摘要
对轻钢厂结构的单跨和整体结构进行了动力特性计算分析,结果表明,平面外刚度对动力特性的影响非常显著,在空间结构模型分析中,吊车质量对结构的影响并不比平面单跨情况下明显。
The dynamic characteristics of lightweight steel structure are also respectively calculated and analyzed in single span or whole structure. The computational results show that the out-planar stiffness has great influences on dynamic characteristics during the single span calculation;in the total structural analysis the crane has no evidently effect on dynamic characteristics with contrast to single span.
