Abstract
Existing reinforced concrete (RC) buildings designed prior to the 1970s are vulnerable to shear failure of beam-column joints under earthquake excitations because of insufficient transverse reinforcement in the joint region. The failure of such unreinforced joints, especially corner joints, has played a crucial role in building collapses in past earthquakes. The accurate prediction of shear strength and flexibility for these unreinforced beam-column joints is therefore essential to assess the seismic risk of older-type RC buildings characterized by having unreinforced beamcolumn joints. To predict shear strength, two shear-strength models were developed previously, as a part of this larger study. A practical shear-strength model combining the two previously developed models is presented in this report. No abstract available.
