Abstract
This paper introduces the innovative technique in strengthening concrete compression members using the Post-Tensioned Metal Straps (PTMS) system. The PTMS utilizes high-strength straps to actively confine structural members. This prestressed steel straps are tensioned and wrapped around the structural members by using the simple strapping tools as those used in the packaging industry. The experimental results from literature indicate the success of PTMS in strengthening structural concrete members by increasing capacity and ductility of structures under seismic loads. Consequently, PTMS is considered the strengthening solution that is faster and more cost-effective compared to other traditional strengthening methods. This paper highlights and discusses the potential uses of PTMS in strengthening applications in Thailand.
