The use of structural steel profiles as an external shear bracing is one of the most preferable simple, time saving and cost-efficient strengthening method for an inadequate existing reinforced concrete (RC) structure against earthquake lateral loads in comparison to the other interrupting, irritating and destructive traditional in plane strengthening methods which need evacuation of houses. With the use of this method, inhabitants of building can continue their daily life as usual during the strengthening site work. With this experimental study it is aimed to determine the shear performance of anchor bolts used to connect the steel lama to an RC single span frame depending on embedment depth. For this purpose, a special steel construction loading system has been designed and constructed and six RC column-beam frames are prepared and five of them were strengthened using steel lama connected to the frame with different numbers of anchors in different depths. And also an equation was found related with the shear performance of steel anchor bolts depending on the anchor embedment depth.
