Diseño de cimentaciones aisladas y losas de cimentación, en una edificación de 4 plantas para comparar los métodos: rígido y elástico, con el uso del programa informático SAFE

Abstract

This technical project is based on designing isolated foundations and foundation slabs of a structure, using: the rigid and elastic method through manual calculations and the SAFE program in order to make an economic and technical comparison of the amount of steel, concrete sections, costs and determine the advantages or disadvantages of using each of the methods. In all civil engineering projects, one of the most important aspects to be taken into account is the optimal design of the foundation, so it will be verified if by using the rigid method we will obtain larger dimensions due to the fact that it is a simplified model or if by the elastic method that considers the deformability of the support layer or the relative stiffness of the soil between the supporting soil and the foundation will generate foundations with smaller dimension sections. In the analysis, two models were developed in ETABS in order to obtain the loads for the respective design of the isolated foundations and foundation slabs by the rigid method, the design was carried out through manual calculations in electronic sheets and the elastic method in the SAFE program, through two types of soils: soft and dense with admissible stresses of 1 kg/cm² and 3 kg/cm² respectively, in this way the results of both methodologies were compared, with regard to the economic proposal and execution times elaborated in the PUNIS program, the amount of steel and volumes were also considered, complying with the NEC-2015 and ACI 318S-14 regulations
