The present study focuses on the mechanical response of concrete columns confined with fiber-reinforced polymer composites (FRP). Practical columns often deviate from axisymmetric conditions due to noncircular cross section, geometric imperfections, and loading eccentricities. This paper discusses these complicating effects on the mechanical behavior of columns confined with FRP. Experiments have been carried out to examine the effects of geometric and loading imperfections on columns of various shapes. A model originally developed for axisymmetric situations has been extended to include the complicating effects. An analytical study for the corner radius that avoids concentration of stress is carried out. The theoretical models have been verified with the present and published experimental results.
