文摘

The seismic performance of retrofitted columns was investigated. Two different retrofit strategies were applied to the concrete columns. The effect of various retrofit methods on seismic performance of concrete columns was analyzed. Nonlinear modeling parameters for concrete columns specified in ASCE 41–13 were modified. The nonlinear load-deformation curves of retrofitted columns were established and verified.
