• Abstract:
  The study outlined in this report aimed to quantify the available redundancy in pony truss bridge systems ; constructed using standard designs and practices in the state of Ohio. A method of conducting refined ; three-dimensional nonlinear finite element analyses that can be used to assess the level of redundancy ; in bridge pony systems was developed and used to study the performance of pony truss bridges. It was ; found that when they are properly detailed and constructed, deck systems in pony-truss bridge can be ; inherently redundant. To a lesser extent, it was also found that truss members in properly designed and ; constructed bridges can also be redundant.
