ULTIMATE STRENGTH AND STRAIN OF CONCRETE STRUSTS IN IN-FILLED WALL PANELS OF FRAMED SHEARWALLS

摘要

A new loading apparatus which can simulate the stress condition of cracked wall panels in framed shearwalls was proposed. By using the apparatus, the loading tests on the concrete strut specimens which were reinforced by either the orthogonal grid reinforcement in longitudinal and transverse directions or that in 45 deg direction were conducted. The shear strength of the wall panels observed by the tests agreed well with the shear strength of wall panels in framed shearwalls whose lateral load carrying capacity was dominated by the slip shear failure.
