Abstract

Many lateral force resisting systems are used in the structures, but no definite answer implies how the most suitable earthquake-resistant structural system is to be chosen for each type of earthquake severity, type of soil, and height of buildings. This research was conducted to choose the most suitable seismic structural system for different cases. The parameters being studied were seismic hazard level, soil classification, and structure height. Three lateral force resisting systems were tested, the bearing wall system using special reinforced concrete shear walls, the dual system of special reinforced concrete shear walls and moment-resisting frames, and the special reinforced concrete moment-resisting frame system. The dynamic and static analysis methods were applied using (ETABS) software to check the responses of the structures for 243 cases. Responses to critical values were grouped, compared, and checked according to code limitations. The special reinforced concrete-moment resisting frame system tends to be the most suitable in most of the cases except in soft clay soil sites for structures of risk category 4 in high seismic hazard sites as it did not satisfy the drift limitation. The duel can still be the most suitable system, but it needs to be modified by raising the stiffness or using bracing members. The dual system tends to be the most suitable in all cases and especially in soft clay soil sites and high seismic hazards and for the structures of risk category 4.
