| 摘 要： | 应用ANSYS大型有限元程序对本溪市体育馆钢屋盖进行有限元分析,得出该体育馆在静力荷载下的位移和内力,并进行了模态分析,采用子空间迭代法得出了体育馆的前20阶结构固有频率和前6阶振型.分析了该结构的动力特性,避免其在使用中因共振或疲劳破坏等因素造成不必要的损失,为进一步研究此类结构的受力特性提供了参考.通过对本溪市体育馆空间桁架的计算结果分析发现.空间大跨结构采用空间桁架也完全可以取得满意的效果.空间桁架的合理布置,可以使得各种杆件受力合理,充分发挥材料的性能.

| Abstract: | Finite element analysis of Steel roof of Benxi Gymnasium was made using ANSYS program.The displacements and internal forces of the struture under static load were obtained.A modal analysis using subspace iteration method was performed to get the preceding 20 natural frequencies and the preceding 6 vibration patterns.The dynamic properties of the steel roof were obtained to avoide the unnecessary losses due to resonance or fatigue damage.The computation provides a reference for study of the mechanical proper... |
