NONLINEAR STATIC PROCEDURE FOR REINFORCED CONCRETE ASYMMETRIC BUILDINGS WITH LINEAR VISCOUS DAMPERS

摘要

In this paper, the Nonlinear Static Procedure (NSP) is extended for reinforced concrete single-story asymmetric building with linear viscous dampers. In this procedure, their responses are predicted through a nonlinear static analysis of MDOF model considering the contribution of linear viscous damper to the fundamental mode shape and an estimation of the nonlinear response of equivalent SDOF model using equivalent linearization technique. The peak drift of each frame predicted by the proposed procedure are compared with the results obtained by the time-history analysis. The results show that nonlinear response of single-story asymmetric buildings with viscous dampers can be satisfactory predicted by the procedure discussed in this paper.
