【摘要】 对拉区混凝土保护层中内嵌有预应力碳纤维增强塑料筋加固的混凝土梁的受力阶段进行了分析,对其受弯破坏形态、受弯承载力极限状态及正截面的承载力进行了分析和讨论,导出了对应不同破坏形态下承载力计算公式,并与试验结果相比,得出了一些有益的结论,可供设计参考。更多还原

【Abstract】 The Mure modes, ultimate flexural limit states and calculation methods are investigated about strengthening concrete beam with pre-stressed near surface mounted carbon fiber reinforced plastic bar. Discussing respectively the method of calculation ultimate flexural about the failure modes, and presented the calculating formula of the failure modes, which are in good agreement with the experimental results and may be a reference for practical engineering designers.更多还原
