| 摘 要： | 钢-混凝土组合扁梁作为一种新型的组合梁具有承载力高、刚度大、结构高度小、防火性能好等优点,已逐步在多层建筑中得到应用,但是国内外对其承载性能的研究还很不充分,现有的计算方法尚需进一步研究和论证,设计计算依靠经验为主,限制了这种组合梁的广泛应用.采用非线性有限元的方法对简支钢-混凝土组合扁梁进行了全过程受力分析,揭示了这种新型组合梁的受力特点,讨论了计算方法的合理性.

| Abstract: | Steel-concrete composite slim beam,a new type of composite beam,has the advantages of higher strength and stiffness,lower structural height and better fire resistance.Therefore,it has been adopted in many multistory buildings.The research on the loading capacity of the beam is not adequate as the present theoretical models have not been verified by the test results effectively.Thus,the structural design of the beam depends mainly on experiences.In this paper,the nonlinear finite element method has been used in the analysis of the load-displacement response of the simply-supported beam,and the present theoretical models have been verified by the FEM results. |
