英文摘要：

A numerical algorithm based on the linear pre-stress of cable-strut structures. Without taking adjustment theory was presented to solve the initial into account the elements stiffness, the initial prestress of the multi self-stress modes structures can be obtained. This can simplify the numerical procedure and reduce time effectively. Finally, the initial pre-stress were investigated using this method for Levy cable dome. And furthermore the structural performances were evaluated comprehensively. The results show the initial pre-stress of Levy cable dome can be solved by this method and the struetural performance analysis has some valuable to be future structural design.
