摘　　要：在新科技时代的发展中,空中连廊[1]可以有效地解决各栋塔楼之间的连通问题,但由于其复杂的结构形式和受力分析的繁杂,计算目的除了要准确分析各塔楼自身是否安全外,还需把连廊和各塔楼结合起来考虑其整体受力。所以应对整体进行有效的弹性分析,本文结合佛山市的高层连体结构项目,利用MIDASBuilding及YJK软件进行小震弹性时程分析,YJK进行中震情况下的弹性分析,通过两个不同软件计算的结果对比,探索连体结构对各塔楼的影响和连接体自身的受力情况及其舒适度。计算结果表明:连廊的关键部位应采用两个软件计算所得的结果进行包络值设计,除此之外为了结构的安全性,还应在中震下验算连廊部位的破坏程度。而且连廊作为薄弱部位应进行专项分析,并采取板厚加大至250mm,配筋率不小于0.25%且双层双向拉通的加强措施。In the development of new technologies,skybridges offer an effective solution to connect various high-rise buildings.However,due to their complex structures and the intricacies of force analysis,our computational objectives extend beyond simply ensuring the safety of individual towers.It becomes necessary to consider the overall structural integrity by integrating the skybridge with each tower.Therefore,a comprehensive elasticity analysis of the entire system is warranted.This study,in conjunction with a high-rise interconnected project in Foshan City,utilized MIDAS Building and YJK software for elastic time history analysis under minor seismic conditions,and YJK for elastic analysis under moderate seismic conditions.By comparing results from these two different software programs,the study explored the impact of interconnected structures on individual towers,as well as the stress distribution within the connecting elements and their comfort level.The findings indicate that critical sections of the skybridge design should consider the enveloping values derived from computations of both software programs.Furthermore,to enhance structural safety,it is necessary to assess the extent of damage to skybridge sections during moderate seismic conditions.Additionally,considering the skybridge's vulnerability,specialized analysis is recommended,accompanied by reinforcement measures such as increasing plate thickness to 250 mm,maintaining a steel reinforcement ratio of not less than 0.25%,and implementing double-layered bidirectional strengthening measures.
