Abstract
The performance and efficiency of two types of rigid pavements with contraction joints viz. Plain Cement Concrete (PCC) and Steel Fibre Reinforced Concrete (SFRC) are evaluated by nonlinear static analysis using the finite element software ANSYS. The ultimate load carrying capacity, deflection pattern, and load transfer across the joint for the three critical load positions - interior, edge and corner - on rigid pavements are investigated. Results show that there is significant improvement in the ultimate load carrying capacity for the SFRC slabs. Efficiency of joint with respect to load transfer and deflection is also found to be better for SFRC slabs.
