Anti-Seismic Behavior of Innovatory RC Frame Subjected to Severe Earthquake Action
The anti-seismic behavior of RC frame with buckling restrained braces (BRBs) subjected to severe earthquake action in seismic region was investigated in this paper. A design process of the buckling restrained braces used for stiffness-deficiency concrete frame structures was given, the design of the buckling restrained braces was conducted for a common frame structure, the layout of these braces in it was given by taking an actual engineering for illustrations, and the static analysis and time-history dynamic analysis were also performed. The results of computation showed that the use of buckling restrained braces has led to several functional improvements, such as the increase in structure stiffness, reduction of story displacement, and improved energy dissipation ability when compared with the frame without such braces. Analysis results showed further that RC frame with BRBs could absorb and dissipate seismic energy more effectively, improving anti-seismic performance of the framed structure.
