摘要
以某体育场大跨度钢筋混凝土平面曲梁为例,利用ANSYS对曲梁的截面进行分析优化。首先分析曲梁变形对其他周边构件的影响,其次通过参数化分析确定曲梁最优截面形式为箱形截面并且分析得到了最优截面尺寸。最后对整体结构进行静力和动力分析。结果表明,对梁截面进行优化后能够使整体结构达到一个较为理想的受力状态。
A big span reinforced concrete plane curved beams is studied and designed using ANSYS in order to get an optimal cross-section.First analyze the effect on the other peripheral components if the curved beam has a the deformation,followed by parametric analysis determine an optimal cross-section of curved beam in the form of a box-shaped cross section and get an optimal cross-sectional dimension.Finally,the overall structure of the static and dynamic analysis results show that the overall structure can achieve a more ideal stress state through optimizing the beam section.
