Curved glass plates are used as curtain walls in modern buildings for architectural requirements, which makes them exposed to wind load pressure. In this research, an experimental test and finite element analysis are carried out to investigate the behavior of curved glass plates under uniform pressure loads. Thin curved aluminum plate was tested simulating a monolithic glass plate due to the similarity of modulus of elasticity and Poisson’s ratio inboth aluminum and glass [1]. In order to simulate a uniform pressure loading on the tested plate, an enclosed chamber was manufactured as a supporting system for the tested plate which was glued with the chamber usingstructural silicon sealant. The internal air in the chamber was sucked out to simulate the positive pressure on the outside surface of the tested plate. Displacement transducers and strain gauges were mounted on the tested system to measure the displacements and strains as the pressure was reduced inside the chamber. Numerical sensitivity analysis was made using ABAQUS 6.14 software to find out the suitable element type and support conditions that could simulate the experimental model. Results of analysis were presented and discussed. It was found that the 8-node solid element could not represent the curved plate. On the other hand, 20-node solid element could simulate curved glass plate but showed higher failure load. The best element that could simulate the thin curved glass plate is found to be shell element in the current study
