文摘

Infills made of bricks which are free to slide along bed joints suffer very little seismic damage. A viscous filler in joints is vital for gas/water-tightness and thermal/acoustic insulation. To follow the shear distortion of infills, openings need articulated frame corners and tolerances. Infills without mortar go unscathed through earthquakes inducing interstory drifts over 5.5%. A rail-in-groove system along the brick’s top and bottom faces works against out-of-plane collapse. Infills without mortar collapse out-of-plane at deflections of about 75% their thickness.
