Bridge Bearings Introduction AASHTO defines a bearing as a structural device that transmits loads while facilitating translation and/or rotation.1 In the past Caltrans has used a variety of bearings with varying degrees of success. These include rockers, rollers, pins, pots, steel girder hangers, PTFE/elastomeric, and elastomeric pads.
Economical Steel Bridge Design & Skewed Bridge Affected by plate length availability and economics of welding and inspecting a splice vs. extending a thicker plate Optimal ordered plate lengths usually 80 feet A welded I-girder flange splice is equivalent to 800 to 1,200 lbs of steel plate Three or fewer flange thicknesses per flange (or two shop splices) should be
Maximum rigid length 27.4 m (over 27.4 m requires a special order) Length of load A vehicle of rigid vehicle length over 18.65 m but less than 27.4 m (and within the limits of width, weight and axle load mentioned above) requires that notice be given to police. Any vehicle with rigid vehicle length over
