摘要
椭圆平面双曲抛物面索网采用封闭的空间曲梁作为边缘构件，受力合理，是工程上经常采用的悬索体系形式。本文给出这一类典型索网结构的自振频率及振型图和自振频率随结构参数、几何参数的变化情况。
This paper analyses the free vibration characteristics of hyperbolic parabaloid cable nets with ellipse plans which are applied in engineering frequently as its good behavior of bearing loads The natural frequencies and periods of vibration, and their variation with the structural and geometric paramerers are put forward
