Research Start Date:
July 1, 1995
Expected Completion Date:
October 31, 1996
Research Objectives:
Large accelerations in a severe earthquake may force a pier wall to experience force levels beyond the elastic range, causing substantial localized damage. Instead of demolishing the damaged pier wall and building a new one, it may be beneficial to repair the damaged wall resulting in substantial savings in material and labor along with a quick restoration time to its intended use. The main objective of this research is to repair damaged pier walls from a previous Caltrans testing program and to compare the strength, ductility and cross-tie performance of the repaired walls with the undamaged pier walls. Six damaged pier wall samples will be used to test the effectiveness of proposed repair techniques. Each repaired sample will be cyclically loaded as in earlier investigations.
Expected Products or Deliverables:
Design recommendations for the repair of earthquake-damaged pier walls.
