• Abstract:
  This study investigated sizes and geometry of existing bridges in Colorado and investigated standard bridge systems used by ; other entities. The study proposed standard bridge types advancing the goals of SHRP 2 R19A & B, the rapidest ABC ; construction, and encompassing a wide range of span and structure lengths and widths, with the capability of a wide range of ; skews while preserving, to the extent possible, simplicity, low construction cost and a competitive contracting environment, ; in order to achieve the largest practical benefit to Colorado’s bridges over the coming decades. For Colorado these are pre-decked simple made continuous precast girders, and shaft and precast cap substructures, all made integral with details ; emulative of CIP construction. These are made practical by an effort to control camber and camber variations by design and ; by monostrand post-tensioning camber adjustment. ; Implementation is planned to be progressive, starting from worksheets for standard superstructures and substructures in ; conjunction with prototype structures, expanding to encompass more acute skews, and finally, additional worksheets ; incorporating the design information to accommodate the full range of anticipated structure types, spans, span arrangements, ; and skews without additional detailed structural design or details for each individual bridge element. At this time, a worksheet ; can be developed to allow simplified presentation of the desired structure. Minor organizational changes are proposed to ; ensure continuity of the development and maintenance of these worksheets. Rough estimated implementation costs and value ; of benefits are included.
