本文介绍了玄武岩纤维增强聚合物（BFRP）复合材料增强小型粘土砖砌体圆柱体抗压性能的试验和分析研究结果。采用两种装配方案制造的14个圆柱体，并使用一层或两层BFRP网格进行限制，在单调压缩载荷下进行了测试。传统的应变测量系统与数字图像相关（DIC）技术相结合。BFRP约束砌体圆柱体表现出延性行为，表现为应力-应变曲线的软化分支。实验应变、强度和全应力-应变曲线采用文献中可用的解析模型进行建模。本研究提出的CNR模型的修正版本提供了最好的强度预测。
This paper presents the results of an experimental and analytical study on the compressive behaviour of small clay brick masonry cylinders reinforced with a basalt fibre reinforced polymer (BFRP) composite. Fourteen cylinders, manufactured using two assembling schemes and confined using either one or two layers of BFRP grids, were tested under monotonic compression loading. Traditional strain measuring systems were integrated with digital image correlation (DIC) technique. The BFRP confined masonry cylinders showed a ductile behaviour characterised by a softening branch of the stress–strain curve. The experimental strains, strength, and full stress–strain curves were modelled using analytical models available in the literature. A modified version of the CNR model proposed in this study provided the best strength prediction.
