摘　　要：在对比各种确定预应力方法的基础上,引入刚性索法。利用刚性索法对选定的模型进行预应力的设定,对比设定前后结构的力学性能的变化,并与单层网壳对比。研究结果证明了本文采用刚性索法设定预应力的有效性,同时也表明刚性索法能更好的贴合预应力的设定原则、达到预应力的设定目标。Based on the contrast of the prestress determined methods ,puts forward the rigid cable method. Using the rigid cable method setting prestress to the selected model, contrasts the structural changes of mechanical properties before and after the setting, and compare with the single-layer shells. The results show that the rigid cable method adopted in this paper to set the prestress is effective. And it also shows that the rigid cable method can better fit to the setting policy and also meet the prestress setting goals.
