Comparative Study on Ultimate Stress Test and COMSOL Analysis of Steel Beam of Pull-Up Cantilever Scaffold

Abstract

Combined with the actual project, the mechanical properties of the cantilever steel pipe scaffold system are tested by model test, including the bending stress, vertical shear stress and vertical deformation displacement of the test steel beam. The stress state of the cantilever steel pipe scaffold system is analyzed, and the mechanical properties of the cantilever steel pipe scaffold system are simulated by COMSOL numerical simulation software. By comparing the results of numerical simulation and ultimate load test, the variation law of stress and vertical deformation displacement of the steel beam with the pull-up cantilever frame in the loading process is obtained, which provides necessary experimental and theoretical basis for monitoring and early warning of the pull-up cantilever scaffold.
