This paper presents the results of an experimental investigation on the anchorage of deformed steel bars embedded in bed joints of masonry. The effect of bar diameter, anchorage length and vertical load on the mortar joint is investigated. Although the horizontal bars in masonry are under unfavourable conditions, such as low strength of mortar, small cover values, lack of bond at places where the bars pass over large holes of the masonry unit, tests have proved that embedment lengths as low as 30 to 40 times the bar diameter seem to be sufficient for the bars to develop their yield strength.
