Efficient Preconditioned Soil–Foundation–Structure Interaction Approach to Compute Tall-Building Time Periods
The present paper suggests an efficient preconditioned two-iteration substructure approach—namely, preconditioned soil–structure interaction (PSSI)—to couple the analysis of a superstructure over fixed bases (which is traditionally carried out in design companies) with the analysis of foundation plates over an elastic half-space (EHS) to obtain more accurate equivalent supporting spring stiffnesses. Hence, an accurate building time period and, consequently, lateral loads could be computed. The effectiveness of the proposed approach is illustrated in several numerical examples in terms of number of iterations and scalability followed by comparison with previous work to demonstrate the superiority of the proposed approach.
