Behaviour of post-installed adhesive anchors in concrete for crane-supporting structures

In steel structures, anchor bolts with steel base plates connect steel columns to concrete foundations. These anchors may experience different types of loading, including tension, shear, or combined shear and tension. There are two installation methods for anchors in reinforced concrete: cast-in-place anchors for new construction and post-installed anchors for existing structures. While research on cast-in-place anchors is extensive, studies on post-installed bonded anchors under different loads are limited, especially for crane-supporting columns attached to existing slabs. This research aims to critically investigate the performance of post-installed anchors in concrete foundations, including reinforced concrete slabs, under different types of loading. The effect of different parameters, such as the embedment length of the anchor, anchor spacing, anchor diameter, minimum edge distance of anchor, and thickness of column base plate, on the performance of anchors will be investigated. The findings from this proposed research will be crucial for the partner organization as they are currently seeking guidelines for installing their crane structures in existing building slabs. The results of this research will benefit structural engineers and the steel construction industry in Canada. Furthermore, this project will provide training for an intern in structural engineering and nonlinear finite element analysis.
