| 摘 要： | 利用ANSYS有限元分析软件建立了1个单榀钢筋混凝土框架结构整体基准模型及相应的4个简化模型.以动力型冲击荷载为例,分别计算了框架柱在3/4柱高、1/2柱高及1/4柱高3个不同部位受到撞击作用时的结构的佗移动力反应时程.计算结果表明,在数值分析时,可以将整体框架结构简化为2层2跨的简单框架或十字型结构.抗撞击试验模型可...

| Abstract: | A primary standard model and four simplified models were presented with ANSYS for a reinforced concrete frame structure.The structural response was calculated for the dynamic loads applied at 3/4,1/2 and 1/4 column height,respectively.The results showed that it is reasonable to reduce the entire frame to a frame of 2 storey by 2 spans or a cross frame when carrying out numerical analysis for a single column.It is also a practical approximation to reduce the frame to a 2 end-fixed column in experiment.But it... |
