SUMMARY:

Ceramic clad facades are widely used in commercial and residential buildings due to their durability, weather resistance and attractive aesthetics. Over time, these facades are subject to different factors and agents that can cause anomalies and degradation, affecting their appearance and performance. Different degrees of protection and exposure to agents of degradation, as well as the variability of the quality of materials and construction processes lead to a differentiated degradation along the facade. This work presents an analysis of the variability of degradation in facades with ceramic coating, with the objective of investigating how it presents itself, its quantification and which factors are responsible. The aim is to understand the behavior of degradation in the different positions of the façade plan, exposing how it manifests itself in terms of the floors of the buildings and the regions of the samples on the façades. We seek to identify different variables that have the potential to explain the degradation process and the most vulnerable points of the façade, allowing the development of adequate maintenance and rehabilitation strategies. The research starts from a database, developed from inspections in buildings in use, using the Degradation Measurement Method (MMD). The methodology is applied to the study of 174 samples of facades of six-story buildings, aged between 5 and 48 years old and located in Brasília, Brazil. The analyzes are based on degradation indicators, such as the General Degradation Factor (FGD), quantified from the investigated variables. Subsequently, statistical tools are applied to investigate the variability of degradation. The results allow the identification of degradation variability in relation to the proposed variables, as well as typical patterns of degradation in the façade plane. There is variability in degradation between the floors of the building, especially in relation to the top, the floor with the highest rates of degradation and the highest frequency of damage. Central region presented degradation variation in relation to the extreme regions.
