Development of load-bearing shell-type trc structures – initial numerical analysis
Abstract
<p>In nature, shell structures can be found in diverse variations. Compared to straight beams, where the bending stress increases disproportionately due to its weight, shell structures can handle significantly larger spans with minimal material expenditure. In the ideal case, only membrane stresses prevail in such thin-walled structures. To reach a similar performance in structures made of textile reinforced concrete (TRC), one of the aims is to develop an analysis method and software solution appropriate for the design routine of thin-walled structures. This goal is realized by adopting the software Rhino 3D in combination with the programming environment Grasshopper 3D. Together with the utilization of commercial FEM software, this method provides access to an integration of failure criteria selected for the analysis purpose within the scope of the project. Additionally, potential shortcomings of the commercial software regarding material modeling and appropriate failure criteria for TRC can be investigated and overcome by a collaboration between scientists in experimental, design and computational subprojects of the CRC/TRR 280 which is devoted to new design strategies for carbon reinforced concrete structures. Firstly, one attractive constitutive model is the microplane approach. The formulation at hand combines damage and plasticity to model concrete in a realistic manner. Concrete initially behaves isotropically, from which anisotropy develops under increasing load. The model used in this contribution overcomes the downside of mesh dependencies by using a non-local damage formulation. This method also ensures a reliable convergence of the applied Newton type solver for the global system of equations. Secondly, the Multiscale Projection Method is capable of handling localization effects like cracks in shell-like structures. Crack initiation and propagation can be simulated introducing a phase-field method for fracture to the fine scale. This approach allows the detailed simulation of the mesoscale cracking behavior, which is significant for the overall failure of the macroscopic structure.</p>
