Abstract

In this article the behavior of cooling towers under progressive collapse using the finite element method\ninvestigated. The nonlinear material properties of concrete and nonlinear geometry were considered in the finite element\nmodels. Alternative load path and deferent dynamic condition were proposed to improve the prospective of cooling towers\nbehavior under progressive collapse, to achieve this aims different size of rings on the top of columns were utilized and the\ncolumn(s) which is removed have been eliminated with deferent speeds. The models were validated and used to perform\ninvestigating different parameters affecting the behavior of cooling towers under progressive collapse. The investigated\nparameters are comprised of different size of rings utilized and different dynamic conditions. As the results the progressive\ncollapse potential decreased as the thickness of ring increased and the residual deformation decreased as the thickness of ring\nincreased in both types of collapse.
