New Scheme to Resist Seismic Collapse of RC Frame

Abstract:

Earthquake would cause unacceptable damage in reinforced concrete structures. In this paper, two retrofitting methods based on alternative load path are proposed for the reinforced concrete structure. One method is to add steel braces to the structure, and another one is to add tension cables to the structure. Pushover analyses for all frames are carried out using SAP2000. From the analysis results, steel braces or tension cables delay the formation of the first plastic hinge and failure of columns, and can better improve the seismic performance of reinforced concrete frame. The research results can be utilized for displacement-based seismic design and seismic performance evaluation of RC structures.
