Q1: If Sb, is the average bond stress on a bar of diameter d subjected to maximum stress t, the length of the embedment l is given byA ![]() B ![]() C ![]() D ![]() E ![]() ANS:D - The length of embedment (l) required for a bar subjected to maximum stress (t) and average bond stress (b) on a bar of diameter (d) can be determined using the relationship derived from bond stress equations. The embedment length is crucial for ensuring proper bond between the reinforcing bar and the surrounding concrete. One commonly used relationship to calculate the embedment length is provided by the following equation: l=Sb×π×d2/4*T Where:
