Análise e dimensionamento de estacas em concreto armado sujeitas a solicitações laterais.

Abstract

The present work aims to present a study and analysis based on experimental calculations, so is possible to perform the dimensioning of reinforcement for piles subjected to lateral solicitations. This study involves a bibliographical review, referring to several methods proposed for calculating the requests to which the stakes are exposed. Two distinct cases were analyzed, one taking into account a reinforced concrete pole of circular section with a diameter of 50cm, which is contained by a clayey soil, whereas the second case takes into account a precast reinforced concrete pole, also of section circular with a diameter of 23cm, which is contained by a sandy soil. From the review, it was adopted the method of calculation proposed by Titze, so it was possible to perform the dimensioning of the reinforcement for the stake, were also analyzed two other methods to obtain the requests in the stake, the model of bars, which it was used the Ftool program, and the Finite Element Method using the Ansys program in its academic version 16.1. After obtaining the results the work analyzed the differences obtained through each method. It is concluded that there are variations between the different types of methods to obtain the requests, and that more detailed studies must be realized in order to obtain more accurate results in precision in the dimensions that are realized for the use of stakes subject to this type of request.
