KLEINGESINDS, S. E. Influence of the arch effect consideration on the loadbearing structure cost for structural masonry buildings. 2014. 181 p. Thesis (MSc) – Escola de Engenharia de São Carlos, Universidade de São Paulo, São Carlos, 2014. This work deals with the assessment of the potential economic benefit that the consideration of the so-called arch effect can provide to the design of support reinforced concrete structures for structural masonry buildings. After a literature review, some theoretical fundamentals on the studied subject are presented and three real building cases are studied using the Finite Elements Method. For each building case, two different numerical models are used: the regular one, without the arch effect, and the model that takes it into account. When the arch effect is considered, the regions subjected to compressive stress concentrations are checked in order to verify the structural safety. As for the support beams, the internal forces are obtained and the beams are dimensioned considering both the described numerical models. Then the obtained results are compared, focusing on internal forces, displacements and consumption of materials. Finally, for each studied case and for both numerical models used the construction costs are evaluated and compared in order to demonstrate the benefit of the arch effect consideration.
