摘要

摘要: 基于非线性有限元数值模拟方法, 建立了考虑内衬混凝土的波形钢腹板精细化数值有限元模型, 基于试验模型的挠度与应变验证了有限元模型的有效性, 研究了波形钢腹板内衬混凝土部位的抗剪性能。分析了内衬混凝土波形钢腹板的抗剪机理、内衬混凝土与波形钢腹板抗剪能力的比例关系, 提出了波形钢腹板内衬混凝土部位的抗剪强度设计公式, 并验证了公式的有效性。研究结果表明: 数值模拟极限荷载为4 560 kN, 试验极限荷载为4 744 kN, 误差为3.8%, 并且数值模型和试验模型均显示了典型的斜向损伤区域, 因此, 数值模型是可靠的; 内衬混凝土受压杆与波形钢腹板受拉杆形成“X”桁架, 共同提供抗剪承载能力; 波形钢腹板的抗剪效应与荷载基本呈现线性关系, 内衬混凝土抗剪效应呈现出加载初期与后期发展较快, 加载中期基本保持不变的三折线的趋势; 抗剪计算公式计算结果与模型试验测试结果吻合, 计算值和测试值最大比值为1.1, 因此, 计算公式可靠, 可用于波形钢腹板内衬混凝土部位的抗剪性能分析。

Abstract: In order to study the shearing behavior of corrugated steel webs encased with concrete, the nonlinear-refined-numerical finite element model of corrugated steel webs encased with concrete was established, and its validity was verified by using the deflection and strain of test model.The shearing mechanism of corrugated steel webs encased with concrete was analyzed, the ratio of loads shared by concrete and corrugated steel webs was studied, and the shearing strength design formula of corrugated steel webs encased with concrete was presented and verified.Analysis result shows that the load capacities of numerical model and test model are 4 560 kN and4 744 kN respectively, the simulation error is 3.8%, so the finite element model is feasible.The steel webs'tension strut and the concrete's compression strut form X-type truss, and the shearing strength of corrugated steel webs encased with concrete is their sum.The shearing resistance of corrugated steel webs is basically linear relation with load.The shearing resistance of concrete encasement shows three polylines, it increases fast at the initial and late stage of loading, and scarcely changes at the middle stage of loading.The calculated result of presented formula ofshearing strength agrees with the model test result, the maximum ratio of shearing strength is1.1, so the formula is feasible and can be used to analyze for the shearing properties of corrugated steel webs encased with concrete.
