Steel has already developed steel plates commercially which satisfy the JISSM570TMC standard with air-cooling after plate rolling57).Because the cooling rate dependence of the microstructure is small in extremely-low carbon bainitic steel,strength deviations in the plate thickness direction are slight,and the plate results for this questionHow thick should bottom tension flange be?How thick should bottom tension flange be?For bottom flanges,plate distortion during fabrication and erection can be a problem.Check with fabricators when using bottom tension flange plates less than 1 inch thick to determine whether practical stiffness needs are met.Bottom tension flanges should never be less than 3/4 inch thick.Reference results for this questionWhat is fabrication and erection tolerance?What is fabrication and erection tolerance?Fabrication and Erection Tolerances The AISC Specification for Structural Steel Buildings,the Code of Standard Practice for Steel Buildings and Bridges,AWS D1.1 and other existing specifications and codes cover tolerance re- quirements for the fabrication and erection of structural steel.AISC Home - steelwise results for this questionWhat is the appropriate tolerance for welded cross section?What is the appropriate tolerance for welded cross section?The appropriate tolerances for a welded cross-section are specified in AWS D1.1 Clause 5.23.However,at bolted splic- es for such members,this AWS information is silent on this subject.AISC recommends that the permissible deviations for girder depth given by AWS D1.1 be applied to depth at bolted splices as well.AISC Home - steelwise

10 Bridge Bearings Design Guide for Bridges for Service

Bridge super- structures experience translational movements and end rotations caused by traffic load- ing,thermal effects,creep and shrinkage,wind and seismic forces,initial construction tolerances,and other factors.Bridge bearings are designed and built to accommodate these movements and rotations while supporting required gravity loads Accuracy of steel fabrication - SteelConstructionfoSpecial tolerances.Individual projects may specify special tolerances,either as a modification of the essential or functional tolerances or for aspects not already covered.There is a need for certain additional tolerances on most bridge structures,and these should generally be implemented via the Specification for Highway Works.Bridge Bearings - CaltransBridge 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.
