Soluções estruturais para pilares de divisa: análise e dimensionamento em software comercial

Abstract

When the architectural design of a building on the border of a land is elaborated, the pillar is facing this border, so, as a structural solution, a foundation must be used that does not advance into the neighboring land, and the most common alternatives for this case are: eccentric boundary footing without beam, eccentric boundary footing with lever beam (balance) and boundary footing with transition beam (cantilever). With the aid of the TQS software, modeling was carried out in residential building, with two floors, for the three alternatives, as well as their analyses. Some difficulties were found in the software to dimension and attend the verifications for the first alternative, resulting in large dimensions for the boundary footings, this being an unfeasible solution for the building, due to the proximity that the footings are, and the ground may come to break due to bulb stresses. As for the other two alternatives, the software presented consistent results for the building in question. Overall, the TQS is satisfactory for the design and analysis of boundary footings.
