装配式宽桥横隔板优化
|
摘要
为研究横隔板在宽桥中的作用以及布置优化问题,分别建立了跨径为20m和40m连续宽T梁不同宽跨比的有限元模型,改变其横隔板的位置和数量,通过比较横隔板不同布置位置对中梁挠曲变形的影响,得出了装配式宽桥横隔板的最优布置数量和位置.
In order to study the effect and layout optimization of diaphragm in the wide bridge,the finite element model was established for the 20 m and 40 m span continuous wide T beam with different width ratio.Changing the position and quantity of diaphragm,by comparing the influence of the different diaphragm position on deformation in beam deflection,the optimal placement number and location of assembly type wide bridge diaphragm were obtained.
