“…Construction solutions based on wood are a response to the sustainability trend. Modern ecological wood constructions can compete with traditional solutions based on concrete, silicates, steel and other conventionally used materials [34][35][36]. Wood is an ecological and renewable material, i.e., it is created in a natural process and perishes without negative effects [37].…”

In the construction industry, it is the material production phase and the use phase of buildings’ life cycles that represent the greatest environmental burden. The presented research focused on wood constructions during their use phase. The primary objective of the research was to determine the amount of CO2 produced during the operation of specific wood constructions in connection with the energy demand for their heating. A correlation analysis of selected parameters revealed a statistically significant correlation between heating medium type and energy demand for heating (p = −0.5773) and between heating medium type and amount of CO2 produced (p = 0.4796). A more detailed analysis showed that, in terms of the average energy demand for heating, the column constructions were the most efficient among the compared construction systems, regardless of the energy standard. Similar findings were obtained for annual CO2 production in connection with the average energy demand for heating. The only difference was that the panel and log constructions exhibited almost identical parameters, which came as a surprise to some extent. The column constructions turned out to be the most efficient again, regardless of their energy standard. The analysis that focused on the heating medium type revealed statistically significant differences among the heating medium types in energy demand for heating (p < 0.0001). The constructions that used electricity for heating were the most energy-efficient. When the individual characteristics of the different heating media in relation to CO2 production were taken into account, the constructions that were heated using biomass were the least polluting. The constructions heated using electricity and gas showed a significantly greater deviation.

“…CLT panel is a building material made from several layers of spruce wood which is, according to Wieruszewski and Mazela (2017), distinctive by several positive properties. As stated by Frangi et al (2009), dried spruce boards are placed across each other and individual layers are glued on the complete surface area.…”

The paper deals with testing fire resistance of a vertical wooden building construction made of CLT panels subjected to the medium-scale test of the fire resistance. A model test of fire resistance with the ceramic radiation panel as the radiation heat source, with achievable temperature of radiation surface of 935°C at maximum was used. The aim of the experiment was to assess the experiment sample whether it meets the request of the thermal insulation and integrity under thermal loading of the model fire for 30 min. The test resulted in the increase of temperatures on observed thermocouples and assessment of the integrity on the unexposed side of the CLT panel. The construction clearly resisted the effects of the radiation heat during 30 min and maintained the observed criteria of fire resistance. Charred layer of the CLT panel created on the surface of the exposed side in the thickness of 20 mm inhibited the heat transfer into the further layers of construction.

“…A madeira, material natural renovável e de fácil obtenção, é a matéria-prima mais antiga adotada em construções. Devido à sua ampla disponibilidade na natureza e relativa facilidade de manuseio, tem sido usada pela humanidade ao longo da história, atendendo atividades humanas habituais, como superar obstáculos, transporte, moradias, entre outros (CHRISTOFORO et al, 2013a;ARAUJO et al, 2016;WIERUSZEWSKI;MAZELA, 2017;ALMEIDA et al, 2018a).…”

Relações entre propriedades de rigidez para distintas solicitações mecânicas visando projetos de estruturas de madeira

et al. 2020

Resumo No Brasil, o documento normativo NBR 7190 (ABNT, 1997) estabelece os métodos de ensaio para obtenção das propriedades físico-mecânicas da madeira. Na impossibilidade da determinação dos resultados experimentais, a norma estabelece relações entre propriedades. Porém as relações entre as propriedades de rigidez apresentadas foram determinadas com base no antigo referencial normativo MB-26:1940 (NBR 6230), que considerava outro modelo de cálculo e não ao utilizado pela norma brasileira. Nesse contexto, este trabalho objetivou investigar a equivalência entre os módulos de elasticidade na flexão (EM), compressão (Ec0) e tração (Et0) paralela às fibras de dez espécies de madeiras tropicais, assim como de estabelecer correlações adequadas entre tais propriedades em caso de não equivalência. Os resultados da ANOVA acusaram que Ec0 e Et0 são estatisticamente equivalentes, o mesmo não ocorreu entre EM e 0,90∙Ec0, implicando a determinação do coeficiente ótimo de 0,98 pelo método dos mínimos quadrados. Tal coeficiente mostrou ser 8,89% superior ao apresentado pela norma brasileira.
