New speedup algorithms for nonlinear dynamic time history analysis of supertall building structures under strong earthquakes

Summary Some speedup algorithms oriented to improving computational efficiency of nonlinear dynamic time history analysis of supertall buildings structures excited by strong earthquakes are proposed. In order to minimize Jacobian factorizations, the inexact Newton algorithm combined with the sparse...
