Abstract
In this research, finite elements analysis is utilized, using SAP2000, to study the effectiveness of different techniques on the seismic retrofitting of existing reinforced concrete framed structures. The models are considered for reinforced concrete framed structures; and seismic evaluation is conducted. These models represent typical structures that were designed and constructed before and after the current Saudi Building Code, SBC-2007. The seismic evaluation was conducted using SAP2000 Program. This study focuses on performance based design of three multi-story RC framed buildings in Madinah, Saudi Arabia, subjecting them to monotonically increasing lateral forces with an invariant height wise distribution until the preset performance level (target displacement) is reached. Considering the deficiencies indicated in analysis, these buildings are redesigned by adopting retrofitting techniques such as shear wall, bracing and column strengthening. These techniques strengthen structures to reach the targeted performance level. The results indicate the effectiveness of each technique and how applicable it is to be used for seismic retrofitting of structures in Madinah, Saudi Arabia.
