  • Seismic behaviour of multistorey strengthened Urm Masonry Shear Walls With Openings [Elektronski vir] : an experimental study
    Triller, Petra ; Gams, Matija, gradbeništvo ; Tomaževič, Miha
    To research the efficiency of technologies of strengthening of earthquake-damaged masonry buildings built from hollow clay block, an assemblage of three-storey full scale plain masonry shear walls ... has been tested after strengthening it by fibre reinforced polymers (FRP). Constant vertical load, typical for residential building was applied by means of a hydraulic system. Seismic loads, acting cyclically at the floor levels, were applied in the form of a linear force pattern along the height. The walls were first tested in unstrengthened state up to the occurrence of considerable damage (beyond maximum resistance limit state) and then strengthened by a system based on FRP coating. After that, the walls were retested until collapse. Because the collapse and damage occurred on the first and second floor, respectively, an additional test of only the top floor was performed. The results of the tests show that adequate strengthening solutions provide significantly improved seismic behaviour. If properly applied and anchored, the coating and the wall act together as a composite material and respond in shear.
