Abstract

This study introduces a combined system of Rocking Shear Walls with Eccentrically Braced Frame with Vertical Link (RCSW-EBF). The aim of the study is to investigate the impact of the Force Design parameter (with different beta values) on the behavior of the RCSW-EBF system while keeping the cable area constant. Additionally, the study seeks to explore the effects of cable area on the behavior of the RCSW-EBF system while other characteristics remain unchanged. the 10-story frames are designed in SAP software, and the dimensions of the system sections are determined. These 10-story frames are then modeled in ABAQUS software, and their nonlinear behavior under pushover and cyclic analysis is determined. The finite element modeling has been done with Shell and Wire elements. The results of the cyclic analysis indicate that an increase in the percentage of Brace force (x%) leads to a corresponding increase in wasted energy and the coefficient of energy loss and reducing the design force of the Eccentrically Braced Frame's span and increasing the design force of the Rocking Wall with Concentrically Braced Frames' span led to a decrease in the cyclic diagrams of energy consumption. So, the energy consumption of the RCSW-EBF frame with the design forces of Braced Frame 70% and Rocking wall 30%, Braced frame 80% and Rocking wall 20%, and Braced Frame 90% and Rocking Wall 10% is respectively 12%, 28% and 44% more than the system with the design force of Braced Frame 60% and Rocking Wall 40%.
