Lift monitoring and analysis of multi-storey corridors in buildings

Abstract

Based on the steel corridor of the first-stage construction for Panzhihua City Government Service Centre, this paper introduces the integral lifting scheme of multi-storey long-span beam grillage steel corridor. To ensure the safety and stability in the lifting process of steel corridor construction and to prevent sudden overload from affecting the later normal use, the finite element simulation of steel corridor before lifting and real-time monitoring during the lifting process were carried out. The results of finite element simulation were compared with the stress and deflection data monitored in real time. It shows that the numerical data obtained from the finite element methods (FEM) are slightly larger than those from the actual monitoring. It follows that the results obtained from FEM for the lifting is safer, the data obtained from FEM and monitoring agree with each other, and, accordingly, the study shows that the monitoring approach is applicable. The integral lifting scheme and monitoring approach presented here can be used as an interesting reference for similar projects. • The integral lifting scheme of multi-storey beam grillage steel corridor is reasonable. • The method of monitoring stress and deflection data is simple and practical. • The remote monitoring system ensures the safety of the monitors. • Deflection monitoring device is a new inventive device. • The monitoring data are in good agreement with the finite element simulation data.
