About Paper:

Concrete anchors, which allow structural and nonstructural elements to be attached to concrete, are vital in modern architectural design and are found in many common structures such as light pole fixtures, column-to- foundation connections, and facade installations. Due to these fasteners being developed relatively recently compared to more established construction methods, their behavior in certain situations still needs to be fully understood. This research aims to understand how concrete anchors and the foundation they are attached to behave when experiencing cyclic uniaxial moment loading. Various experiments were conducted to determine the performance of the anchors including load-displacement behavior and failure mode/crack pattern. The varied parameters include the distance from the edge of the concrete slab, the starting displacement direction, and anchor embedment depth. In addition, a corresponding static loading test was performed to allow for a comparison of static versus cyclic loading. Preliminary analysis shows the load capacity can decrease by up to 18% and the displacement at the peak load can decrease by up to 45% due to cyclic loading. These results will allow architects and engineers to better determine the effects that seismic loads can have on a structure. Further work involves conducting extensive numerical analysis and small-scale testing to characterize the influence of different parameters on the moment capacity such as anchor diameter, depth, and spacing.
