Description
Summary:Over the past twenty years, researchers have directed their efforts towards enhancing the earthquake resistance of concrete frames through repair and retrofitting. Two main approaches have emerged for bolstering the seismic resilience of previously intact structures prior to earthquake exposure. The first involves augmenting the existing structure with additional components like steel bracing, while the second entails reinforcing specific structural elements, such as employing steel cages. Seismic response analyses have been conducted on multi-story reinforced concrete (RC) frames originally designed without seismic considerations. This study aims to assess the effectiveness of retrofitting techniques by comparing the outcomes of employing steel braces, steel cages, and their combinations. The seismic performance is evaluated according to the RPA 2003 seismic code for Algeria, following the latest guidelines. Static nonlinear analysis was utilized to compare the seismic responses of existing non-ductile RC frames under various retrofitting schemes.
