MUNOZ, Edgar; GOMEZ, David; NUNEZ, Federico y FLOREZ, Carlos. Genetic algorithms and instrumentation determination of dynamic loads of heavy trucks over a bridge. Rev. ing. constr. [online]. 2011, vol.26, n.3, pp. 321-352. ISSN 0718-5073. http://dx.doi.org/10.4067/S0718-50732011000300005.
This research determines the axle loads of trucks traveling on a bridge located in one of the most important corridors of Colombia, using the technique of control BWIM (Bridge Weight in Motion), not used before in the country. Our research group developed a Genetic Algorithm based in a trial test, implementation and monitoring to the bridge called Boquerón of Colombian Highways (Bogota - Villavicencio). For such an effort, four girders were monitored by data acquisition electronics joined by an electronic traffic log device by lane accompanied of laboratory testing for materials. Model calibration was performed by mathematical approach of in-situ influence lines compared to those obtained by modeling, giving as outcome loads of moving trucks over the bridge. In addition, we developed a computational tool, able to represent with reasonable accuracy the moving loads.
