摘　　要：提出一种新型的拉索预应力网壳的布索形式,即用高强钢索代替网壳沿短跨方向的下弦所有杆件,每段索施加不同的预应力。对一拉索预应力双层柱面网壳模型,利用有限元计算软件ANSYS进行非线性分析,得出该结构的内力、位移分布特点及规律,为实际工程设计提供必要参数。A new form of cables for the prestressed lattice shell stru cture is put forward It means all the down string poles are replaced by the high strength steel cables along the short span and different prestresses are applied to every c able By calculating the model exam ple of two layer cylindroid prestr essed lattice shell structure,base d on the nonlinear analysis by ANS YS,the character of the stress and displacement of the structure are got,which will give necessary para meters to actual engineering desig n
