Comportamiento Estructural de Cubiertas Tipo Tenso Membranas Empleando el Método de Elementos Finitos

Structural engineering over time has been dedicated to the search for increasingly lighter systems and materials, thus finding theso-called tensile membranes or lightweight structures based onstructures that combine membranes and steel cables becoming theoptimal solution to cover spaces that human activity requires on a daily basis. In this article is analyzed the behavior of three different forms of tensile membranes with the same span of 17 m, applying the FEM finite element method with the help of computational packages such as SAP2000 and ANSYS Workbench, starting with a pre-design of elements taking as a reference theload stresses of the NEC-2015 and ASCE 7-16 standards, resulting in stress concentrations in the main support regions in the arch type models, deformations and resistance variations with critical values in the hyperbolic paraboloid type membrane in the central region with a value of 216 MPa due to the design of the cable-type support structures of the membrane, evidencing the deficiency in the transfer of stresses in the existing supports.
