The bridge design by planning a detailed calculation of the various structures, physics. To select the material to be used to create a bridge that was better, and you can wave and wind storms continue. Planned duration in creation. To calculate the area of the lane of travel and transport. Measurement of climate and water depth. Need to explain that the superstructure using prestressed concrete beams and forms the image is divided into several pieces in 1 span construction, we will install the girder bridges with steel frame sliders with multiple names, launching girder truss beam launcher, launching, where there are several such systems, overhead or underslung in the installation that we cancel the bridge beams and parts, then make a move, comes a full span, splice. Then do the stressing in this structure, each tendon prestressed concrete system will be pulled.
