Análisis económico entre cimentaciones losa maciza y "T" invertida

Abstract

The present work analyzes two types of foundations: salid slab and inverted "T" with the objective of establishing which ofthe two structures is the most econornical for a 6-story building located in the city of Azogues in a consolidated area, following technical specifications, factors and coefficients of the Ecuadorian Construction NEC-15 and the criteria of the A.C.I. Code 3 l 8S-l 9. Through the use of Cypecad software that will allow us to know previously the functionality of the structure, evaluate the criteria of torsion, basal shear, centers of mass and floor drift. Our analysis allows us to discern and show that the technical criteria such as: floor drifts, torsion, settlements, stresses on the ground do not vary greatly between the foundation alternatives studied, therefore, at a technical level both proposals meet the same service standard. At the economic leve! we found a considerable difference in pnces, the solid slab foundation is 41,205.28 USD and the construction cost of the inverted "T" beam foundation is 30,080.96 USO. A difference of 11,124.32 USD, 36.98% of the cost of the inverted "T" beam foundation. Therefore, it mm is feasible to use the inverted "T" beam foundation alternative, since it is more economical. is it concluded that
