Application of PP-ECC in beam–column joint connections of rigid-framed railway bridges to reduce transverse reinforcements

In the rigid-famed railway bridges, due to extensive amount of transverse reinforcements in the joint connections, the over congestion at the connection brings the difficulties in fabricating and casting. With the objective of avoiding the congestion, Polypropylene Fiber Reinforced Engineered Cementitious Composite (PP-ECC), as one kind of Engineered Cementitious Composites, was implemented to reduce the extensive amount of transverse...
