This paper shows a reliability analysis evaluation of the main frames of one of the most important Colombian bridges. The evaluation was carried out by employing the following techniques: geometrical detailing, mechanical tests, traffic counting, load deformation tests, structural calibration of the bridge model, instrumentation, electrical monitoring and numerical simulation. The monitoring procedure was implemented by a series of electronic sensors connected to the main frame bridge structure in multiple locations to measure and record data from the strain gages sensors. The purpose for employing the monitoring procedure described above was to compile real-time data to compare them with the design load (C-40-95) established by the Colombian Seismic Code of Bridges Design. Overloads were found in some of the monitored frames. This fact compromises the bridge’s safety and stability and must be controlled immediately. Additionally, probability failure calculations were carried out and the results were that the structure safety ranges that assure stability and a lower risk condition were not found. |
