Diseño y modelación de diafragmas metálicos en acero al carbono

Abstract

Structures are made up of several parts, one of them being rigid diaphragms, which are structural elements that support loads in the direction of the force of gravity, which helps the structure not to deform and to have a better behavior in the face of external forces. As a consequence, in the present study, rigid diaphragms were modeled and fabricated to be used as mezzanine floors in buildings. The models were subjected to load forces per unit area, measuring the maximum deflections reached and internal forces that these generate in the different points of support, achieving as a result the design in comparison to the tests does not differ in the deflections, a small comparison of two steel structures was made, one made of slab with collaborating panel and the other with the analyzed rigid diaphragm, knowing the maximum value of overload that can be applied in the element so that its deflection remains in the appropriate range depending on the separation of supports. A decrease of up to 50 % of the total weight of the structure was observed with the rigid diaphragm system compared to traditional steel structures.
