Abstract

The purpose of this paper is to investigate experimentally the strength and deformation of T-joints to improve the structural behavior of truss connection consisted in square hollow steel section. There are two-types to be changed in T-joint shape. One type is TP-series that a brace member is rotated to 45 degree, another type is TR-series that a chord member is rotated to 45 degree. The most important results obtained from the 2nd experiment on the T-joints is as follow; The yielding strength and initial stiffness of TP-series increase more than a current type(TS-series) in $0.6{\leq}{\beta}(d/D){\leq}0.7(0.85{\leq}{\beta}$'$(={\sqrt2}{\cdot}{\beta}){\leq}1.0)$.
