【摘要】 通过对比研究了铝网架与钢网架在静力荷载作用下的受力特性及承载能力;比较了有无拉索的铝合金正放四角锥网架在受静载时,二者结构性能的差异,探讨施加拉索后对网架带来的影响;对比了拉索-铝合金预应力组合网架在静力荷载作用下,不同拉索预应力值、撑杆高度、布索形式、网格尺寸以及网架高度对网架结构内力的影响。更多还原

【Abstract】 The research on application of new material — aluminum in the space truss structure in the article. It counts the force characteristics and load capacity of aluminum and steel truss under static load; after that,it analyzes changes in mechanical properties of different materials arising due; Whether with cable structure of the aluminum pyramid grid under static load,the performance difference between the two structures,and explore the impact on the grid after having the cable structure. Cable-aluminum combined grid structure under static load,the different values of the pretensioned,pole height,arrangement of cable,the height of the grid mesh size and grid impact of internal forces.更多还原
