional behaviour of steel tubes subjected to torsion and constant compression. Torsion is applied by rotating the oil spherical pinfixture. The capacity of the fixture is 200t. (max. stroke : 600mm) in compression and 100tm (max. torsional angle : 30°) in torsion. The specimens are annular sections (165.2φ), rolled square box Sections (175×175) and built-up square box sections (200×200). Test results are as follows. (1) Torsional deformation of rolled tubes showed perfectly elastic-plastic behaviour as τ-γ relation of the material of the specimens. (2) Shear flow under torsion was uniform not only in elastic range but also in plastic range. (3) Built-up tubes showed inelastic behaviour below yield load due to the incomplete pnetration of the welds, but reached the plastic load due to strain-hardening phenomenon. (4) The larger was the share of compression over that of torsion, the smaller the deformation capacity (√<(ε/ε_y)^2+(β′/β_p′)^2>) became. Finally, torsional behaviour of closed sections is compared with that of open sections; wide flange shapes (H-125×125×6.5×9).抄録全体を表示PDF形式でダウンロード (1109K) -

ジャーナル フリーCumulative plastic hinge rotations of framed structure subjected to alternating displacement, such as seismic disturbance, are presented in analytical expressions, and based on the analytical solutions, fundamental behaviors of cumulative deformation in the plastic hinges with non-hardening and hardening characteristics are discussed. The following features are pointed out. (i) Plastic hinge rotations in the frame with non-hardening hinge characteristic are accumulated lineraly with repetition of cycles under constant dislacpement amplitude. (ii) For hardening plastic hinge, cumulative rotations increase exponentially with alternating cycles and converge tosteady state after sufficient cycles. (iii) Final converged value of cumulative rotation depends substantially on the hardening characteristic of m-θ_p hysteresis. In the larter part of the paper a few comments on cumulative damage under random vibratlon are added.抄録全体を表示PDF形式でダウンロード (1072K) -

ジャーナル フリーIn the previous paper, the equations of the three dimensional elastic slope deflections were derived (§1., §2., §3). §4 in this paper, elasto-plastic slope deflection equations are established by introducing elasto-plastic stability coefficients. §5 refers to the derivation of the relationships of biaxial moments, thrust, curvatures and mean axial strain without using numerical integral calculus and determination of variable coefficients. These relationships are estimated from the moment-curvature relationships of the recutanguler cross section based on the way of thinking that the H-shaped cross section is constructed with three elements of rectangular cross sections. §6 refers to the analysis procedure for frames. In §7, adaptability of the presented method was investigated and the predicted loaddeflection relationships showed satisfactory agreement with experimental results which was discussed in (part I). The presented simple method of three dimensional elasto-plastic analysis does not need much complicated calculation and enables to investigate the three dimensional elasto-plastic behaviour of rigid frames constructed by many steel members.抄録全体を表示PDF形式でダウンロード (1047K) -

ジャーナル フリーIt has been proved that a system comprising a rigid body, a foundation and a number of bars each having one end coupled to the rigid body via a three-dimensional pin and the other end coupled to the foundation via another three-dimensional pin, has at least one degree of freedom allowing translation of the rigid body along a circular locus, provided that the lengths and directions of all the bars are the same as viewed in a projection on one plane. In case that the system comprises 5 bars, generally the system has one degree of freedom and no statical-indeterminacy. In case that the system comprises 6 or more (γ) bars, generally the system has one degree of freedom and (γ-5) degree of staticalindeterminacy. In the latter case, if the system is subjected to prestress, the potential energy due to the prestress and the gravity is a function of the position of the rigid body in the system, and the system becomes equilibrium when it takes a configuration which minimizes the potential energy. A tower could be constructed connecting systems like this unit system.抄録全体を表示PDF形式でダウンロード (1234K) -

