摘　　要：新型索桁架是在索桁架和拱的基础上,构思出的一种大跨度杂交桁架结构体系。本文对新型索桁架屋盖体系的静力与 动力特性分析进行研究,并采用能量变分原理进行求解,文中有算例说明其应用。A new type of cable-truss, a large-span hybrid truss structural system,is conceived on the basis of the cable-truss and arch. In this paper, the static and dynamic caracteristic analysis of a new cable-turss roof system is discussed and solved by the energy variational principle. A numerical example is also given for referance in practical design.
