[3], defined first some of the parameters involved in the design of a bridge with girders, such as: a) live load, b)the type of girder, c) the strength of the concrete slab and the strength of concrete in the girder and 639 Abel Noé Xochicale Cortés Acta Polytechnica CTU Proceedings Figure 2.	cache/app01-8043.pdf	txt/app01-8043.txt
