Calculated using the bridge, the bridge structure design, establishment of single edge beam model, application of load transverse distribution coefficient of principle, the spatial force transformation model of plane model is reasonable, single edge beam stress. Because of the most adverse side beams, beam side girder steel beam configuration is safe. Through the use of bridge modulation beam and shear module, to complete the edge beam steel beam position adjustment and shear design. Similar design of cross beam and girder design. Because the carriageway plate is simple in calculation, the use of hand complete. Finishing will be calculated data into account, drawing design drawings.
