Comparação entre um edifício em alvenaria estrutural projetado sem o uso de softwares e com o TQS Alvest

Abstract

Masonry is one of the oldest construction systems in the scientific literature. It is extremely efficient, which enables reduction in costs, optimization of time, and it allows a cleaner and more eco-friendly construction site when compared to the conventional system. The objective of this present research is the comparative study of the calculation and design of a masonry building by a skilled professional without the use of software to the calculation and design using TQS software. It was emphasized the consideration of the arching effect on the software, in order to conclude if the existence of this parameter in the projects, realized in a simple but systemic way by a computational program, would be able to reduce construction expenses in concrete volume and steel weight, compared to the increase in expenses in stronger masonry blocks. After analyzing the results, several advantages of the software design were perceptible when compared to the manual design. TQS has an easy-to-understand platform and it presents a more agile and more reliable design and detailing. The software also analyzes the arching effect with excellence, confirming its viability. After its consideration in the project, there was an increase in the expenses with the masonry blocks in the floor of approximately 16.09%. On the other hand, it was possible to reduce approximately 42.57% in the expenses in concrete volume in the beams on the transition floor. Therefore, it is possible to conclude that the reduction in concrete volume compensates for the increase in the masonry blocks strength. For didactic purposes, a standard dimension was adopted for the sections of the beams and, also, the initial grouting utilized in the manual model was not altered, although, in real projects, it is possible to enable even more this reduction without the exorbitant increase in the masonry blocks strength.
