摘要
对Levy型索穹顶的索杆膜模型进行了动力特性分析,通过改变索穹顶的预应力水平参数,研究其对索穹顶动力特性的影响,结果表明,随着预应力水平的增大,结构频率增大,结构刚度呈增大趋势。
Dynamical characteristics of Levy cable dome with cable-strut-membrance model were analyzed.The effects on dynamical characteristics of Levy cable dome were studied by change prestress level,results proved that with the increasing of the prestressing level,the structure frequency increases,and structure stiffness showed increasing trend.
