Abstract

Abstract: In order to monitor structural safety status during the operation of tower crane, improve the quality of safety technology management of tower crane, firstly, according to characteristics of structure motion, monitoring parameters were divided into static monitoring parameters and dynamic monitoring parameters.Then, principles of selecting static measuring points and dynamic measuring points were proposed, and layout method of stress, deformation, temperature, wind load, acceleration and other types of measuring points were given. Finally, taking tower crane in service of Lepu building in Shenzhen as monitoring object, this method was applied to implement structural safety monitoring of tower crane.The results show that monitoring data of each measuring point are in good agreement with the numerical analysis results.Tower crane in the use of the process is always in a safe state.

Key words: tower crane, structural safety, monitoring parameters, arrangement of measuring points, warning level
