Desenvolvimento de uma rotina computacional para fundações direta submetida a momentos fletores

Abstract

Direct foundations are a common type of shallow foundation in which the load is applied to the soil, predominantly by the pressures distributed under the base of the structural element. They are frequently used in buildings, where they play a structural role in the uniform distribution of loads to the underlying soil. The choice of the type of foundation depends on several factors, including the nature of the soil, the magnitude of the loads and the local conditions. Calculating the estimates at the base of the foundations is essential to ensure the safety and stability of these structures, and computational tools can assist in this calculation process. This work focuses on the development of a routine capable of analyzing direct foundations subjected to bending moments, with the objective of calculating the contact stress. The CALCPAD software, which has a simple programming language, has proven to be effective for this analysis. This study developed a computational routine and acquired the importance of computational tools in assisting the design of foundations, providing greater precision and efficiency in the process of dimensioning and structural analysis. For this purpose, 4 illustrative examples were made using the developed script and the results were compared through manual solutions found by abacus, in the case of circular geometry, and table, in the case of rectangular. The results obtained showed that the software was successful in its task, providing accurate analyses for both types of foundation.
