for analyzing the structural dynamic behaviors time integration is the most versatile tool never theless the responses of time intergration are generally being obtained after considerable computational cost and are inexact being based on the notion of convergence and its role in time integration analyses the technique replaces seismic records with excitations digitized at larger steps in view of the role of power substation equipments in and after natural hazards and the experiences existing from the pst earthquakes the objective in this paper is to examine whether we can successfully implement the technique in time integration of real power substation equipment and eventually arrive at the knowledge about the behvioirs with less computational cost
