Enhancing the Structural Performance of Masonry Arch Bridges with Ballast Mats
Publisher: American Society of Civil Engineers
Abstract: A large portion of the railway bridge stock in many countries is comprised of masonry arch bridges. During recent years, more attention has been paid to the maintenance of such structures. Rehabilitation and retrofitting ...
Dynamic Forces at Square and Inclined Rail Joints: Field Experiments
Publisher: American Society of Civil Engineers
Abstract: Insulated rail joints (IRJs) are widely used in signaling and broken rail identification systems. Track deterioration adjacent to IRJ is frequent due to excessive dynamic forces generated at IRJs by the repetitive passage ...
Effects of Wheel Defects on Dynamic Track Buckling in Transition Zones of Open-Deck Steel Bridges
Publisher: ASCE
Abstract: Track buckling potential can be higher in the transition zones of steel bridges due to the combination of contact loads and large compressive forces present in this region because of rail and bridge thermal loads. Wheel–rail ...
Transition Zones of Steel Bridges as Hotspots for Track Buckling
Publisher: ASCE
Abstract: Open deck steel bridges are characterized by the direct connection of transoms to the bridge girders. The expansion of steel girders due to thermal loads is transmitted by the fastening system to the track in the transition ...
