| Abstract: | A method of evaluating the seismic performance of an earthquake damaged structure considering the influence of rebar corrosion was proposed,and the changes in structural seismic performance of the reinforced concrete structure considering rebar corrosion and earthquake action were analyzed.Through a numerical example,the validity and feasibility of this method were verified;then,the capacity spectrum curves of the damaged structure were got,after contrasting this capacity spectrum curves to those of a perfe... |
