Effect of fire on FRP reinforced concrete members
Fire resistance of concrete members reinforced with fiber reinforced polymer (FRP) rebars is an extremely crucial area that needs to be investigated prior to implementing FRP composite materials in buildings and other fire vulnerable structures. This work examines analytically the performance of FRP reinforced concrete beams subjected to high temperatures.

Residual Shear Capacity of Reinforced Concrete Beams after
The mechanical properties of concrete and steel are seriously degraded under high temperature so that reinforced concrete (RC) members after fire may not be able to satisfy the prescribed performance. In this study 27 full-scale RC beams were carried out shear tests to investigate the shear behaviour after fire.
