Abstract

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
