Abstract
This paper investigated the seismic performance of 5 storied reinforced concrete buildings with the variable of the conditions of the bottom of the first story column and the top of the upmost story column in order to make uniform story drift distribution along the height of the building.The paper also proposed the method of the design of the frames to achieve the purpose.
It was concluded that the semi-rigid condition for the bottom and top of their columns was appropriate to the smoothing of the deformation and the proposed method was verified to be excellently effective for the uniform story drift distribution.
