Lifeline design of bridges

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


An analysis and design procedure is presented for retrofitting steel girder bridges that may experience the loss of a pier or column. Multispan and continuous grider bridges are treated. Pier failure or collapse can result from earthquake, scour or floods. The additional loads, resulting from pier failure, are resisted primarily in bending. The retrofitting scheme ensures that the bridge will not totally collapse but will still carry its own weight plus a specified portion of the design live load and resulting impact loads. There will be large deformations and cracking, but no loss of life.
