Experimental study on steel bridge piers with inner cruciform plates subjected to cyclic lateral loads

摘要

The strength and ductility of steel bridge piers with inner cruciform plates were studied experimentally. A total of 4 specimens with inner cruciform plates and compact sized sections were tested under constant compressive axial and cyclic horizontal loadings. The effects of inner cruciform plates on the ductility and strength of bridge piers were investigated. It was shown that piers with inner cruciform plates had increased ductility and energy absorption capacity.
