Abstract
The deformations and stresses in a typical bridge bearing have been evaluated by testing a three dimensional photoelastic model, supported upon a flexible foundation. This investigation has revealed the form of the pressure distribution on the foundation, and provides quantitative values for the bending stresses and fillet stress concentrations in the bearing pot base. Attention has been focused on the deformation mechanism which induces a significant all round tension in the pot base. This confirms the importance of the interaction between the base and rim, and provides the information necessary to develop a realistic analytical model of the bearing.
