Seismic Performance of an Exterior Joint between a Square Steel Tube Column and an H-Shape Steel Beam

This study developed a 1:2 scale model using T-shape steel with one-side bolts to connect square tube column an H-shape beam for quasi-static test investigate the mechanical properties and seismic behavior of semi-rigid joints. Within context, joint’s failure characteristics, hysteresis strain tendency under cyclic load were determined. In addition, this research analyzed force characteristics performance such joints based on outcomes. order further joints, ABAQUS finite element software was used establish numerical perform parametric analysis. The findings indicated that both sides joint is inconsistent, resulting in different performances joint. Selecting connector significantly affects capacity beam–column can be improved by increasing size steel. stability repeated good, their value rises steadily. Hence, type bolt suitable connecting closed columns other components. general, column–H-shape connection good recommended practical engineering.
