A Study on the Structural Performance of H-Beam-to-RHS Column Connection Reinforced by Increasing Column Thickness

Abstract

The structural behaviors of beam-and-column subassemblage reinforced by increasing column thickness at the connection area without inner diaphragms in addition to the horizontal haunch of beam at the connection side are investigated by the cyclic reversal loading test and finite element analysis. The case studies are presented to discuss the structural performance of beam-to-column connection by using finite element analysis and yield line theory with respect to two types of connection: (1) the beam-to-column connection reinforced by increasing the column thickness at the connection area, and (2) the beam-to-column connection reinforced by increasing the column thickness at the connection area with the horizontal haunch of beam at the connection side.
