Parametric bridge design – reinforcement design

Abstract

Using BIM technology for the design process in the construction industry has become somewhat of a standard approach. For bridge design, various solutions offering geometric design functionality and data management facilities are available on the market. However, integrated solutions for seamlessly supporting the whole planning process are still a scarce commodity. The solution presented integrates architectural modeling, structural analysis, and sophisticated proof checking functionality in one package, where, based on a 4D architectural model, an analysis model is automatically derived, allowing for simulating the erection process in detail and investigating all relevant stress states. The focus of the paper is the reinforcement design of prestressed concrete sections, which is one of the most challenging tasks among the various requirements arising in the design process.
