Stress-Strain Monitoring and Assessment of Steel Beam in the Process of Column Demolition

Study on the construction monitoring was used to focusing on the Bridge and Tunnel. The construction of the steel structure workshop more and more appeared in the past few years, proper method of stress-strain monitoring of the key component while construction of steel structure workshop ,become particularly important factor to ensure the safety of construction process. Based on practical example of Jinbei automobile factory workshop, the paper describes the stress-strain monitoring of steel beam during column demolition. Through the design of test solution and the analysis of test data, get the suitable scheme of stress-strain monitoring, stress and strain field monitoring of the basic program, meeting the monitoring requirement whether steel beam is safe and reliable during column demolition, and could provide basis and support for similar conditions on-site monitoring.
