【摘要】 通过吊装阶段的动力分析,对张弦桁架结构平面外稳定性进行了研究,分析了张弦桁架动态吊装过程对结构平面外稳定的影响,指出在正常设计条件下,吊装过程中结构的平面外稳定性是较易满足的。更多还原

【Abstract】 In this article,authors study the out-of-plane stability of truss string structure through dynamic analysis during hoisting construction,and analyze dynamic hoisting course effect on out-of-plane stability of the structure.It is indicated that out-of-plane stability can be meet easily during hoisting construction,if the structure is designed normally.更多还原
