Abstract:
Taking a typical reinforced concrete(RC)frame structure that was close to the epicenter during the Wenchuan Earthquake as background, the seismic collapse resistance of the frame was strengthened by attached substructures, including conventional brace, buckling-restrained brace(BRB)and viscous damper brace. Seismic collapse fragility analysis method based on incremental dynamic analysis(IDA)was implemented for each strengthening scheme to compare their effects and to analyze the influence of critical parameters. The results show that the viscous damper brace strengthening scheme performs better than the BRB, and the BRB performs better than conventional brace. With the same strengthening parameters, the strengthening effect of A-shaped bracing scheme is better than that of the X-shaped scheme.
