EVALUATION OF RESIDUAL STRENGTH OF REINFORCED CONCRETE MEMBERS SUBJECTED TO REVERSED CYCLIC TORSION

This work aimed to gather basic data for evaluation of residual strength and deformability of damaged RC members. The behavior of members that had suffered damage during cyclic loading such as cracking penetrating into the cross section, plastic deformation, or partial failure was compared with that of a member tested under simple torsion. Reversed cyclic torsion was applied for loading as few studies have been reported in open literature, although it has been estimated to cause the most brittle failure. Analyses identified the effect of reversed cyclic torsion with varying numbers of cycles and with varying amplitudes on the reduction of residual strength and torsional rigidity. It was also confirmed that a closed joint encircling longitudinal reinforcement at the ends of transverse reinforcement was stronger and more resistant to deformation than a lapped joint.
