This paper presents experimental and theoretical investigations on the short-term behavior of stone masonry walls constructed with lime mortar. The walls were strengthened using unidirectional GFRP (Glass fiber reinforced polymers) sheets to resist out-of-plane loads. Two methods of anchorage were used to enhance the behavior of strengthened stone masonry walls by preventing premature peeling-off of the GFRP sheets caused by GFRP debonding. Nine GFRP strengthened limestone masonry wall specimens including two control specimens were tested under combined constant low axial load levels and out-of-plane bending caused by two point monotonic loading. All the specimens have height-to-thickness (h/t) ratio of 7.1. The main variables investigated were GFRP reinforcement ratio, arrangement of GFRP, axial load level, and anchorage method. The strengthened walls showed an improvement in the out-of-plane performance which was significantly enhanced by anchorage. The increase in wall ultimate load carrying capacity reached 100%.

本文介绍了用石灰砂浆建造的砌石墙短期行为的实验和理论研究。使用单向GFRP（玻璃纤维增​​强聚合物）板加固墙体，以抵抗平面外载荷。两种锚固方法通过防止GFRP脱胶而导致GFRP板过早剥离，从而增强了砌石墙的性能。在两个恒定的低轴向载荷水平和由两点单调载荷引起的面外弯曲的组合下，对9个GFRP增强的石灰石砌体墙样品（包括两个对照样品）进行了测试。所有样品的厚度均高（h / t）7.1。研究的主要变量是GFRP增强比，GFRP的布置，轴向载荷水平和锚固方法。加固后的墙显示出平面外性能的改善，而锚固效果则明显增强。墙的极限承载能力提高了100％。
