摘　　要：某中学行政楼为双塔大跨度连体结构,双塔采用框架—剪力墙结构,连体部分采用钢桁架.文中介绍了连体结构设计特点、计算分析和设计准则及采取的相关措施.分析了连接体部分设计特点,连接体楼板在温度、地震作用下应力情况和舒适度情况,以及连体的施工顺序对楼板的受力影响,根据分析结果对连接体楼板采取加强措施.对连接体桁架采取抗震性能设计和抗连续倒塌设计,保证结构的关键构件的安全度.对今后的连体结构设计提供了一定的借鉴意义.The administration building of a middle school is a double tower long-span connected structure.The dou-ble tower is a frame shear wall structure,and the connected part is a steel truss.This paper introduces the design characteristics,calculation analysis,design criteria,and relevant measures of the connected structure.The design features of the connector are analyzed in detail,including the stress and comfort of the connecting body floor under the action of temperature and earthquake,the influence of the construction sequence of the connecting body on the stress of the floor.Corresponding reinforcement measures shall be taken for the connecting body floor according to the analysis results.The seismic performance design and progressive collapse resistance design are adopted to en-sure the safety of the key components of the structure,which can be used for the reference in the future design of con-joined structure.

关 键 词：连体结构 大跨度钢桁架 施工模拟 抗连续倒塌设计
