Estudio de cimentación tipo zapata corrida para pórticos con muros estructurales de concreto en edificaciones

Abstract

This paper deals with the study of continuous footing-type foundations for gantries with concrete structural walls in buildings in Machala, a city with high seismic activity and alluvial soils of low bearing capacity. With the main objective of evaluating the behavior of these foundations in the face of additional loads generated by the incorporation of structural walls, proposing an optimal design that adapts to local geotechnical conditions. The methodology used integrates a documentary and experimental review, which includes structural modeling carried out with specialized software, analysis of soil properties and regulatory studies based on the NEC and ACI 318-19. Likewise, simulations were carried out to evaluate the stresses and differential settlements in various foundation scenarios, considering multiple buildings both with and without the incorporation of structural walls. The results indicate that structural walls considerably improve the stability of buildings, reducing lateral drift and settlements. However, the need to strategically locate them and make adjustments to the foundations to avoid failures due to critical soil conditions is emphasized. Therefore, an adequate design of continuous footings, based on soil structure interaction, is essential to ensure an efficient and safe distribution of loads in the buildings of Machala.
