• Abstract:
  The overall goal of this project was to improve the safety and sustainability in the design of large ; prestressed concrete bridges and other transportation structures. The safety of large concrete ; structures, including bridges, has been insufficient. This is evidenced by the worldwide rate of failures ; of very large concrete structures which has historically been about 1 in a thousand per lifetime, ; although 1 in a million is the maximum tolerable. Improvement necessitates taking into account the ; size effect on quasibrittle failure loads, a phenomenon that has been mostly ignored by the ACI code ; committee until recently, but now is considered seriously, largely as a result of this project.
