Post-fire behaviour of continuous reinforced concrete slabs under different fire conditions

An experimental investigation of the performance reinforced concrete continuous slabs is presented in this paper, following exposure to different compartment fires. The influence that several factors, including fire scenarios, reinforcement ratio, and bar arrangement, have on deflections, strains, crack patterns, failure modes analysed. Results compared uniform case, localized or extended punching shear are more likely occur fire-damaged subjected traveling due cracks. residual structural stiffness ultimate loads enhanced with increasing reinforcing but brittle readily appeared. Finally, deflection criterion (l/50) ACI 318-08 theory helpful predicting any scenario.
