The application of steel fiber reinforced polymer (SRP) as a means of increasing the capacity of masonry columns is investigated in this study. The behavior of 23 solid-brick specimens that are externally wrapped by SRP sheets in low volumetric ratios is presented. The specimens are subjected to axial monotonic load until failure occurs. Two widely used types of masonry columns of differing square cross-sections were tested in compression (square and octagonal cross-sections). It is concluded that SRP-confined masonry behaves very much like fiber reinforced polymers (FRP)-confined masonry. Confinement increases both the load-carrying capacity and the deformability of masonry almost linearly with average confining stress. A comparative analysis between experimental and theoretical values computed in compliance with the Italian Council of Research (CNR) was also developed.
本研究探讨了应用钢纤维增强聚合物（SRP）来提高砌体柱承载能力的方法。文中介绍了23个采用低体积比SRP片材进行外部包裹的实心砖试件的性能。这些试件承受轴向单调荷载直至破坏。对两种广泛使用的不同方形截面砌体柱进行了抗压试验（方形和八角形截面）。研究得出结论，SRP约束砌体的性能与纤维增强聚合物（FRP）约束砌体非常相似。约束作用几乎与平均约束应力呈线性关系地提高了砌体的承载能力和变形能力。还开展了与按照意大利研究委员会（CNR）计算的实验值和理论值之间的对比分析。
