Abstract

The authors have proposed Step-over Isolated Structure system as one of the extension methods for multistory housings. In this system, stability consideration for the supporting columns is essential, including P-Δ effects and plastic deformation of columns. In this paper, the effects of such combined non-linear characteristics of the columns on the stability and seismic response of the system are studied and discussed.
