Impact of Construction Loads on Steel Diaphragm Bridge Design

The objectives of this research are: (1) To understand the loads on steel diaphragm bridges during the construction process through visual observation of bridge construction. (2) To measure the effect of construction loads on steel diaphragm bridges during construction via sensors. (3) To quantify the construction loads on the structure using the observations and measured data combined with computational and analytical models. (4) To draft recommended practices (e.g., construction loads) for Georgia Department of Transportation (GDOT) steel diaphragm design. (5) To recommend a standardized GDOT steel diaphragm designs based on the appropriate loading conditions, span lengths and beam types.
