Abstract

Abstract

In order to realize the assembly of long-span steel structures such as single-layer reticulated shell, the T-shaped steel joint with cover plates (TSJC) was put forward, which can be used to connect circular steel tubes of single-layer reticulated shell. The TSJC joint consists of T-shaped plates, cover plates, ear plates, high-strength bolts, sealing plates and circular steel tubes. By adjusting the design parameters of components, the bending stiffness and bearing capacity of TSJC joint could be controlled. Finite element models of TSJC joints were established and the flexural performance of TSJC joints in in-plane and out-plane direction were analyzed. The influence of the thickness of T-shaped plate flange, T-shaped plate web, cover plates and ear plates on the bending stiffness, bearing capacity and failure modes of TSJC joints were studied. The results showed that the TSJC joints exhibited good bending stiffness and bearing capacity. By changing the thickness of T-shaped flange plates, T-shaped web plates, cover plates or ear plates, the differences of the bending stiffness and bearing capacity of TSJC joints in in-plane and out-plane directions could be controlled.
