Abstract

Abstract: A method to strengthen a stone spandrel arch bridge was presented according to the damage situation of the bridge. The mechanical characteristics of using reinforced concrete fringe frame to strengthen stone masonry construction was also discussed. The simplified calculation method was presented. The analysis and comparison of the structure stress state before and after reinforcement were carried out aiming at bridge engineering.

Key words: spandrel, damage, reinforced concrete, frame structure
