Abstract
A support-type shear connector for basement composite walls was developed, and a push-out test and a finite element analysis (FEA) were performed to evaluate structural performance. For the support-type shear connector specimens, the ratio of the yield load to the nominal strength without applying the reduction factor was 0.83 and the ratio of the maximum load was 1.43. The ratio of the yield load to the nominal strength, to which the reduction factor was applied, was 1.38 and the ratio of the maximum load was 2.39. Thus, if the length of the support-type shear connectors is 35 mm to 100 mm, it can be designed with the nominal strength without the reduction factor applied. Additionally, the initial stiffness and maximum load of the support-type shear connector can be predicted using FEA with an error margin of within 10%.
