基于ANSYS的预应力钢—混凝土曲线梁桥静力分析

采用通用有限元软件ANSYS建立了一曲线形组合箱梁桥的有限元模型,研究了该桥在静力作用下的受力情况,分析计算结果表明该桥的设计满足静力承载的要求,在荷载作用下,最大应力发生在支座附近腹板处,最大位移出现在曲线内侧跨度较大的边跨跨中。

On static stress analysis of prestressed steel-concrete curve beam bridges based on ANSYS

The paper adopts the general finite elementary software ANSYS to establish the finite element model of the curved combined box beam bridge,researches the stressed situation for the bridge under the static effect,displays the results of the analysis and calculation that the design of the bridge meet the demand of the static stress loading,and indicates that the maximum stress occur at webs of the support,while the maximum displacement occur at the side span of the inner part of the curve with larger span.
