Abstract

Mechanisms such as soil-structure interaction (SSI) and Construction Sequence (CS) are increasingly used to the detriment of models that consider columns as fixed node supports. It occurs that for a correct analysis of SSI and CS is fundamental a satisfactory prediction of settlements. This work aims to compare the effects of several settlement prediction methods on the SSI, and consequently, compare their effects on the distribution of axial forces and bending moments in a reinforced concrete building whose foundation is constituted by continuous flight auger piles. At the same time, the work aims to compare the efforts obtained with the use of CS in a fixed columns support model, with the model that employs the CS associated with prescribed displacements of the columns. Settlements predictions were carried out using methods established in the literature and according to the Brazilian standard. Prescribed displacements were obtained as a function of the building settlement monitoring. The results showed that settlement predictions can vary significantly from one to another. Furthermore, it was noticed that some columns presented behavior contrary to the expected when the soil-structure interaction is used, because when considering the referred mechanism, the expectation is that central columns reduce their load while the peripheral columns increase theirs. The use of the classic model, that is, Columns considered as fixed nodes, as well as the consideration of models that include SSI, can result in efforts of very different magnitudes, leading to uncertainties that are reflected in the safety of structures and foundations.
