Researchers' Work from Graz University of Technology Focuses on Numerical Modeling (Advanced Numerical Simulations for Prediction of Bearing Capacity and Failure of Complex RC Structures)
By a News Reporter-Staff News Editor at Journal of Mathematics -- Investigators discuss new findings in Numerical Modeling. According to news reporting from Graz, Austria, by VerticalNews journalists, research stated, "Advanced numerical simulations using computers provide a robust tool for assessing the structural integrity of existing reinforced concrete (RC) structures. This paper presents an application of modern computer simulation, in the context of nonlinear finite element method (nonlinear FEM), to predict the load-bearing capacity and failure behavior of different types of RC column-slab connections strengthened by steel profiles in an existing complex industrial RC structure in Austria."
The news correspondents obtained a quote from the research from the Graz University of Technology, "Two typical connections are subjected to primary numerical investigation using nonlinear three-dimensional FEM with a newly developed constitutive model for concrete. Subsequent verification tests indicate that the primary numerical analyses are quite consistent with the test observations. Post-numerical analyses of the verification tests are also carried out taking into account the measured material properties. The simulation results are in very good agreement with the test data. Based on the numerical results, the load-flow mechanisms and the load-sharing portions in the connections are identified. The ultimate loads of the rest of the connections are then determined using numerical analysis, hence no further tests are necessary."
According to the news reporters, the research concluded: "On the basis of the numerical simulations, rational decisions on the structure are made."
