In our past webinar, Pankaj Shrestha of GM2 Associates, Inc. shared his experience on bridge load rating using Midas Civil. He demonstrated how to use Midas civil to model curved steel box girder bridges as well as go over the .The box girder normally comprises either prestressed concrete, structural steel, or a composite of steel and reinforced concrete. A box girder is formed when two web plates are joined by a common flange at both the top and the bottom. The closed cell which is formed has a much greater torsional stiffness and strength than an open section and it . The safety evaluation of single-tower steel box girder bridges over the sea includes various factors, including the steel box girder, concrete main tower, main cables, suspension rods and others . In addition, box girders offer an attractive appearance. The high torsional rigidity of box girders makes this type of construction preferable for bridges with curved girders. Also, the high rigidity assists the deck in distributing loads transversely. This is illustrated in Fig. 12.50. A single load placed off center on a bridge with single .
Steel box girder redesign of a two-span bridge resulting in large construction cost savings for the client. "The use of LUSAS helped us meet our design deadline and to prove an alternative bridge design that will ultimately save the client a great deal of money in construction costs."The failure of four steel box girder bridges during construction caused quite a furore. The use of such girders in bridge construction had been a fairly recent phenomenon, partly because the mathematical analysis was quite daunting before the advent of electronic computers. Their popularity came at a time when the post-war surge in bridge .
