Isogeometric Analysis for Modeling and Simulation of Building Processes

Isogeometric analysis provides the fundamental features for a fully CAD-integrated design process. Simple further processing of simulation results is enabled and therefore perfectly suited for the simulation of a building process. This is especially useful if slender (bending-active) structures with highly flexible components and large deformations are part of the simulation. Here, the consideration of construction stages plays a crucial role. This contribution presents essential aspects of an isogeometric building process, and reveals its benefits and challenges. Structural isogeometric analysis together with its basis functions (NURBS) is briefly introduced. The special issues of building processes are emonstrated. The essential feature of coupling within the construction is presented and further extended to an automatic connection between two points. In the end, several modelling aspects w.r.t. suitability of the NURBS patches provided by CAD for structural analysis are outlined.     «
