Masonry columns strengthened with bar mesh highly ductile fiber reinforced concrete (BMHDC) jacket under concentric and eccentric loads
Highlights The effectiveness of HDC system as a means for reinforcement of masonry was studied. The BMHDC jacket improved both load bearing capacity and deformability. The BMHDC jacket can be used to strengthen the large eccentric columns. Theoretical prediction is proposed for strengthened masonry columns.
Abstract This work presents the results of an experimental study on the compressive performance of clay brick masonry columns strengthened with bar mesh highly ductile fiber reinforced concrete (BMHDC) jacket. The test parameters consist of strengthening method and loading eccentricity. The analysis in terms of failure mode, peak load, axial load-displacement curves and ductility proves that BMHDC jacket is an effective reinforcing technique which can significantly improve the load carrying capacity and deformability of masonry columns. Although the maximum load of masonry column is decreased with the increase of loading eccentricity, the effectiveness of using BMHDC jacket is not weakened by the initial eccentricity. Moreover, for the convenience of strengthening design in the practical applications, a theoretical prediction of load carrying capacity for strengthened masonry columns tested under concentric and eccentric loads is proposed on the basis of the plane cross-section assumption and modified biaxial strength criterion of bricks. Predicted results are accurate and consistent with experimental results.
