Abstract

To assess the seismic performance of buildings reinforced by steel moment frames using built-in or external indirect joints, shear strength of indirect joints to be applied to computer-aided structural numerical models is required. However, Korea’s earthquake provisions do not provide the specified shear strength of indirect joints of specific seismic strengthened methods. In this study, an experiment was conducted to investigate the shear strength of indirect joints in the built-in and external seismic strengthened methods with specific indirect joints. It was confirmed that the shear strength of the indirect joint was determined to be a conservative value among the interfacial shear force of the post-installed anchor and the shear strength of the load transfer part. It was also confirmed that the indirect joint exhibited the same shear strength regardless of the type of seismic reinforcement, and the shear strength of the indirect joint was provided. In addition, a method of calculating the shear strength depending on the number of load transfer parts and the thickness of indirect joints was proposed.
