将单跨有吊车厂房模拟成单跨两层框架,中间框架梁两端铰接,模拟吊车桥架的联系作用,对其弹性屈曲进行了分析。分析发现,此时层与层的相互作用导致的同一层每个柱子的临界荷载的增加或者减小具有相同的比例。借助此规律,利用合并解法对框架进行了屈曲分析,发现合并解法具有很高的精度,这说明同层各柱是作为一个整体参与层与层之间的相互作用的,同时还说明梁的左、右两端提供给左、右柱子的约束可能不同,但是总和是不变的。
The single-span crane factory building is modeled as a single-span two-story frame, the middle frame beam is hinged at both ends, simulating the contact action of the crane bridge and analyzing the elastic buckling. The analysis shows that the interaction between layers at this time leads to the same proportion of the increase or decrease of the critical load of each pillar in the same layer. Based on this law, the buckling analysis of the frame is carried out by means of the merger solution. The results show that the solution of the joint solution has a high accuracy, which means that the columns in the same layer are involved as a whole in the interaction between layers and layers, The constraints on the left and right pillars on the right and left ends may be different, but the sum is constant.
