Análisis comparativo de capacidad portante para una estructura en la ciudad de Guayaquil

Abstract

This thesis addresses the fundamental issue of bearing capacity in geotechnical engineering, focusing on the design of shallow foundations, specifically double eccentric footings, in the geologically complex context of Guayaquil. The city is characterized by remarkable variability in its soil conditions, which poses significant challenges for the accurate prediction of bearing capacity and the safe and economical design of structures. The main objective of this study is to perform a comparative analysis of the allowable bearing capacity for a model structure, evaluating its behavior in five different soil profiles representative of Guayaquil. The proposed methodology includes the characterization of the geotechnical properties of these soils, the application of classical bearing capacity theories and the effective area method for eccentric loads, the verification of failure and service limit states, and the evaluation of the influence of factors such as the water table and seismic loads according to the Ecuadorian Construction Standard (NEC). The findings of this research will reveal how the geological diversity of Guayaquil affects the distribution of pressures and the stability of eccentric footings, providing crucial implications for safer and more efficient design practices in the region.
