摘要/Abstract

摘要： 为了研究钢-混凝土曲线组合梁的受力性能及横隔板影响,以跨径比(计算跨度与曲线半径的比值)和横隔板数目为参数,对6片“隔板式”简支曲线组合梁进行了试验研究和有限元数值模拟,分析了其在跨中荷载作用下的全过程受力性能、应变分布和结合面相对滑移规律。结果表明:跨径比的增大使曲线组合梁的弯扭破坏特征加强,横隔板数量对其影响不大;切向和径向应变均在有横隔板处曲线内侧小、外侧大,无横隔板处则相反;结合面切向和径向滑移均随跨径比的增大而增大,横隔板数目对切向滑移影响较小,但横隔板处径向滑移增大。因此横隔板对曲线组合梁的横向应变分布和径向滑移有较大影响,端横隔板对增加抗扭刚度作用明显。

Abstract: In order to study the stress behavior and diaphragm effect of steel-concrete curved composite beam, model test and finite element analysis were conducted on six simple model beams stiffened with diaphragms. The span-radius ratio and the number of diaphragms were taken as the design parameters. Under the concentrated load at the middle span of the beam, the whole process behavior, section strain and interfacial slip were analyzed. The results show that, with the increase in span-radius ratio the bending-torsional failure of the steel-concrete curved composite beam becomes more obvious; while the number of diaphragms has little influence on the bending-torsional failure. At positions close to the diaphragm the tangential and radial strains are small inside the curve and large outside the curve, which are reverse at position far from the diaphragm. The tangential and radial slippages between the concrete slab and steel girder both increase with the span-radius ratio; while the number of diaphragms has little influence on the tangential slippage, but the radius slippage increases close to the diaphragm. The diaphragms have large effect on the transverse distribution of the strain, and the end diaphragms can enlarge the torsional stiffness of curved composite beams apparently.
