Assumptions and procedures of the analysis of reinforced concrete members were reported in the previous paper. (1) This paper is a report of experiments on reinforced concrete beams subjected to bending moment and shearing force. The purposes of the experiments are to obtain the data in order to compare and discuss with the results of the analysis, to examine the propriety of assumptions and procedures of the analysis and to investigate the behavior of reinforced concrete members. Two identical specimens are tested in order to obtain reliable data. Strain of reinforcing bars and concrete of the beams, deflections and average strain by which average curvature is calculated are measured by wire strain gauges, dial gauges and Weittemore gauge, respectively, and observation of cracks is done. Load-deflection curves, curvature distribution diagrams and load-strain curves are described with some considerations in this paper.

The behavior of a steel tall building frame under a varying horizontal force was studied experimentally, using cruciform model frames which were fundamental element of inner portion of multi-bay multi-story frames. Test frames were made by welding beams and columns of mild steel wide flange sections. In order to investigate the effects of the axial forces existing in the columns a variety of magnitude were given for the vertical loads. The ratios of column height to the radius of gyration and the beam-to-column stiffness ratios were also varied. A varying horizontal force was applied to a frame model under a constant vertical load on the columns. The experimental and theoretical behavior show as a general characteristic that the restoring force of a frame is reduced by the vertical loads. A fairlly well agreement is seen between the experiment and the two kind of theories which both take care of strain-hardening effects. The experimental frame failure loads, some of which have been presented in the previous papers, are compared with the two kind of ultimate frame strength formulas and these effectiveness are discussed.

As the general space loading on the corner H-columns, bi-axial bending moment gradient and uniform torsion under constant axial load are assumed. Some problems in theoretical analyses, arisen by applying torsion, are investigated and a few analytical examples are given. Problems particulary considered in the analysis are as follows; (1) use of sine and cosine for torsional angles (2) effect of cross-sectional rotation on curvature (3) derivatives of the co-ordinates of the torsional center (4) derivatives of the flexural-torsional rigidity (5) Shear force due to moment gradient (6) Yield criterion considering the interaction of normal and shear strain

The behaviours of the roof typed shallow hyperbolic paraboloidal shells with square site plans are investigated using the finite element method. How the displacements and stresses of the shells under the uniform load with pined boundary conditions on all four sides change when the number of division meshes changes is studied, and he accuracy of the present method is discussed from the comparison between the results of this method and the Fourier series expansion method. The comparison shows the good agreements of both displacements and stresses. The behaviours of the roof typed shell built up four equally shaped unit shells supported on the four corners are investigated mainly to get some knowledge about the effects of the stiffened beams attached as shwon in Fig. 14. The effects of the bending rigidities and eccentricity of beams against shell slabs and the two boundary conditions of the pined supports and the fixed supports are discussed.

This is the fifth report of the fundamental investigations for the planning of the public library system to community area. The paper describes the available range of "service area" of a branch library through the actural survey of residential distance of 3304 adult clienteles and 4906 child clienteles at the 9 branch libraries in both areas, Hino and Nagoya. We have found it through the calculating the ratio of the cilenteles to the population of every blocks in the "service Area". As the results, it was sure that while the closer people live to a library the moer they use it, the reducing tendency of the ratio of clienteles to population by a distance is not similary to every directions from the library but sharp towards the town center, slowly towards the opposite side of it because of their daily activity behavier. We present here, therefore, "contour line" like egg-shape, so to speak, which show the possible clienteles around the library, the available service area of the library itself. It seems remarkable also that there are no difference on the shape of the "contour line" between adult clienteles and child clienteles while the absolute vales of the ratio of child clienteles is far high compared to adult ones.

