Comparativo entre sistema de losa de entrepiso con Metaldeck vs BubbleDeck y Metaldeck vs losas alveolares para un centro comercial en Samborondón.

Abstract

In this study, a comparison is made between the Metaldeck floor slab system and two other concrete slab systems known as Bubbledeck and hollow core slabs, the first being a concrete slab lightened with polyethylene spheres and the second a precast and prestressed concrete slab lightened by means of longitudinal hollows. Taking as a case study the shopping center "Buijo City Center", for which Metaldeck has been used, a new design with Bubbledeck and hollow core slabs is carried out to determine which of these systems has a better performance when comparing structural, and economic parameters. Therefore, the structural drawings are modified, and models are created in the SAP2000 finite element program to define the new beam sections, the amount of reinforcing steel and to be able to analyze the values of deflections, moments, and shear. With the defined designs, the amount of material used is calculated and unit price analyses are performed to determine the final budget for each slab system. Comparative tables of structural behavior and costs are prepared to analyze which of these systems is the most convenient for the construction of the shopping center and also describe in which cases the implementation of each type of slab can be beneficial.
