The provided shear key joints are practically unreinforced due to their small size, and performance directly affects the structural behavior of segmental concrete bridge. In addition, these usually dry distributed over contact region between two connected bridge parts. current research examines effect lateral confinement pressure (1, 2, 3, 4, 5, 6) MPa elevated temperature values (23, 200, 400, 600) °C on single dried tested under concentrated static loading using Nonlinear Finite Element Analysis (NLFEA) procedure. simulation models were first validated experimental data from literature compared ultimate deflection, load, cracking propagation, failure modes ABAQUS software, where available Concrete Damage Plasticity model was utilized. Twenty-four simulated different combinations parameters included in parametric study. Results reported terms load-deflection behavior, characteristics, propagation within zone, final modes. It has been found that initial stiffness, strength all increased increasing pressure. Moreover, situation is totally when exposure exceeds 400 °C. Finally, a new formula introduced for predicting capacity after being against numerical sets, along with design codes standards. A very good agreement reached proposed mathematical equations.