This is a part of a study on the method of distribution of regional facilities. In this paper, I report a new analytical method of distribution pattern of regional facilities. This new method is called "Spacing Method". The summary of this method is following. 1. With map, I measured the shortest distances between facilities, for instance, super markets in Osaka city. 2. The mathematical model with probability of randum distribution (for instance, Fig. 1) are equation (5) in linear space and equation (12) in second dimension space. (Fig. 3 and Fig. 5) 3. The distribution pattern of the markets (f_j) are compared with the randum distribution pattern (Fj). (Fig. 12) 4. By x^2-test, it is proved that the distribution pattern of the markets is not randum distribution pattern. 5. Fig. 13 (d=Fj-f_j) means that the distribution pattern of super markets belongs to aggregation type. Similarly, it is judged objectively that the distribution pattern of public ward offices in Osaka city is scatterd type and tailors in Tenjinbashi shopping street belongs to aggregation type. This method will be applied to the analysis of distribution of other regional facilities.

Present environment changes for the worse, and in swamming over the citizn's movement, this problems instance about urban planning in existace on the traces of scientifically, the object is environmental re-creation and inhabitants are in democratic urban movement. Therefore, pick up Nagata area in Kobe -a lot Maruyama- energetic civil movement in environmental improvement and describe four points : (i) What characters has Maruyama area in Kobe? (ii) The housing situation get serve aggravated and environment improve is a potent influence to level up essentially living. (iii) Further, environmental sanitation changes for the worse and inhabitants are concerned about it, and environmental re-creation is important problems for the every housing scale state. (iv) Increase these objective terms, near a few years, urban movement has developed by means of citizen's participation. It is clear that citizen's positive conscious, is formed in different classes scale.

In this paper, the relation between the ordinary system and prefabricated system is shown, supposing the process of the gradual progress of prefabrication from the ordinary system. The analysis about present condition of RC system apartment-house and PC system apartment-house is done. And after that the same method as this analysis is used for the study of the following each relation of 3 systems. The cost of the ordinary system using the pump-up-concrete is the cheapest and the cost of perfectly prefabricated system which is constructed by precasted concrete members of colums, beams, walls, and slabs is the most expensive. In the case of curtain-wall system of fire-proofed steel frame, the cost of the system that the curtain-wall is cement mortared with rass is ceap and ALC (Autoclaved Lightweight Concrete) system is expensive, but the difference between the two is about 5%. And about HPC (H shaped steel and precast panel) system, the cost of the system with reinforced concrete slab and precast concrete panel curtain-wall is the cheapest, though prefabrity is high. Yet the cost of the system with slab and precast concrete panel curtain-wall is the most expensive. In the case of wall system apartment-house, the prefabrity of high cost reinforced concrete apartment-house is low, and the prefabrity of low cost precasted apartment-house is high, but for other 3 systems the cost of high prefabricated construction is expensive. Therefore it is possible to consider that it is necessary to use higher prefabricated construction gradually, considering the barance between rising ratio of the cost of general works and fees of on-site labor.

This paper is an extraction of the system of KIWARI, from the analization of "DAIKU-KIKUJAKUSYU". Architecture essentially has an aesthetical delicate proportion of form. However, the art of KIWARI, not relying on designer's individuil ability, is inclined witn delicacy to rearrange each measure into an objective system of numerical values. Historically, the various conditions of architectural production at first had proportioned KIWARI's numerical value mainly in a simple 1 to 10 module. However, KIWARI's measure-system has the capacity to include a group of precise numerical values by setting up kinds of standard module and making it in turn decide each measure, systematizing each measure-organization of a main-system and sub-systems.

The characteristis of the design of the Sale and Reception Room of the KAITAKUSHI designed by J. CONDER, an English young architect in the 11th year of MeiJi (1878) are discussed in connection with the condition of life at that time. And the public estimation in the completion time-14 Meiji (1881)-are interpreted. The fate of the building aer explained. In October, 15 Meiji it altered to the head office of the Bank of Japan at the time of the establishment in buisness of that bank, and that lasted to April, 29 Meiji. Afterwards it changed to the club house of the above bank. In September, 11 Taisyo (1922) it wsa burnt down the interior by the big Kanto Earthquake, and thus was taken down. Finally the motive for this study and the significance as the object of the study are given.
