| 摘 要： | 在工业与民用建筑中,当跨度较大时,屋盖的承重结构多用桁架.其中,梯形桁架的应用较为广泛.梯形屋架斜腹杆的设置方向对梯形屋架的受力状态有一定的影响,基于此,本文使用大型有限元分析软件ANSYS12.0,对不同斜腹杆设置方向的屋架进行了分析,通过比较其受力、变形和动力特性,得出斜腹杆的一种较为合理的设计方法.

| Abstract: | In industrial and civil buildings,when the span is large,it is uneconomic to use the beam to bear the load of the roof,and at this time,the truss is widely used,especially the ladder truss.The tilted belly poles of the ladder roof truss is some influences to the forced state of the ladder roof truss.Based on this reason,this paper analyses on the two kinds of installing direction of tilted belly poles by ANSYS 12.0-a large-scale finite element analysis software,and a better design method is obtained through comparing the force analysis,deformation analysis and modal analysis. |
