Abstract
For nonlinear time history analysis, employing a time integration method and some nonlinearity iterative method (for implicit analyses) is a broadly accepted practice. In 2015, the authors proposed a change in the analysis, according to which, when the nonlinearity iterations do not converge, the analysis proceeds to the next integration step. In this paper, this change, and no other change, is applied to seismic analysis according to the seismic code of New Zealand, NZS 1170.5:2004. The purpose is to clarify whether the change can increase the analysis efficiency. The possibility of improving the efficiency is shown via analysis of a tall building’s structural model. The observations are explained, discussed, and generalized. As a main result, the change proposed in 2015 may considerably improve the efficiency when the tolerance is sufficiently small and is ineffective when the nonlinearity tolerance is sufficiently large.
