摘　　要：通过有限元软件ANSYS对体外预应力组合梁进行了非线性分析,采用COMBIN39单元模拟栓钉的抗剪性能以考虑组合梁的滑移效应,计算结果与试验值吻合较好。并对比分析了不考虑滑移效应的组合梁的受力性能,结果表明,滑移效应使组合梁的承载力降低,而变形增加。In this paper, ANSYS is used to analyze the nonlinear capability of steel-concrete composite beams prestressed with external tendons, and stud is simulated by the element COMBIN39 to study the slippage effect of composite beams. The calculations are consistent with the test results. And also the composite beams without slippage effect is contrasted, the results indicate that： the slippage effect reduce the bearing capacity and increase the displacement of the composite beams.

关 键 词：ANSYS 组合梁 滑移效应 非线性
