DESIGN OF CONTINUOUS CURVED BRIDGES

UNIVERSITY OF MARYLAND LABORATORIES HAVE DEVELOPED A SOPHISTICATED ANALYTICAL TECHNIQUE WHICH INCORPORATES INTERACTION OF ALL CURVED BRIDGE ELEMENTS. RESULTS OF THE STUDY INDICATE THAT THE PRELIMINARY DESIGN SECTION PROPERTIES ARE SUFFICIENT TO WITHSTAND THE DEAD AND LIVE LOAD EFFECTS, AND WILL NOT EXCEED DESIGN STRESSES. THE STRESS RESULTANTS DEMONSTRATE THAT THE DEAD LOAD WARPING CONDITION IS IMPORTANT AND MUST BE CONSIDERED IN DESIGN. GENERALLY, THE LIVE LOAD EFFECT IS NEGLIGIBLE. THE STIFFENING EFFECT OF BRACING CAN REDUCE THE TORSIONAL EFFECTS, AND THUS REDUCE WARPING STRESSES. A DESIGN TECHNIQUE FOR ESTIMATING THIS INFLUENCE SHOULD BE EXAMINED IN DETAIL. /AUTHOR/
