摘　　要：超高层复杂连体结构因其独特造型和宏伟气势,应用越来越广泛。但连廊安装过程具有一定风险,给施工安全带来巨大挑战。结构健康监测作为评估建筑结构安全的重要手段,为施工过程中结构安全提供重要保障。依托保利珑门超高层连体结构,通过合理设计健康安全监测体系,对结构整体吊装全过程进行应变监测,分析获得结构在不同起吊关键节点的承载力转换机制。采用有限元方法模拟实际结构边界条件转换及荷载变化,通过对比计算数据与实测数据,实现了对结构受力性能和安全状态的评估。Due to its unique shape and grand momentum,the complex connected structures of super high-rise buildings are increasingly widely used.However,the installation process of the corridor carries certain risks and poses a huge challenge to construction safety.As an important means of evaluating the safety of building structures,structural health monitoring provides important guarantees for structural safety during the construction process.By relying on the Poly Longmen super high-rise connected structure and designing a reasonable health and safety monitoring system,strain monitoring is carried out throughout the entire lifting process of the structure,and the bearing capacity conversion mechanism of the structure at different lifting key joints is analyzed and obtained.The finite element method is used to simulate the transformation of actual structural boundary conditions and load changes.By comparing the calculated data with the measured data,the evaluation of the structural stress performance and safety status is achieved.
