Description
Bridge Falsework is a vital step in building a permanent bridge. Different loads and mass moments of inertia directly effect the deflection of stringer I-beams, which is the greatest indicator of vertical load strength of bridge falsework. Experiments were done to three different I-beams the W24x68, the W30x124 and the W36x300. Results found in simulations done in SolidWorks found that all beams passed the dead load minimum requirements but the W24x68 did not meet the live load requirements for the concrete box girder in question. The W30x124 I-beam would be the best choice for this design due to its strength and cost ratio.
