This project will investigate the possible use of a high strength synthetic fiber (Kevlar) to reinforce bridge columns externally by wrapping the fiber around the column while being tensioned. This technique will prestress the column to provide additional ductility, stiffness, and strength.

该项目将研究使用高强度合成纤维(芳纶)对桥柱进行外部加固的可能性，方法是在张拉时将纤维缠绕在桥柱周围。这种技术将对柱施加预应力，以提供额外的延性、刚度和强度。
