Dimensionamento e detalhamento de pilares-parede

Abstract

In the last years the structures of the concrete buildings have changed a lot, mainly in the height of the buildings and in the slenderness of the structural parts. As consequence, the structural engineers start to concern about the displacements of the structures since the structural parts didn’t have the same hardness that it used to have. The pillars are structural elements which have a relevant function in the security of the structures made of reinforced concrete, as besides receiving the vertical loads coming from the slabs and beams and transferring those to the foundations, the pillars also resist to the horizontal loads, as the loads exercised by the wind, for example. Those pillars which resist to the loads exercised by the wind are called substructures of bracing, and in their majority are presented as pillars-walls that are used not only in the stairwell and lift case but also in whole structure. So, in this work a simplified formulation for the sizing and detailing of the reinforcement of the pillars-walls is presented through Excel’s spreadsheets considering the methods proposed in the NBR 6118:2003. In this work, the sizing calculated in the way is compared to the sizing and detailing obtained through the software CAD-TQS.
