For structures subjected to eccentric cyclic loads, torsion and combined loading coupled with torsion are usually observed on the structural members. These loads often induce unexpected structural responses causing premature failures of the composite members and undesirable structural performance in the inelastic stages. This study is focused on the improvement of seismic performance of hollow composite members subjected to eccentric cyclic loads. Sixteen composite members composed of encased steel tubes and high-strength reinforced concrete with inclined bars were fabricated for testing. Structural responses, such as strength and energy dissipating capacity, were compared to evaluate the member performance. The test results showed that the strength of members with inclined bars were significantly increased when subjected to torsion and combined loading coupled with torsion. Enhancement in energy dissipation further validated the applicability of incline bars to the performance improvement of the hollow composite members.
