近地表贴装钢丝绳(SWR)为提高粘土砖非配筋砌体结构的抗震性能提供了一种经济有效的改造方案。本文通过拉拔试验研究了粘土砖基层与SWR之间的粘结强度。研究了各种参数，包括SWR直径、沟槽尺寸、SWR粘结长度、粘结剂类型(即环氧胶、水泥基和石灰基)，以及粘土砖基层的抗压强度。NSM-SWR被粘贴在古董实心粘土砖的组合上，并进行了单调和半循环拔出试验，结果如下所示。提出了基于试验结果的抗拔强度预测模型。
Near surface mounted (NSM) steel wire rope (SWR) provides a cost-effective retrofit solution to improve the seismic performance of clay-brick unreinforced masonry structures. Investigation of the bond strength between the SWR and the clay-brick substrate by means of pull-out tests is presented herein. Various parameters were investigated, including SWR diameter, groove dimensions, SWR bonded length, adhesive types (i.e. epoxy, cement-based grout, and lime-based grout), and compressive strength of the clay-brick masonry substrate. The NSM-SWR was adhered to assemblages of vintage solid clay-bricks and subjected to monotonic and semi-cyclic pull-out testing, with the results being presented herein. A pull-out strength prediction model is proposed based on experimental findings.
