Abstract:

During bridge construction, flexible support conditions provided by steel-reinforced neoprene bearing pads supporting precast, prestressed concrete girders may allow the girders to become unstable, rolling about an axis parallel to the span of the girders. Additionally, skew and/or slope angles significantly reduce bearing pads roll stiffness, which reduces girder buckling capacity under gravity and wind loading conditions.
