【 摘 要 】

In order to improve the compressive behavior of existing brick masonry walls, one of the most commonly used strengthening techniques is to use steel strips fixed on the masonry walls by the binding bolts, which has the advantages of easy construction and short construction period. Under axial compression, the criteria for judging the failure of strengthened masonry walls is that the masonry walls reach the peak strain or steel strips occur critical local buckling. Based on the stress-strain curves of the brick masonry wall and the steel, the axial compressive characteristics of brick masonry wall strengthened by steel strip is discussed, and a simplified formula to predict the load-carrying capacity of this type of strengthened walls is proposed and calibrated by collecting experimental results.
