| Abstract: | The failure modes of full-width T-type RHS joints subject to static loading and the influences of geometrical parameters and load on the chord on their behaviors are studied by use of nonlinear finite element method in this paper. The design formula of full-width T-type RHS joints adopted by the new design specification of steel structures (GB50017-2003) is compared with the experimental data, the design formula used widely in foreign countries and the calculating results of nonlinear finite element. The results show that the design formula proposed by the design specification of steel structures in our country is reasonable and viable. |
