An Advanced Spherical Bearing Model with FEA Analysis

The mechanical properties of spherical bearing have a direct influence on the seismic performance of bridge construction. Aiming at QZ12500GD spherical bearing, Abaqus finite element analysis software was used for modeling and analysis, and vertical pressure, horizontal thrust and vertical tension were analyzed to study the deformation and stress of the bearing. The model parameters and modeling method of spherical bearing in finite element software analysis are obtained. The analysis results show that this kind of bearing form has good deformation and bearing capacity under the design bearing capacity, and meets the design requirements.
