507 Modelling Analytical Frame Structure Using Parametric 108 Design K. Petersen DTU Civil Engineering, Technical University of Denmark INTRODUCTION Basic building structures such as steel frames are very common but depending on the context, they will have very different dimensions. Setting up the structural model to perform the structural analysis might be somewhat trivial but still very laborious to do. By performing the structural calculations, the use of materials can be optimized. Steel production for construction is 832 mega tons. Steel production emits roughly 1.8 tons CO2 per tons crude steel WS, so even a marginal reduction of use can have a great environmental impact. This project aims to automate the model setup for very basic structures in order to improve engineering productivity and improve structural optimizations. THEORY The concept of parametric design is to make an abstraction of a design that can be altered by manipulating various parameters. In this case a steel frame can be defined by five points that are connected by four lines. The relative distance between the nodes can be set up as parameters that can then be modified. Modifying the parameters will change the overall geometry of the structure. METHOD Using Autodesk Dynamo a visual programming interface to set up the geometry and Autodesk React Structures to perform the structural calculations an analytical model is set up. The model geometry is parametrically driven such that changes to for instance width, length or height will propagate to the analytical model. CONCLUSION The project has not been applied in a real world case, so there is no evidence that this will lead to more optimal designs or improved productivity. The concept can be extended to be used in architecture that is more complex as long as a geometric abstraction can be made. Especially architects would be able to exploit this concept greatly since they easily can test and explore various designs and at the same time perform a basic preliminary structural analysis, giving a competitive edge.
