Abstract

Abstract

The behavior and ultimate capacity of multi-planar complex tubular joints in the steel roof structure withCHS members used in the T2 Terminal Building of Chengdu Shuangliu International Airport were experimentallyresearched．A special self-equilibrium spatial loading installation was designed．Two specimens with full scale of theirprototypes were tested under monotonic loading．Under the design loads, two specimens were kept in elastic．Underthe limit state, the chord of the two specimens deformed obviously and the failure mode was ductile．The non-linearanalysis of joints was done by ABAQUS．First the validity and the accuracy of the FE model were proved bycomparing with test results．Then, effects of several types of inner-stiffeners on the ultimate capacity and failure modewere investigated．The results indicate that arrangement of one inner-stiffener in center of joint can not only enhancethe ultimate strength and improve the stress state of joints, but also have better economical efficiency and constructionconvenience．
