However, besides the versatility and simplicity, the resulting responses are accompanied by many approximations, while the computational efforts are considerable. The main parameter controlling the accuracy and computational cost is the integration step size, a positive definite parameter, uniformly controlling the size of integration steps throughout the integration interval. For an efficient time integration analysis it is conventional to implement integration step sizes as much as small enough to provide sufficient accuracy. An exceptional case is time integration of structural systems, subjected to digitized excitations, when the digitization step size is smaller than the size essential for sufficient accuracy. In such analyses, additional computational cost should be spent, merely to consider the digitized excitations. Recently, a technique to overcome the deficiency is proposed and successfully implemented in time integration analysis of different practical cases, e.g. simple linear and nonlinear examples, tall buildings, bridges, silos, reservoirs. However, in all examples the seismic excitations are considered as one-component records. The aim of this study is to examine the performance of the recently proposed technique in dynamic time history analysis of a building structure subjected to a three-component earthquake record.
