基于塑性理论的钢-混凝土组合梁承载力分析

【摘要】 钢—混凝土组合结构是一种现代新型结构，能够充分发挥钢梁的抗拉强度和混凝土的抗压性能，是一种性能优越的组合结构。钢-混凝土组合梁因其受力合理，目前已逐渐应用于建筑结构中。钢和混凝土之间通过抗剪连接件相互连接，由于抗剪连接件提供了剪力，使混凝土和钢梁能够协同工作，充分发挥各自的作用，受力更加合理，因此分析该组合梁的力学性能对于工程应用具有实际意义。本文分析了组合梁分类和特点，得出了基于塑性理论的承载力计算方法。更多还原

【Abstract】 As a modern new structure, steel-concrete composite structure can give full play to the tensile strength of steel beam and concrete compression performance, which is a superior combination structure. The steel-concrete composite beam has been gradually used in the building structure because of its reasonable force. Steel and concrete are connected with each other through the shear connector, which provides the shear force to ensure that the concrete and steel beam can work together, give full play to their respective roles, and the force is more reasonable. Therefore, the analysis of the mechanical properties of the composite beam is of practical significance for engineering applications. This paper analyzes the classification and characteristics of composite beams, and calculates the bearing capacity based on plasticity theory.更多还原
