When pull plate (i.e. flange of beam)-plate thickness is 22mm. or 28mm.-welded into wide flange section member (i. e. Column)-its flange thickness is 40mm., 50mm., or 60mm. and web thickness 25mm., 50mm., or 40mm.-by Simplified Electroslag Welding using cored wire or manual arc welding and bended the latter by pulling the former (see, Fig.-1), brittle fracture was occurred in wide flange section member at and above its full plastic load at room temperature (see, photo.5). In this case, the ratio of the maximum deflection to the elastic limit deflection is 1.5〜8.8 (see, Table 7). Also brittle fracture of wide flange section member was occurred at room temperature in Case of X-type tests (see, Fig.-2). This phenomenon of heavy steel section is very important in design of structure of multi-storey buildings, and so these results are reported in detail in this paper with the results of supplemental tests and material tests (see, Table 1 and Fig.-3〜Fig.-7), and are analyzed qualitatively.

This paper is written regarding the ultimate strength of reinforced concrete wall panels with opening under uniform shear by using limit analysis, morever the relation between opening ratio, side ratio of panel and the decrease coefficient of shear responsibility. In this paper, it is assumed that the failure of reinforced concrete wall panels is based upon mohr's failure hypothesis. The Method of this study is approximate solution by upper and lower bound method using fundamental theory led by the late Dr. Ono and Dr. Tanaka. In last the validity of this solution is checked by experience result of Dr. Tomii. As the result of this study, it was proved that the decrease coefficient of shear force responsibility obtained from limit analysis, that is, the ratio of ultimate strength of reinforced concrete wall panels with opening to those without opening drops quickly in proportion to opening ratio and side ratio of panel.

On the thin-walled member, there is great difference between the torsional regidity of open cross section and closed cross section. This reason is as follow, that the condition of shearing stress is difference complytly. The purpose of this paper is to analyze the torsional problem of of the stiffened beam, which is in middle of their members, with the stiffness matrix method. The sttiffness matrix method is based on the finite element method, and in this paper, we substitute the simple polinominal for the deformed shape, agree it's coefficients with the degree of freedom, and assume that the bending rididity in thire plane is infinite. On this kind of beam, the deformation of cross section owing to the stiffened member is remarkable and the torsional rigidity decrease with this deformation. This fact shows that the old method, which is dased on the hypothese of underformed cross section, is unsuitable i. e. the method of the replacing the stiffened plate with an elastic reduced orthotropic plate equivalent. In order to check this theory, we try to experiment. Farther, we analyze the influence of boundary conditions and stiffened member upon the movement of the center of shear and the shearing flow with the stiffness matrix method and try to experiment.

Author calculated the response analysis on the vibration of the Elasto-Plastic steel arched frame due to the strong earthquake motions by using the electric digital computer, and discussed the influence of the displacements and the progression of yield members in the Elasto-Plastic steel arched frame elcted by the steel truss members or the steel full web members. This paper is the fifth report of the series on the dynamic response analysis of the space structure for the earthquakes. These results are as follows; (1) It is shown that the maximum displacement of the arch elected by the steel truss members is larger than the one of the arch elcted due to the steel full web members in the Elasto-plastic steel arched frame. (2) In this case the yield members are columns and springs but the progression of the yield members are different to the strong earthquake motions.

In this paper, a research is reported on wearing of a building, which was built about thirty years ago by the seaside for a resort hotel, worn by salt-damage and so demolished. It will be contributed to the fundamental data for building maintenance particularly in case of the seaside and also for building specification. The main results obtained were as follows. 1. Concrete and Finish; Cement and gravel was ordinary, but job was so poor that wall was especially porous and absorption ratio of water was very high. External finish was mortal and effect of salttight was also unexpected. 2. Neutralization; In side of wall was more neutralized than outside of wall because of human breath. 3. Crack; It was almost caused by corroision of reinforcing bar, especially in outside of external column and lowside of beam. 4. Salt-included; The maximum of ratio of salt included was 1.2〜1.5% in the seaside column and wall of first floor. 5. Rust of Reinforcing bar; Concerning a relation with rust and Cl, rust was a little when containing of Cl was nearly 0.10%, and rust was very much when Cl was more than 0.36%. Concerning a relation with rust, Cl and pH price, rust was always appeared when pH was less than 11.0 and Cl was more than 0.10%. 6. Rust of Alminium sash; Rust appear to the surface in 47% of all sashes (built about 4 years ago). In region of such seaside, alminium sash will be almost rusted by 7 years.

We have tried time studies about various kind of urban facilities to obtain foundamental data for design of the facilities and buildings. This is the first report of our several series of it. Here, we report such results of studies about factories, elementary schools, junior high schools, and senior high schools as follows; 1. On factories, modes of concentration curves are between 5 and 15 min. before beginning time of the work, and ratio of concentration in 5 mine. is about 25%. 2. On elementary schools and junior high schools, modes of concentration curves are between 0 and 15 min. before beginning time of the lesson, and ratio of concentration in 5 min. is about 23%. 3. On senior high schools, modes of concentration curves are between 0 and 10 min. before beginning time of the lesson, and ratio of concentration in 5 min. is about 30%.

On the occasion of regional development such as the construction of a large "New Town" it is requested to reorganize medical facilities. For this purpose it is fundamental to understand how medical facilities are used by and serve for the residents. This paper reports the following investigation of medical facility use in four J. H. C estates. 1. The neighbourhood medical facilities in and around the housing estate coverage differs after its location. 2. In case that the housing estate locatied in suburbs, about 15% of out patients and 50% inpatients used the neighbourhood facilities. 3. The neighbourhood facilities served mostly to female and child patients. the greater part of male patients used many hospitals in the mothers town.
