摘要
本文介绍了4.4×6.8×0.48m棋盘形四角锥三层网架模型试验的方法及结果。试验表明,三层网架是一种安全可靠、刚度较大,内力分布更加均匀的新型结构。网架挠度、杆件内力的实测值和按空间桁架位移法计算的理论值吻合较好。
The test method and the test results of model of diagonal square pyramid space triple-layer grids with a size of 4.4×8.8×0.48m are presented. The triple-layer grids—a new type of space structure,with more safety, stability, rigidity and better distribution of internal forces are showed in test.The test results are in better agreement with those calculated by using theoret ical method.
