After fire exposure, five slabs were strengthened using two or three layers of the strengthening systems.
Details of an experimental program investigating the structural performance of unreinforced masonry (URM) walls strengthened using two different types of polymer textile reinforced mortar (TRM) is presented.
Glass may be strengthened using one of several processes: temporarily reducing the severity of flaws by fire polishing or "etching" (i.e., chemical polishing); introducing surface compression by overlay glazing, thermal tempering, or ion exchange; and toughening by lamination.
Advanced reinforcement: The roof was strengthened using two cables, whose specifications were the same as the upper roof.
(b) Advanced reinforcement: The roof was strengthened using two cables, whose specifications were the same as the upper roof.
This paper investigated the fatigue behavior of six cracked steel beams strengthened using CFRP laminates via two approaches, i.e., sole adhesive bonding and adhesive bonding together with mechanical anchorage.
Thus the deck sections (one unstrengthened, and two strengthened using FRP composites) were subjected to routine traffic prior to removal and testing.
The testing matrix consisted of one un-strengthened beam and four beams strengthened using NSM CFRP rods prestressed to effective strain values of 0, 3260, 6899, and 9177 μ representing 0%, 20.4%, 43.1%, and 57.4% of the CFRP rod ultimate tensile strain, 1.6%.
Four beams were tested, a reference beam without CFRP, and three beams flexurally strengthened using different percentage of laminates.
One specimen was used as the control beam without any strengthening and six were strengthened using either the EBR or the EBRIG methods.
