AASHTO GSWLB-1, Guide Specifications for Wind Loads on Bridges During Construction, First Edition (2017), establishes minimum requirements for wind loads on bridges during construction before a deck is placed. Section 4 defines exposure conditions, including wind speed, wind direction for determining wind exposure category, ground surface roughness categories, and wind exposure categories. Wind loads are then specified separately for the superstructure and for the substructure. Control of wind-induced bridge motions is addressed through peak wind-induced motions and the control of dynamic responses, so that girders, temporary and permanent bracing, and substructure elements can be checked. All other aspects of design follow the LRFD Bridge Design Specifications or the requirements of the bridge owner. The specifications are intended for bridge designers and contractors planning erection and construction sequences.
