This special publication is a compilation of existing articles on various structural strengthening, stiffening, and stabilization topics, including external bonded reinforcement, external post-tensioning, internal post-tensioning, section enlargement and overlays, supplemental framing and span shortening, and strengthening and stabilization of masonry structures. The purpose is to provide engineers and contractors with a single-source overview of the various materials and techniques available to solve strengthening, stiffening, and stabilization problems. The wealth of information provided should provide invaluable “food for thought” to facilitate the strengthening, stiffening, and stabilization design process.
