Abstract:

Methods are developed to reduce the computational effort in time-history analysis of nonlinear structures. The methods permit use of much larger time intervals than are possible in conventional time-history analysis. This can be done despite input containing large high-frequency components, frequent yielding and unloading in the structural elements, and the presence of degrees of freedom associated with high-frequency motions.
