Constant Amplitude of Prestressed Concrete Sleeper (PCS) Subjected to Three Coaches Train

Investigation on simulation of train loading on prestressed concrete sleepers

Railway concrete sleepers have been developed and utilized in railway industry for over 50 years. Cyclic loading because of vibration on sleepers due to the train loading and the velocity of train itself and also a small percentage of bad wheels, can eventually lead to a crack network and failure of component. The objective of this study is to investigate the load carrying capacity of the selec...

Prestressed Concrete Piles

A state of the art presentation on prestressed piling as used throughout the world is discussed in this General Report to the FIP Symposium on Mass-Produced Prestressed Precast Elements in Madrid, Spain, May 1968. Historical information, design data and notes along with manufacturing techniques, installation practices, discussion of problems and failures and a complete bibliography are all cove...

Ductility of Prestressed and Partially Prestressed Concrete Beam Sections

D analyses of structures responding elastically to ground motions recorded during severe earthquakes have shown that the theoretical response inertia loads are generally significantly greater than the static design lateral loads recommended by codes. Hence, structures designed for the lateral earthquake loads recommended by codes can only survive severe earthquakes if they have sufficient ducti...

Ductility Evaluation of Prestressed Concrete Members

In this paper, moment-curvature behavior and ductility of prestressed concrete members based on nonlinear analysis is investigated. Influence of various design parameters on ductility of flexural members is determined according to appropriate materials models for stress-strain curves of concrete, prestressing steel and conventional reinforcements. Parameters studied include reinforcing index (ω...
