【摘要】 高层连体结构已成为现今高层建筑中应用十分广泛的结构形式，随着人们对连体结构抗震问题的不断深入研究，国家规范条文也在不断的完善，但是规范对于连接体的连接方式与连接体的位置选择并没有做出明确的规定。总结历次地震资料，我们发现，在地震作用下，连体结构的破坏严重，连接体本身塌落的情况较多，同时也使主体结构中与连接体相连部分结构严重破坏。本文对实际工程算例进行简化并建立了不同跨度下、连接体分别位于不同位置的多个模型，使用振型分解反应谱法对各个模型进行了分析对比，并用时程分析法对所得结果进行验证。在设置分析模型时，主要考虑了以下几个对比条件：1.主体结构的层数；2.连体结构的跨度；3.连体结构的连接方式；4.连接体的连接位置（上部、中部、下部）。通过各模型的对比分析，对主要影响整体结构的参数（周期、楼层位移和层间位移角等）以及部分构件内力进行了分析和对比。重点研究了地震作用时，不同跨度下位于不同位置的连接体对框架-剪力墙主体结构的影响。得出的主要结论如下：1）高层连体结构的跨度较小时，不同情况下连接体对高度较高的结构影响更大。2）连接体跨度较小时，宜采用刚性连接，连接体的设置使结构振动在各个方向的因子发生了改变，侧振和扭转振型的耦合效应也更加明显；连接体的位置越高，结构的周期越长，位置越低，对结构的影响越小，但连接体位置较低时，结构的抗扭转性能变差。3）连接体跨度较大时，连接体宜采用钢结构桁架形式，连接体采用弱连接方式时对结构的影响小于采用强连接方式；采用强连接方式时，连接体位于上部时结构的周期比最小，抗扭转性能最好，位置较低时抗震性能较差；采用弱连接方式时，结构局部构件内力有所增大，但对整体的抗震性能影响较小。4）大跨度下，由于受到温度、地震等不利因素的影响，连接体宜设置为钢结构屋盖形式，并与主体结构两端采用弱连接方式，采用这种结构形式时连接体对结构的影响很小。更多还原

【Abstract】 Senior Siamese structure has become a very wide range of applications in themodern high-rise buildings, structures, along with the deepening of the the Siameseseismic problem, national norms provisions also constantly improving, but thespecification for connection connection connectionselect the position of the body anddid not make clear. Summary of previous seismic data, we found that the earthquake,the Siamese structural damage is severe, connecting body slump of more seriousdamage, also part of the structure of the main structure and connected to the connectorbody. Practical engineering examples to simplify and create a different span, theconnector body are located in different locations of multiple models, use vibrationresponse spectrum method were analyzed and compared for each model and the timehistory analysis resultsverification.In the Settings analysis model, mainly consider the following a few contrastconditions:1. The main structure of the layer;2. Connection body structure of the span,3. connection mode of the Connection structure;4. Connection body position (upper, middle and lower).Through comparative analysis of the various models, mainly affect the overallstructure of the parameters (period, floors displacement and layer displacement angle,etc.) as well as part of the member forces were analyzed and compared. The focus of theearthquake, the different spans located in different locations to connect the body on theframe-shear wall of the main structure. The main conclusions are as follows:1）The smaller of the span of the top piece structure, the different situations of theconnecting body on a high height structure greater impact.2）Narrow span of the connector body should adopt a rigid connection, connectedbody set changed factor in each direction of the structural vibration, lateral vibrationand torsional vibration mode coupling effects are also more pronounced; The higher theposition of the connecting body, the structure of the cycle is longer, and the lower position, the smaller the effect on the structure, but the lower position of the connectingbody, the structure of the anti-reverse deterioration.3）Span large connector body, connector body should adopt the form of a steelstructure truss connection the body weak connection structure is less than strongconnection; When a strong connection, the connector body is located in the upper partof the structure of the cycle than the minimum anti-torsion properties best poor seismicperformance, low position; weak link, the structure of the local member forces hasincreased, but the overallseismic performance was less affected.4）Long span, due to the impact of unfavorable factors such as temperature,earthquake, connecting the body should be set to the form of steel structure roof, andboth ends of the main structure of the weak link, using this structure connected to thebody structure small.更多还原
