文章基于挠度理论,建立悬索桥静力计算的基本方程,文中考虑了活载作用下挠度的一阶导数二次项的影响,详细讨论了所提出方程的数值求解过程,编制了MATLAB程序,分析了一个算例;文中算例考虑了荷载和温度变化情况下悬索桥的变形和内力,数值算例表明温度变化对悬索桥的变形和弯矩影响很大.

Based on the deflection theory,the nonlinear differential equation is derived for the static analysis of suspension bridges in which (dw/dx)~2 under live load is considered.The solution of the nonlinear differential equation is discussed in detail The program of MATLAB is designed for the static analysis of suspension bridges.One example is given in which the deflection and moment of suspension bridges are analyzed under dead load,live load and temperature change.The numerical result shows that the deflection and moment of suspension bridges are greatly affected by temperature change.
