EXPERIENCIAS EN SIMULACIÓN POR MEF DE ELEMENTOS LINEALES DE HORMIGÓN MEDIANTE LA HERRAMIENTA ATENA

Abstract

Modelling of concrete is a very important advance for optimizing structural elements, since it allows to simulate the expected behaviour for elements which will be manufactured and determine the weakest points on the design with no needing of preliminary tests or small scale models. Due to the complex and heterogeneous characteristics of the concrete behaviour, research on the material models adapted to the real response of the concrete is getting more advanced. In this way, ATENA commercial software has been specially developed to perform nonlinear FEM analysis on concrete elements in an easy way. This communication summarizes experience using ATENA for analysing different lineal elements of structural concrete on the ETSIAM de Albacete. Thereby, different models of a)reinforced, b)pre-stressed, c)recycled concrete elements has been performed to compare the behaviour on real experimental tests with the modelling results. This comparative allows contrasting and calibrating ATENA for different concrete structural situations. Results of the models show a very good fit to the experimental results and also determine the most important values to calibrate the material models on each situation.
