Abstract
Aiming at the difficulties in the field measurement of the large span spatial structure, we used self-developed wireless sensor remote monitoring system to collect and transmit the strain data of the steel structure of Hangzhou Olympic Sports Center Stadium during construction and service process. Based on load sensitivity analysis and component importance analysis, 828 strain sensors were arranged in different parts of the structure. And there were a total of four parallel chain-type networks for wireless transmission of data. Analyzing the monitoring data, the real stress change of the unloading process and the influence of the temperature effect on structure are studied in the paper.
