This study proposes a parametric modeling method for efficient design in early step of FCM (Free Cantilever Method) bridges which has variational section. Parameters for forming longitudinal shape of box girder are defined, and then constraints and functional relation between the parameters are defined according to some design guidelines and statics of parameters in existing FCM bridge designs. In addition, the relations between longitudinal shape and placing rebar are defined. Some case studies are demonstrated to show how to model the sample bridge with the constraints and relations by changing only one or a few parameters. Finally, material quantity of the sample bridge model generated by parametric modeling is calculated and comparing to real quantity to validate the accuracy of the model by parametric modeling. |
