Longitudinal steel bars are provided to resist the tensile forces in the bottom of the beam due to bending (or flexure). • All bridge connections are made with either pins or bolts and there is no need for any specialist tools such as pneumatic or electric powered tools. There is more to design than calculating the forces in the structural members and proportioning the sections. 5 meter span; 14 days for underside of slab, beams, arches above 4. In many instances, prestressed concrete is used, which combines high tensile steel with concrete to create an incredibly strong beam. The aim is to determine the optimum spans lengths for continuous beams under dynamic loadings considering the involved cost elements.
