Numerical Study of PZ Strength Effects on Cyclic Seismic Performance of RBS Steel Moment Connections

패널존 강도가 RBS 철골모멘트접합부의 내진거동에 미치는 영향에 대한 수치해석적 연구

Effects of panel zone (PZ) strength on cyclic seismic performance of the RBS connections was studied based on the validated finite element analysis. High-profile cyclic correlation of finite element model with the full-scale test results based on the material and geometric nonlinear post-buckling analysis was among the most significant consideration in this study. Numerical response results as affected by the panel zone strength reproduced the experimentally observed results quite reasonably. The finite element modeling capability of this study can be used to supplement or to replace in part the costly full-scale connection testing.
