Determining Bond-Slip Characteristics of Prestressing Tendons with Varying Geometries in Two Concrete Mixtures
Keywords: Track, ties, concrete, bond-slip, prestressing tendons
Abstract: Untensioned pullout tests were conducted to obtain the bond-slip characteristics of two groups of prestressing tendons used in concrete railroad tie production. The purpose of...
Keywords: Concrete crossties, water damage, center cracks, cyclic loading
Abstract: To investigate the impact of moisture on crack growth and other tie damage, UIUC researchers subjected pretensioned concrete crossties and small-scale beams to repeated loading...
Keywords: Friction, friction management, lubrication, vehicle-track interaction, wheel-rail interaction v
Abstract: Friction has a huge influence on the vehicle/track interaction and yet it remains poorly understood, its consideration an afterthought in many simulation activities. This survey...
Keywords: active noise control, active vibration control, static operation, on-track operation
Abstract: This project evaluated the performance of active noise control (ANC) and active vibration control (AVC) technologies using a GP40-2 locomotive located at the Transportation...
