Influence of Column Construction Type on the Bearing Capacity of Bonded Anchors

AbstractThe anchorage formed by the post-installed steel chemical anchors can be used for new buildings. Thanks to easy and fast installation can be used particularly for reconstructions. Chemical anchors are the most frequently used with concrete and reinforced concrete. On the trade of anchoring, the chemical anchor systems are represented by a number of variants of this anchorage type but, in fact, they always consist of a steel bolt (anchor) installed in a pre-drilled hole. The connection between a steel bolt and concrete or masonry (most frequently) is done by glue, i.e. usually by different types of epoxy.The research presented in this article is focused on a possible application of these anchor types, namely in the connection of a steel beam with a face plate to different types of columns.The analysis of a connection steel beam cantilever stressed by bending moment to the construction of the column with bonded anchors. The loading capacity of anchors connected (bonded) to steel HEB concreted column will be compared to loading capacity of anchors bonded to reinforced concrete column.Comparisons will be done on the basis of experimental tests and subsequently validated by numerical models. Compared resistance of the anchors is different for columns and the rigidity of joints
