为研究钢板及碳纤维板两种材料在钢筋混凝土梁抗弯加固中所起作用,以及两种材料对受损的钢筋混凝土梁的加固(包括挠度和承载力)效果,通过对未加固的和两种加固材料加固的钢筋混凝土梁进行加荷试验的方法,获取了相关的试验数据。通过对比说明了两种加固材料对混凝土梁的抗弯承载力及刚度的提高起到了积极的作用,其对受损的钢筋混凝土梁的加固是有效、实用的。通过对梁的破坏形式的观察,破坏现象呈现为加固材料的粘结、锚固连接的破坏等形式,说明在加固工程中更应注重材料之间的粘结和锚固装置的选择和工艺。
In order to study the effect of steel and carbon fiber plate on the flexural strengthening of reinforced concrete beams and the reinforcement (including deflection and bearing capacity) of the two materials on the damaged reinforced concrete beams, Materials reinforced concrete beam load test method, obtained the relevant test data. The comparison shows that the two kinds of reinforced materials have a positive effect on the flexural capacity and stiffness of the concrete beam, which is effective and practical for the reinforcement of the damaged reinforced concrete beam. Through the observation of the destruction form of the beam, the failure phenomenon appears as the form of the bond of the reinforcement material and the destruction of the anchoring connection, which indicates that more attention should be paid to the bonding between materials and the selection of the anchorage device and the process in the reinforcement project.
