Residual shear crack width and shear drift component havebeen studied on six beam specimens. The ratio between Σ_(i=1)~n W_(hi) and δ_s for R≤1.00% and R≤2.00% are 76%-108% and 59%-82% respectively. Compared to higher residual drift, the crackgauges picked up shear drift component better at lower residualdrifts.
