摘　　要：详细介绍了索网结构找形分析的非线性有限元法,编制了该数值方法的Matlab计算程序,然后进行数值算例分析.本文进行了马鞍形双曲索网模型成形试验,试验模型平面尺寸为1.8m×1.8m.通过分步分级悬挂砝码加载来控制索张力,测出了成形过程的平衡形态和最终平衡形态,通过试验数据、数值计算与解析比较,证明了计算方法的正确有效性.The non-linear finite element form-finding method was presented for the cable-net,the program was developed sequentially with Matlab language,and the numerical examples were carried out and verified with analytical results.Then,the form-finding experiment was performed for a hyperbolic cable-net,which was built with stainless steel wire rope mounted on the steel rig.The plain size of the test model is 1.8m×1.8m.Appling specified cable tension step-by-step and various grades in sequence with the cable passed...
