H型钢空间钢桁架节点抗震性能试验研究
|
摘要
考虑到模拟空间节点多方向受力的复杂性,将节点放在子结构单元中进行模型试验研究。通过对典型H型钢空间钢桁架子结构单元进行拟静力试验,分析了空间钢桁架子结构的主要破坏模式和空间钢桁架子结构的抗震性能;基于试验数据并结合实际工程,提出了空间钢桁架结构内力计算模型,及有关节点域设计的初步建议。
As is so difficult to simulate the fact suffer load circumstances of the space steel truss joint,the joint specimen is designed as a space steel truss structure cell.According to the pseudo static test of a typical space steel truss structure cell,the main destroy mode of the specimen are summarized,the hysteretic behavior of the specimen is analyzed. Based on the test results and the practical engineering,the calculate mode of the air- cooled condenser structure system and the original design methods about the joint are pointed out.
