Abstract
An attempt is made to estimate quantitatively the influence of input damping parameters on both the equivalent linear analysis and the nonlinear analysis of R/C buildings, subjected to seismic loading. Two types of damping are considered: Equivalent viscous damping, defined as stiffness and/or mass proportional and, in the case of nonlinear analysis, hysteretic damping caused by inelastic deformations of R/C members. The reference structure used in the parametric analyses is a 9-storey R/C frame subjected to an input earthquake accelerogram. Selected results, including displacement time histories, hysteresis loops for critical members and envelope values of displacements, drifts, moments and ductility factors, are presented. It is concluded that the influence of viscous damping coefficients is significant in the case of the equivalent linear analysis and less important in the case of nonlinear analysis.
