Modelling of fastener flexibility in CFRP strengthened timber-framed walls using modified ▫$\gamma$▫-methodPremrov, Miroslav, 1967- ; Dobrila, PeterThe paper provides semi-analytical modelling for prefabricated timber-framed walls using the modified ▫$/gamma$▫-method. The walls are composed of a timber frame and gypsum plasterboards (GPB) which ... are flexibly connected to the timber frame. Because the tensile strength of the GPB is approximately 10-times lower than the compressive one, it is convenient to strengthen the boards in their tensile diagonal direction with carbon fibre-reinforced polymer (CFRP) strips, which are glued to the boards. Additionally, in the proposed mathematical model the classical beam theory is used taking into account a fasteners' flexibility in the timber frame - GPB connecting area, as well as crack appearing in the GPB and an influence of the inserted CFRP strips. Therefore the CFRP strip contribution is considered with a modified slip modulus which results in the fictive increased stiffness coefficient of the fasteners.Source: Engineering structures. - ISSN 0141-0296 (Vol. 30, iss. 2, 2008, str. 368-375)Type of material - article, component partPublish date - 2008Language - englishCOBISS.SI-ID - 11312918
