| 摘 要： | 基于HFWT体系的钢—混组合梁是一种新型的梁—桁混合体系(HFWT)的组合桥梁结构。文章通过设计制作了2片不同厚度的试验梁,通过两点对称静力加载试验测试了试验梁的荷载—挠度关系、交界面处混凝土板与钢梁的相对滑移、桁架应力、跨中截面的应变分布变化,分析了试验梁的破坏形态、变形特点和承载性能。研究结果表明:混凝土板厚大的试验梁其刚度稍大,而且延性更好。

| Abstract: | HFWT-based steel-concrete composite beam is a new combined bridge structure of Hybrid Full Web and Truss System.With two test beams of different thickness,the load-deflection relationship,the relative slipping at the interface between the concrete and the steel beam,the truss stress,and the stress distri-bution change in the mid-span cross-section are tested through the two-point symmetrical static loading,and deformation,characteristics and bearing performance of beam are analyzed.The results show that the thicker concrete slab is slightly better in stiffness and ductility. |
