Experimental evaluation of the effect of different design conditions on the risk of decay in solid wood exposed to outdoor climate

Abstract

Wood decay have the greatest impact on in-service wood structural elements. In most cases, decay is associated with excessive accumulation of moisture in the wood. The structural design conditions have an effect on the wood moisture content and this affects the service life of the material. In this study, which involved an experimental trial specifically designed to embrace different structural design conditions, the moisture content evolution in different places affected by different design conditions was evaluated over a period of three years in Madrid (Spain). The effect of protection by eaves, separation from the ground and the vertical or horizontal arrangement of the wood elements on the monthly evolution of the moisture content and decay risk are assessed.

Degradation of Mechanical Performance of Hoop Head Tenon-Mortise Joint of Tusi Manor with Decay Disease in Tibetan Areas in Yunnan

“…To study the effect of decay on the degradation of mechanical properties of wood, scholars have conducted a series of studies in the past [16][17][18][19][20], and it was found that the degradation of the mechanical properties of decayed wood was directly proportional to the decay cycle, and many of the mechanical properties of the wood degraded significantly after treatment with a shorter decay cycle, but the majority of these studies were carried out through the decay test of small test specimens. Wang and García, among others, investigated the degradation patterns of the mechanical properties of wood under different artificial decay treatment methods [21,22]. Mi, Yang, and colleagues directly tested the mechanical properties of degraded wood obtained from ancient buildings.…”

Barreras para introducir madera maciza en la construcción en Ecuador – estudio exploratorio

“…Por eso, se recomienda hacer uso de prácticas que aíslen los elementos de la humedad como: el uso de aleros, superficies que absorban el agua, mecanismos para evitar la acumulación de agua en casos extremos de humedad y la separación de los elementos estructurales de madera del suelo. Todos estos factores pueden aumentar significativamente la vida útil de la estructura [21], [31], [25].…”
