摘要

摘要: 为实现单层网壳结构等大跨度空间钢结构的装配式安装,提出了一种由T形板、盖板、耳板、高强螺栓、封板和圆钢管等部件组成的外加盖板的T形板装配式网壳节点,用于实现大跨度钢结构杆件的装配式连接。通过调整各部件设计参数,可控制节点抗弯刚度和抗弯承载力的变化。采用数值模拟的方法研究了节点在网壳平面内、外方向的抗弯性能,分析了T形板翼缘厚度、T形板腹板厚度、盖板厚度、耳板厚度等参数对节点抗弯刚度、承载能力和破坏模式的影响规律。结果表明：外加盖板的T形板装配式网壳节点具有良好的抗弯刚度和承载能力,通过调整T形板翼缘厚度、T形板腹板厚度、盖板厚度和耳板厚度等参数,可以调控节点在网壳平面内、外方向的初始抗弯刚度的差值以及抗弯承载力的差值。

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.
