Introduction— The construction of box girder bridges has increased in recent years in Colombia. Some previous studies have shown the significant effects in the results due to omission of the construction process, the rheological properties of the materials, and the environmental conditions can generate significant effects on the results. Due to the variety in the different territories of Colombia, it is interesting to determine the effect of these conditions on the structural response of the bridge.
Objective— The main goal of the study is to quantify the variations in the structural response of the main elements of a post–tensioned box girder bridge, during construction and in service, due to changes of the relative humidity of the environment.
Method— A computational model of a representative Colombia bridge studied was developed in the software Midas Civil. The model includes the time–dependent effects of the materials. Three different (extreme high, medium, and extreme low) values of relative humidity were used in the analysis.
Results— The variation in the longitudinal bending moment, shear and axial forces, and the deflection of the girder, and those of the columns bending moment were calculated by varying the relative humidity of the environment.
Conclusions— Negligible variations in the structural response of the bridge elements during construction after modifying the relative humidity. On the other hand, some elements (especially the girder) responses showed sensibility and considerable changes due to modification of the environment parameter.
