Interest in modular buildings has surged recently, leading to their construction at increasing heights. However, seismic performance evaluations for modular connections remain insufficient. Based on Jang's (2019) experimental research, this study validates an analytical model and conducts parametric analyses on the shear strength ratio between the panel zone and beam, and the width-to-thickness ratio of the bracket. When the panel zone-to-beam shear strength ratio was 1.5 or higher, plastic hinge formation shifted from the panel zone to the beam. Consequently, a shear strength ratio between 1.5 and 2.0 is recommended. Analysis of the bracket’s width-to-thickness ratio revealed local buckling in models with non-compact sections, suggesting that brackets in modular connections be designed with compact sections or greater to enhance structural performance.
