The results show that the friction between hoop cable and joint will cause tension redistribution in hoop and radial cable of structure,led to uneven force distribution of the same hoop cable,increase displacement of some joints and axial stress of some bars in the lattice shell, and static properties of the structure will be obviously affected,but the dynamic and stability characteristic almost will not.

计算结果表明，环索与节点间的摩擦会导致结构环索及斜索张力重分布，致使同圈索力分布不均匀，使部分网壳杆件轴向应力和节点位移增大，对结构的静力性能影响最大，而对动力和稳定性能基本没有影响。

The main conclusions are those:(1) the cause of hot-dry climate before elevation of plateau is that the efficiency of atmospheric heat engine is lower than after the elevation owing to flatter global landform;(2) at the beginning of Oligocene Epoch,the horizontal scale of plateau reached the cr...

主要结论：（1）高原隆起前的干热气候是由于隆起前全球地势平坦，致使大气热机效率很低之故；（2）渐新世初高原的水平尺度达到了斜压大气地转适应的临界尺度，大气环流从南北两极&两涡对峙&突变成地球三极的&三涡鼎立&，气候发生突变；（3）分析了2.5Ma时高原抬升到2000m这一重要临界高度后大气环流的一系列相应变化；（4）计算、比较了最大冰期地气系统能量平衡与现代的差异，并由此分析了当时的气候状况