ジャーナル フリーContinued from the preceding paper (the same title, Part I.), several wind tunnel experiments were made to investigate the behavior of airflow in urban area. In that paper (Part. I.), the characteristics of airflow in the regularly arranged city-block models were studied. In this paper (Part. II.), it is investigated how the airfiow behaves around a high-rise building existed in regularly arranged low ones. As a result, following remarks may be made. Case A : A high-rise building stands in the center of regularly arranged low buildings. (The former is four times as high as the latter.) Case B : Only low buildings are arranged regularly. 1) In case A, the values of mean wind velocity (U) on the side of the high-rise building increase up nearly 2.8 time as many as those of case B. 2) In case A, the values of turbulent intensity (φ) are less than those of case B. 3) Wind profiles above the streets to which wind direction is at right angles are nearly conform to the log-law in upper part (z≥z_0) in case B. 4) Models used in the resent paper are eight times as large in volume as those of this paper, but the characteristics of wind distributions in both reports give generally the same tendency in quality. 5) The pattern of vertical distribution of Reynolds' stress (√<-<u'w'>^^^->)s that the value of √<-<u'w'>^^^-> is nearly constant area above mode lhight in case B. In that area, wind profile conforms to log-law as a whole. 6) On the street to which wind direction is at right angles, space correlation coefficients are generally large, and on that with which wind direction is in parallel, those are small.

ジャーナル フリーThis paper is described a method of calculation of water consumption in the designing of building equipments about multi-storey flats and office buildings. Part 1 of this paper is described a theory of calculation of water consumption in simultaneous uses and per unit time in various water uses of these buildings. The probabilities of simultaneous uses of water can be obtained from the analyses of queueing theory. And in multi-storey flats, basic data which are used in the calculation are analysed about used frequencies, used times and used flow rate of water out of faucets.抄録全体を表示PDF形式でダウンロード (1208K) -

ジャーナル フリーThe purpose of this study is to define the concept "subsystem" of the building production system and to make clear various rules of the total system. In this paper "subsystem" is treated as a combination of both the physical portion of buildings and the job through which it is excuted. In the field of architecture, in order to grasp the function and performance of subsystems, it is effective that we consider the subsystem in relation to its own spatial domain. This point has already been accepted as for some building components such as sanitary units. But it has remained difficult to define the spatial domain assigned to components such as partition system that are axially allocated. In this paper, the spatial domain is characterized by its boundary, and the boundary section is classified into three types. (1) a straight line with one point defined on it. (2) a half line (ray). (3) a segment of a line.抄録全体を表示PDF形式でダウンロード (956K) -

ジャーナル フリーPlans for public housing should meet the various needs of its occupants but there is a wide difference in needs demanded by the occupants of council houses and those of JHC Houses. The object of our research is make distinguish the difference. Conclusions are as follows; (1) We observed various living conditions and many of them seem to be unsatisfied with smallness of the living/dining kitchen. (2) In houses of JHC the dining room is separated from the bed room and there is a demand for a separate living room. (3) There is a greater demand for more space by the occupants of council houses and an inclination to use one room for all purposes (4) Some of the occupants of the council house desire a room for their works-bag manufacturing, tailing etc.抄録全体を表示PDF形式でダウンロード (1315K) -

ジャーナル フリーWith the progress of urbanization, the public in urban areas has become a group of unconsolidated individuals which merely exist gathering together, each separated as a mass of sand grains. This situation, while supported by the high convenience and efficiency of modern urban system, has brought about a high-degree control of the mass, making the individuals objects of direction. This high-degree mass controlling society is the consequence of the Land reformation project aiming at a still higher productivity, which has also resulted in extensive destruction of living environment. Repulsion toward this situation has taken the form of local inhabitants' movements which base their subjective activities to save the situation on the autonomy of closely communicating regional collective bodies. The appearance of these solid communication groups, though still small in number, can indicate the future of community formation. Providing that this type of regional group with its own autonomous and continuous collective activities is a prototype of community, this research was done in view of finding in the inhabitants' awareness the possibilities of the group's developing into a community and other relating factors for this development. A questionnaire with indices to the discovery of the above factors was used, and the phase of the awareness of dwellers was analysed and considered according to the results. As the result, it was made clear that regional solidarity concerns permanent settlement that is made possible by the material and structural forms and conditions of the dwelling-houses; and that the collective body's subjective activities based upon its regionality help develop the dweller's sense of regional jointness.抄録全体を表示PDF形式でダウンロード (1662K) -
