Experimental Investigation of the Durability of Load Bearing Timber-Glass Composites Under the Effects of Accelerated Aging

Abstract

Although timber was used extensively as a structural material for traditional buildings in Turkey in the past, usage of structural timber decreased significantly over time and timber has been largely replaced by other materials. As timber is a natural, durable and sustainable material, it would be desirable to re-introduce timber structural elements to contemporary construction in a form that is appealing to industry. Timber-glass composite structural elements are potentially a good candidate for this purpose. To that end, a series of tests were conducted on load-bearing timber-glass composites in order to understand the long–term structural performance of the composite material under atmospheric conditions; to decrease the recurring cost of repair and maintenance; and to minimize the exhaustion of raw materials and energy. In this paper, the first part of this experimental work is presented, which focuses on the durability of timber-glass composite under the effects of accelerated aging, carried out on small-sized timber-glass composite specimens. Accelerated aging effects were observed under wetting-drying, freezing-thawing, UV effects, resistance to acids and high temperature. The mechanical strength of the timber-glass composite specimens before and after the effect of accelerated aging was measured by adhesion and shear strength tests and a comparative analysis of the results was carried out. The results of the experiments indicate that timber-glass composite is suitable to be used under protection from environmental conditions.

“…Az építőipar technológiai kérdései különösen hangsúlyosak. A nagy fesztávú fafödémek felé támasztott elvárások (Nesheim, et al, 2021), a rétegelt lemezek jellemzői (Parsons, et al, 2021), a faanyag tárolási körülményeinek hatása a felhasználhatóságra (Vieira, et al, 2021), a szabálytalan alakú fűrészáru feldolgozhatósága (Aagaard & Larsen, 2020), a hőszigetelő, faalapú panelek jellemzői (Grohmann, et al, 2020), az axiálisan terhelt önmetsző csavarok felhasználhatósága (Brandner, et al, 2019), az alapanyag védelme a betegségek ellen (Gazis, et al, 2018) (Czaplicki, et al, 2016), a magas teherbírású fa-üveg kompozitok termelése (Buyuktaskin, et al, 2017), a fapadlók technológiai problémái (Kujawińska, et al, 2017), a faszerkezeti módosítások (Németh, et al, 2016), a faanyag biomasszaként történő hasznosítása (Goryunov, et al, 2016) mind-mind fontos technológiai kérdések, de nyilván gazdaságossági és fenntarthatósági vonatkozásaik is vannak.…”

Understanding structural health monitoring data to support decision-making processes and service life management of mass timber buildings. A preliminary study on use of data scaffolding

“…It can cause dimensional changes (i.e. shrinking and swelling), subsequently affecting building tolerances (Arda Buyuktaskin et al 2019), while also inducing internal stresses within a wooden member, which can lead to the propagation of cracks (Björngrim et al 2016; Franke et al 2018). High or fluctuating levels of MC can have impacts on the long-term deformation of structural timber elements, due to a combination of viscoelastic and mechano-sorptive creep (Grossman 1976; Muszyński et al 2005; Toratti 1992).…”
