摘要/Abstract

摘要： 为保证结构在施工过程中的安全性及稳定性,采用施工过程分析数值模拟某多跨单层连续网壳结构的施工,基于模拟结果选取具有代表性的杆件作为测点,实时监测结构在整个施工过程中,因结构体系、传力路径、荷载条件和边界条件改变而变化的应力,并对比数值模拟结果与实测结果,预警结构在施工过程中可能出现的事故。研究结果表明:实测值能够反映结构在体系转换过程中的受力变化,验证应力监测系统和监测方法的正确性,建立在施工过程分析基础上的应力监测能够预警施工过程中可能出现的风险。

Abstract: In order to ensure structure safety and stability during construction process, process analysis was used to simulate construction of a multi-span reticulated shell structure. Then, based on simulation results, representative components were selected as measuring points to monitor stress changes due to structural system, force transmission path, load conditions and boundary conditions during whole process. Finally, results of numerical simulation were compared with actual measurement to predict possible accidents. The results show that measured values can reflect stress changes of structures during system transformation, and verify correctness of stress monitoring system and methods. Therefore, stress monitoring based on construction process analysis can predict possible risks during construction.

Key words: multi-span reticulated shell, construction platform, monitoring of construction process, steel truss, construction process
