Investigation on the behaviour of prestressed concrete sleepers (PCS) under negative static loading

Abstract Railways in Malaysia are undoubtedly a various incorporated element that can possibly assume as an imperative part in the advancement of a manageable transportation framework in the nation. Therefore, failure of prestressed concrete sleepers under the negative static loading need to be investigate due to its role as one of the important part in railway. In this study, negative moment test was established to investigate the design load of the prestressed concrete sleeper (PCS) under negative static loading. Three (3) samples of PCS were used and one (1) PCS contains two rail seat, called KTMB and EPMI sides. It is found that new crack appeared on EPMI sides with the length of 100 millimeters. Meanwhile, the highest displacement for EPMI and KTMB sides were found to be 7.332 and 6.606 millimeters. From three (3) samples tested, only one PCS shows the failure to cater the design load of 176.94 kN subjected to rail seat.
