Determinación experimental de coeficientes m y k para planchas metálicas de espesores 0.65, 0.76 y 1 [mm], con diferentes espesores de hormigón y dos diámetros diferentes de malla electro-soldada corrugada, sometida a cargas de flexión monotónicas y cíclicas : Ensayo de deck metálico de 1[mm]

Abstract

With the aim of meeting new construction requirements and obtaining better information about market materials, as well as seeking improvements in structural designs, this current work is being conducted to study the behavior of a composite system slab. It aims to determine the coefficients 'm' and 'k,' corresponding to the nominal strength and composite stiffness, respectively, using 1 mm thick metal plates reinforced with 6 mm diameter welded wire mesh. This determination will be made through the application of a test where the composite system of metal plate and concrete is subjected to both monotonic and cyclic loads. The test to be applied is based on the methodology described in the standard (T-CD-2011 Test Standard for Composite Steel Deck-Slabs, 2011). This methodology involves applying a concentrated linear load on composite slab specimens, with standardized dimensions, at different points along the length between the supports on which the simply supported slab rests. From this test, the failure point of the specimen and the load at which it fails will be determined. Subsequently, data analysis will be carried out to obtain characteristic 'm - k' values. The entire process will be carried out in the outdoor facilities of the Center for Housing Research (CIV) at the National Polytechnic School and in the CIV laboratories. Finally, the 'm-k' design method will be used to determine the shear stress in the interaction zone (steel sheet - concrete), performance curves, and the maximum flexural resistance force or failure force of each tested specimen.
