| Abstract | Today, several steel structural and composite high-rise and tall buildings have been designed and constructed using different lateral load resisting systems based on the seismicity level of their locations. The selection of proper structural system is important because the use of structural system with optimum effectiveness can give better seismic performance with minimum cost.This study deals with evaluating the structural behavior and performance of different steel-composite structural building systems. In this study, six types of different steel composite structural systems are compared for their seismic performance. These six structural systems are steel column moment resisting frame with shear wall, steel column building frame with shear wall, steel column building frame with shear wall and BRB outrigger, composite column moment resisting frame with shear wall, composite column building frame with shear wall and composite column building frame with shear wall and BRB outrigger. The seismic region for the proposed building is considered as Philippines which is one of the high seismic regions. The structural systems are analyzed using both linear and non-linear analysis procedures. For modelling and analysis, ETABS v21 version was used. In this study, all structural members are designed based on DBE level earthquake and are designed using AISC 360-16 for steel structural members and ACI 318-19 for RC structural members. Non linear analysis procedures are based on ASCE 41-17 and Los Angeles Tall Buildings Structural Design Council (LATBSDC 2020).The values of story drift, story shears, story moments, story displacement, wind displacements and tensile and compressive strains of shear walls of six structural systems are compared in this study to evaluate their seismic performance. The detailed comparison results obtained from this study will benefit for the application and optimization of these steel-composite structural systems in the seismic engineering field. |
