摘　　要：介绍了钢筋混凝土体外预应力梁几何非线性影响因素,分析了设置双转向架的钢筋混凝土体外预应力梁的几何非线性分析,并与试验结果及ANSYS分析结果进行了比较,研究结果表明:钢筋混凝土体外预应力梁具有明显的几何非线性;体外预应力梁几何非线性影响效应与梁的跨度等因素密切相关。Introduces the influence factcrs of geometrically nonlinear performance of externally prestressed concret beams.The paper carries out the geometric nonlinear analysis of external steel reinforced concrete prestressed beam of double-direction fram,and compares it with experimental result and ANSYS analysis result as well.The results showed that externally prestressed concret beams obvious geometrically nonlinear performance.And it has correlation between geometrically nonlinear and span of beams.
