Abstract
The L-joints composed of SC (steel-plate composite) walls and RC (reinforced concrete) walls are common in SC structures, while limited studies have been conducted on them. This paper experimentally and numerically investigated the behavior of SC-RC L-joint. Four large-scale specimens were subjected to cyclic loading, where the wall-thicknesses and the core region types differed. Two core region types were involved, namely the S-type and R-type, where the core region belonged to SC wall and RC wall, respectively. The test results including the test observations, failure modes, load-displacement curves and load-strain curves were reported. For providing additional insights, the finite element models were established to simulate the behavior of the test specimens. Based on the test results, the current equations for calculating the joint shear force, flexural strength of RC wall and joint shear strength were evaluated and the recommendations on the design details were made.
