Parametric Study of Seismic Performance of Steel Bridges Pier Rehabilitated with Composite Connection

Connections pipe pile to cap beam in steel bridges have important roles on structure strength affecting lateral loads such as earthquake. One of the most important strategies are to translate plastic hinge from connections to the other places in structure. In this study four types of composite steel...
