摘　　要：目的建立FRP与砌体界面的粘贴承载力模型.方法对8个试件进行FRP与砌体界面的粘结强度的试验,试验前需对FRP浸胶处理,采用液压千斤顶等速连续加载,拉拔力由荷载传感器计量,纤维片材的应变采用电阻应变计测量,试验数据由UCAM70A采集.结果结合试验数据,考虑块体、砂浆强度和考虑FRP布约束的因素,建立新的FRP与砌体界面的粘贴承载力计算公式.结论提出的FRP与砌体界面的粘结承载力计算模型,为广大工程计算人员提供计算依据.It is an important task in the domain of FRP strengthened masonry to study on anchorage property for FRP attached to masonry. In this paper, experiments of anchorage strength of FRP attached to masonry are carded out,a 100 kN capacity hydraulic jack activated by a manual pump is used to load the specimen. The tensile strength is measured by using a loading transducer, and strain gauges are mounted directly onto the surface of the FRP composite to measure the strain during application of load. The results indicate that the calculated results of the new model are identical to the experiment data very well. The anchorage strength model for FRP attached to masonry is to provide the calculating basis for vast engineers.
