Abstract
This paper shows some examples of structural analysis for the two cases of the 8-strories building during the three kinds of earthquake motions by using electronic digital computer. From this result, we obtainned the conclusion as follows; (1) These building vibrate in their own first natural period and we have to notice the residual displacement in upper story of building of which the restoring force characteristics is of perfect plastic type and of which the damping factor is small. (2) The spring constant ratio in the elastic range and in the plastic range, and the damping factor for the building have influence on the structural response considerably. (3) From the examples of the structural response during the different kinds of earthquake motions, the earthquake motion which give the bad effect for building can not be simply determined. (4) The distribution of the yield shearing force coefficient should be taken to be smooth and this distribution have to be determined as concerned with the distribution of ductility factor.
