dc.description.abstract | During the lifespan of timber buildings, structural members may exhibit different defects and/or
failures. This may include splits that develop due to shrinkage because of changes in the moisture
content of wood and/or due to excessive flexure bending, tensile, or shear stresses. To rehabilitate
timber structures, there are various retrofitting techniques used to strengthen damaged wood
members. Some of the available methods include the utilization of fiber-reinforced polymer
wrapping sheets, mechanical fasteners such as self-tapping screws (STS), and glued-in rods. The
utilization of STS was proven to be the most economical and easiest retrofitting technique. In
ambient conditions, this technique has been shown to greatly increase the strength of wood-steel-
wood (WSW) connections when subjected to flexure bending. STS have also been shown to
significantly increase the ductility of timber beams utilizing such reinforced connections. Although
STS have proved to be very effective in enhancing the strength of glued-laminated timber (glulam)
beams with WSW connections in ambient conditions, there has been very minimal research on the
effect of STS on retrofitting glulam beams with such connections in fire conditions. [...] | en_US |
