摘要
阐述了单层索网点支式玻璃幕墙自由振动特性分析的特点,编写了相应的有限元程序,对索网结构的自振频率进行了计算分析,并讨论了节点质量、拉索截面积、拉索预应力等因素对其自振频率的影响。研究结果表明,单层平面索网幕墙结构自振频率密集,具有较强的非线性。
The characteristic analysis of point-supported glass wall free vibration is explained, and the corresponding finite element program is worked out to calculate the vibration frequencies of rope net structure. We discuss some factors such as node quality, the sectional area of rope, pre-stress of the rope acted on the natural frequency. The results show that the frequencies of the point-supported glass wall free vibration are concentrated and nonlinear.
