Asymmetric Seismic Response of SDOF Systems with Strength Deterioration
Abstract eng: Buildings with soft first stories may incur large deformations due to strength deterioration, which is caused by P- effect. The inelastic deformation of those buildings tends to shift to a single direction. This paper evaluates such biased response caused by strength deterioration and asymmetric property of input ground motion using SDOF systems. We defined a limit strength ratio R2 wherein the ductility factors for strength degradation systems are obtained by adding 2 to those for elasto-plastic systems. When R is larger than R2, the SDOF systems exhibit biased response and the response deformations lean heavily towards a single direction in any ground motion.
