Abstract

The present study aims to evaluate the influence of the modulus of elasticity of concrete in multi-floor buildings. Initially four simulations were carried out with the aid of TQS software for a 30 storey building, altering in each one only the type of aggregate (basalt, granite, limestone and sandstone). It was observed that the lower the modulus of deformation of the concrete, the greater the displacements and second-order forces acting on the structure. Next, a comparison was made in terms of overall stability between NBR 6118: 2014 and NBR 6118: 2003. It was verified that the structures executed before the revision of this norm may be exhibiting a behavior different from that predicted in projects. Sequentially a study of the variation of material consumption was carried out so that simulated structures with different types of aggregate presented the same coefficient γz, altering the sections of the pillars in the simulated structures with aggregates that give the concrete a smaller modulus of elasticity. There was an expressive increase of concrete, forms and steel in the pillars, a small reduction of these inputs in the beams, and uniformity in the slabs. Finally, a comparison was made between a scaling of the compressive strength of the concrete, decreasing the same along the pillars, in relation to the use of a single class of resistance in a structure. It has been verified that this alternative proves feasible, and can generate a reduction of a structure"™s costs of.
