Analysis on the Collision Couple between Drift Ice and Long-Span Prestressed Concrete T-Rigid Frame Bridge Pier

Abstract:

Long-span bridge across the river in cold areas, is often impacted by the drift ice in spring, thus having some severe effects on the stability and vibration of the bridge structure. With a long-span prestressed concrete T-rigid frame bridge as studied object, based on the display analysis function of the LS-DYNA software, this paper represents the simulating process of the contact and collision between the drift-ice and T-rigid frame bridge pier, and the influence of various factors was analyzed, such as model boundary condition, contact types of river ice and pier, algorithm and element connection transition area. Thus the reasonable calculation model of the collision force caused by drift-ice to pier was determined. The result has important theoretical and practical value to ensure the safety of the bridge in cold area, as well as to reduce the project cost.
