Item Acesso aberto (Open Access) Análise da vida útil e o custo de reparo de fachadas de edificações verticais(Universidade Federal do Pará, 2020-02-28) VELOSO, Thiago Pinheiro; MAUÉS, Luiz Maurício Furtado; http://lattes.cnpq.br/7497951647889934; https://orcid.org/0000-0002-1762-8617The façades of buildings have frequently presented levels of degradation higher than desired in recent years, exposing problems related to quality and durability, characterized by premature aging due, above all, to the appearance of pathological manifestation. Such complications cause several problems, affecting use, aesthetics, safety, and above all the durability of the buildings. With the advent of the Performance Standard (ABNT, 2013), it was possible to create durability parameters for all elements of a building, from the definition of durability terms in three levels: minimum, medium and maximum. In this sense, we sought to evaluate the usefull life of vertical building facades, as well as the frequency with which intervention occurs is them, the cost of repair, as well as a simulation was performed in the software “simulates v 4.4”. From the data collection with the application of a form in a company of great representation in the sector of façade repair, it was possible to account for 40 buildings with signs of dregacy. These buildings were divided into two groups taking into account the intervention time after delivery, that is, a group comprised between 1 and 7 years and another group between 8 and 15 years. With the adoption of the “simula v 4.4” software, based on the Monte Carlo method, cost and time simulations were carried out, aiming to determine the number of interventions required to manintain these facades, as well as the cost for such, in a cycle of 50 years. The results presented show that Group I had a lower performance than Group II in both situations, requiring more repair actions and a higher execution value, considering a minimum, medium and maximum reference generated by the program. In addition, the figures obtained show that both groups are below the minimum durability term recommended by the standard, which is 20 years, beyond the average and maximum terms, which are 25 and 30 years respectively, confirming the presence of a series of factors that interfered in the process of design and execution of the these facades. Thus, it is concluded that special attention should be given in the assembly of the facades of the buildings, as they are a very expensive component of the work, and that add a lot of value to the final product.
