  • Preliminary in-plain shear test of damaged infill strengthened by FRPU [Elektronski vir]
    Triller, Petra ...
    This paper presents results of in-plain shear tests carried out in ZAG laboratory in Ljubljana (Slovenia) on a RC frame with masonry infill made of clay blocks (KEBEOrthoBlock). The frame fixed at ... the bottom and loaded vertically at columns’ tops was excited by horizontal cyclic loads at the top beam level. These loads forced various and gradually increasing drift levels (positive and negative) of the frame, with 3 repetitions at each level. Acquired forces andmeasured displacements allowed drawing hysteresis loops for determination of dissipation energy. Additionally, Digital Image Correlation (DIC) system was used for visualization of the behavior of the tested specimens. Three types of specimen were tested. The first one, the reference specimen in form of plain RC frame was forced up to 4.3% of the frame horizontal drift when significant crushing at the bottom of both RC columns occurred. The second one, the reference specimen with constructed masonry infill without any strengthening was forced up to 1.6% of the frame horizontal drift when crushing at the corners and complete detachment at the frame-infill interface occurred. The infillwould be destroyed even with small out-of-plane forces. In the third one step the damaged infill was strengthened on both sides using glass mesh bonded to the infill and the RC frame using flexible adhesive made of polyurethane matrix. This Glass Fiber Reinforced PolyUrethane (GFRPU) allowed withstanding additional cyclic loads, generating the maximum frame drift of the value 3.6%, without serious damages disqualifying the structure from further exploitation. The tested GFRPU strengthening system was very effective and resistant to out-of-plane forces (damaging infills in seismic areas).
