Experimental Study of Infill Walls with Joint Reinforcement Subjected to In-Plane Lateral Load

The results of an experimental study four infilled frames with brick masonry walls subject to reversal cyclic lateral load are presented. variables studied were the height length aspect ratio wall and use joint reinforcement. investigation was motivated by fact that Mexican code establishes same specifications about reinforcement for infill as confined walls, because there is not enough evidence on reinforced walls. To investigate possible interaction in seismic performance two pairs specimens, scaled 1:2, different ratios (H/L = 0.75, 0.41) tested. specimens each pair identical except one them included steel bars into bed-joints leading amount phfyh=0.6 MPa. H/L 0.41 from a previous study. behavior defined terms strength, ductility, displacement capacity, deformation crack pattern. indicate increases strength system; however, increase more pronounced longer Ductility reduced horizontal this important As occurred generates distributed cracking reduces width cracks. experiments described other discussed detail.
