摘要
天津诺德英蓝国际金融中心采用巨型柱-剪力墙核心筒-环形桁架-伸臂桁架结构体系.作为典型高层钢结构建筑,工程规模大,主体结构受力复杂,要求进行实时内力监测.介绍了内力监测系统工作原理和测点布置原则,运用数值模拟计算主体结构竖向位移,通过测点理论值和监测值对比分析,保证工程施工阶段安全性,为类似工程施工提供参考和借鉴.
Tianjin Noble Winland International Financial Center adopts the structurel system composed of giant column,shear wall core tube,hoop truss and extended truss.As a typical high-rise steel structure,the project scale is quite large.In addition,the main structure accepts complex loads,so real-time monitoring is required.This paper introduced working principle of monitoring system and arrangement of measuring points. The vertical displacement of main structure was calculated by using numerical simulation.By comparing and analyzing theoretical value and monitoring value,we ensure the construction safety and provide a reference for similar engineering construction.
