This paper presents the results of various research which has permitted a better understanding of steel box girder bridges and the development of design criteria. Through use of these design data, more efficient and rapid design of such structures can be achieved, and a better service to the public provided.
A box girder bridge, or box section bridge, is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises prestressed concrete, structural steel, or a composite of steel and reinforced concrete.
This design example illustrates the design calculations for a curved steel I-girder bridge, considering the Strength, Service, Fatigue and Constructability limit states in accordance with the AASHTO LRFD
A box girder bridge is one in which the principal structural element is one or more closed cells, acting in bending. Box girders are used for highway bridges, railway bridges and footbridges – different structural forms are chosen for each of these applications.
It is a bridge in which the main beams comprise girders in the shape of a hollow box (rectangular or trapezoidal shape). The box girder normally comprises either prestressed concrete, structural steel, or a composite of steel and reinforced concrete.
Two curved steel box girder bridges were completed in late 2003 approximately 18 miles east of downtown Seattle. The steel box girder structures were selected because of their fast erection over Interstate-90, tight horizontal curvature and no construction support in the environmentally sensitive creek below the structure. Major design ...
steel box girder is becoming more popular now as used in conjunction with cable supports in the cable stayed bridge. AISC's Design Manual for Orthotropic Steel Plate Deck Bridges was based upon the German developments and is the design reference used for these bridges in this country and elsewhere. The first major orthotropic steel plate deck ...
‘Western Region’ standard box girder bridge system in many situations where construction depth is very tightly constrained. Indeed, the standard designs have recently been updated to conform to design to the Eurocodes. Why choose steel box girders? The selection, or otherwise, of a steel box girder always needs a consideration of the
Steel Box Girders. Box girders have a clean, uninterrupted design line and require less maintenance because more than half of their surface area is protected from the weather.
A box girder bridge is a type of bridge where the primary structural element is a box-shaped girder. This girder typically comprises steel or reinforced concrete and features a hollow rectangular or square cross-section.
