| 摘 要： | 介绍采用CFRP条带加固钢筋混凝土开孔平板的试验,根据试验构件裂缝分布形态,提出单向破坏和双向破坏两种屈服线模式,应用屈服线理论对单向破坏模式的加固板承载力进行计算,并与试验值进行比较,结果表明理论值与试验值吻合较好。

| Abstract: | An experiment of using the CFRP(carbon-fiber-reinforced-polymer) strips to strengthen the RC flat plate with opening is described.Two yield line models,i.e.the one-way and the bi-way failure type,are put forward according to the crack distribution of the specimen.The ultimate load of the strengthened plate with one-way failure model is calculated based on the yield line theory.A comparison is made between the results of the experiment and the theoretical calculation.Results from the calculation are well coincident with that from the experiment. |
