ABSTRACT

In this study flat plate structures designed only for gravity load were retrofitted against earthquake load using various methods and their seismic performances were evaluated to verify the effect of the seismic retrofit. Both the element level retrofit scheme such as column jacketing and the system level scheme such as installing steel braces between columns were employed. The nonlinear static and dynamic analysis results showed that both strength and stiffness were enhanced as a result of the seismic retrofit. Among the retrofit schemes steel braces were most effective in increasing stiffness as well as strength, and the effectiveness depended on the size of additional steel columns connected to the braces. Also the effect of column jacketing was significantly increased when the critical section of column-slab connection was reinforced by steel plate.
