Abstract

Abstract

The steel spherical hinged support is in complex stress states subjected to various load combinations. In order to assess its mechanical properties and the influence on integral structural safety, taking the large support of T2 of Guangzhou Baiyun International Airport as an example, the numerical simulation analysis and full-scale model experiment for the shear properties of the support subjected to axial compressive load were carried out. It was indicated that the stress and deformation curves of experiments and numerical simulation results were coincident. The support was in low stress level. In addition, the relations between horizontal displacement and horizontal shear force was linear. On this basis, according to the test and simulation results, the fitted shear stiffness model of the support subjected to axial compressive load was proposed for the refinement mechanical analysis of integral structure.
