Abstract

In the present study, the seismic behavior of self-centering rocking wall systems in both types of base-rocking and double-rocking was investigated. To conduct seismic analyses, three sets of seismic records were considered including 22 Far-Field (FF) ground motions and 28 Near-Field (NF) ground motions that half of which are Pulse-like (Pulse). These ground motions were used for nonlinear time-history analysis of structures with 8, 12, 16 and 20 floors. Based on the area of prestressing cables, three types of double-rocking walls are considered and compared with the base-rocking and the fixed base walls. Numerical modelling was conducted via OpenSEES software in two-dimensional space. For the sake of validation, the available experimental data of base rocking and fixed base walls was used. To compare the seismic performance of the structures, some desirability coefficients have been defined. These coefficients were based on the reduction of the higher mode effects and the reduction of the inter-story residual drifts. The results showed that generally, the double-rocking walls provides higher desirability coefficients than the other considered systems. Furthermore, the double-rocking walls by reducing the cable area in the bottom block (R2-H1) are more
