摘要
核心单筒式悬挂结构中，因为四面开洞核心筒体在其顶部要承受巨大的悬挂荷载，所以，核筒的稳定是一个非常重要的问题。再者，四面开洞核心筒体的振动也是一个非常复杂的问题，必须提供一个简单而有效的分析方法。在假定位移的基础上，用能量变分法推导了核筒的屈曲荷载和振动基本频率，能为实际工程计算提供一定的参考。
In hanging structure with single core tube, since the core tube with holes in four sides withstands the huge loads of hanging floors at its top,its stability is a very important issue Furthermore,the dynamics of the tube is also complicated, a simple and effective analysis method must be put forward Based on the supposed displacement functions,the buckling load and first vibration frequency of the core tube are derived by variation method,and these can give some reference to pratical engineering computation
