“…The action of these fungi only affects wood aesthetics due to discolorations or stains ( Fig. 1A), which may be superficial or deep; however, they significantly reduce the quality and the commercial value of wood (BLANCHETTE, 2000;COELHO et al, 2007;BRITO, 2014). In other words, staining fungi have little ability to deteriorate wood constituents (SILVA et al, 2014).…”

Wood is rich in organic compounds; thus, it is susceptible to attacks by several deteriorating agents because they acknowledge such attacks as a necessary energy supply. Fungi stand out among these agents since they can attack the wood in trees (before felling) and in several post-felling stages. Fungi are biological agents that use organic compounds as food sources, and that is the reason why they degrade most chemical components found in wood. Wood attacked by fungi suffers significant value loss, since these degrading agents affect their mechanical and aesthetic properties. Fungi — which are classified as staining, molding and rotting — are one of the main responsible for the biggest losses in the timber industry. Wood can be virtually used in a whole range of environments, a fact that makes it susceptible to attacks by different fungal species, since the ideal conditions for fungal development change from species to species. In other words, the fact that one or more fungal species are capable of deteriorating wood is directly related to conditions wood is subjected to. Thus, it is essential knowing how to evaluate fungal attacks, symptoms to be taken into consideration at the time to identify the type of attacking organism and the attack stage, as well as the control and prevention measures to be applied to these organisms.

“…The wood is an amazing combination that exhibits both strength and durability as a structural material used for roof structures. Nevertheless, from the time it is formed in the tree, wood is subject to deterioration by a variety of agents biotic and abiotic [3,4,5,11]. Damage ranges from relatively minor discolorations caused by fungi or chemicals to more serious decay and insect attack [4].…”

“…The main methods that are available for inspecting timber structures, normally do not require sophisticated tools. These methods, which include visual characteristics by visual inspection technique; sounding with hammer; probing test; pick test with mortise chisel; measuring moisture content by moisture meter; and microdrilling by Resistograph, for example, may be used singly or in combination [3,4,6,7,11].…”

This research presents the assessment of historic structural systems timber roofs type "Hauff" of constructions existing in Poços de Caldas, Minas Gerais, Brazil. The large timber structures originated with the engineering company "Hauff", whose production of timber structures contributed in great measure to the technological advance of the industry of construction engineering with wood in Brazil. Based on photographic by techniques of visual inspection (NDT) and descriptive documentation, this paper offers examples of timber roof structures that constitute most of type "Hauff" roof structural systems, such as, lamellar roof structure, sawn lumber nailed arch, plywood arch, shed truss roof, that were built between the years 40 and 60 in the city at Poços de Caldas in Minas Gerais. The timber structures with "Hauff" were built in various regions of Brazil at that time.

“…As propriedades mecânicas da madeira apresentam grande importância, tanto que a utilização deste material na construção civil é muito comum para diversas finalidades, desde a confecção de componentes de edificação como portas, batentes e esquadrias, até elementos estruturais como pilares e vigas. O emprego da madeira em fôrmas e cimbramentos também ocorre com elevada frequência (BRITO, 2014;ALMEIDA et al, 2018).…”
