Plastic design formulae including the effect of residual stress can be derived by extending Jezek's method, as is in Part I. Centrally loaded column curves with the effect of residual stress are also investigated.

The ultimate strength of the framed structure subjected to seismic force is investigated. Our method is based upon the static analysis of the load-deflection relation of the structure and the dynamic response of the vibration system. As a result it is demonstrated that the ultimate strength is largely affected by the strain-hardening property of the material.

Author showns the numerical method of responese analysis on the vibration of steel arched frame due to strong earthquake motion by using the electric digital computer, and discussed the accuracy of the displacement according to response spectrum, the influence of the stresses due to horizontal and vertical of the ground motions and the distribution of the seismic coefficient. This paper is the second report of the series on the dynamic response analysis of space structures by earthquakes. These results are as follows : (a) In case of the calcutation of displacement of the steel arched frame from the response spectrum get near the actual displacement by extracting the square roat in the sum of self multiplation. (b) It is shown that the maximum bending moment in the steel arched frame exceles due to horizontal ground motions. (c) It is shown that the maximum axial force in the steel arched frame exceles due to vertical ground motions. (d) It is shown that the maximum shearing force of the column in the steel arched frame is larger about 2.0〜2.5 than arch. (e) It is shown that the distribution of the seismic coefficient in the steel arched frame is similar to the mode shape of the excellent period due to earthquakes.

One of the present authors has been studied numerically the interaction curves taking account of the bucklbending (bending under the beam-column effect) on the plastic collapse and the buckling collapse by M. Kuranishi in the case of the unbraced multi-story frames with the initial plastic hinges to be formed at the base of columns. On the other side, the buckling behavior of unbraced frames resach has been so developed that plastic design metohd was prepared as the lecture note at the Lehigh Univ. and others. The most of them were presented as the approximate design methods without buckling collapse that presumed ultimate load by the iterative procedure or compatibility analysis etc. However, in this paper, present authors proposed the systematical analysis method under the assumption to given virtical loads and fixed critical sections at a given place of yield hing in order to treated the ultimate lateral loads in cluding the buckling collapse as a whole of frames. Then, the main paints of our procedure were much the same as the compatibility analysis to expected that newly considered the criterion called the Feimberg's Stability Condition. Finally, the unbraced 1 bey 2 story frames were innestigated as numerical examples.

In this papers, we analyse stress and deflection (strain), and behavior of buckling and vibration of spaced trussed members by finite deflection method. The basic equation of this method is simply expressed by stiffieness matrix. In the basic equation of stress and deflection (strain), we have taken up next three methods, and compared each other. 1. Non-linear equation by finite deflection method. 2. Linear equation by finite deflection method. 3. Linear equation by general method. For obtaining the basic equation of buckling and vibration by finite deflection method, we use linear method for simplification. In approaching this problem, we consider two cases, for spaced members with strain loaded and other without strain. To add, in order to afford better understanding about several basic equations, we analyse a few simple examples.

Pattern and stability of seasonal fluctuation of building starts are various by type of owners. Besides, the seasonal fluctuation pattern itself seems to change gradually. The pattern of "individual" is the most stable and "companies and other corporations" is the least. The pattern of individuals is significant. The peak comes in the summer and it does not change over the years. The pattern of "govermments" is also significant and the peak comes at the end of the year. The peak shifts during the former half of the period of analysis. The pattern of "companies" is not significant because of strong irregular factors. It also seems to have some tendency to shift to the opposite direction. The government and others are in a complementary relation imperfectly with each other. Paticular strong irregularity seen in December of 1959 corresponds with the change of building codes. S-I Factor is the seasonal and irregular factor calculated approximately by Census Method II-XII, Dept. of Commerce, Bureau of the Census, U.S.A.
