【摘要】 进行了6块混凝土双向板的加固试验研究,采用了集中荷载的加载方式,主要对混凝土双向板的玄武岩纤维布加固进行了试验,分析了构件的破坏形态及承载力的影响因素,探讨了玄武岩纤维布加固双向板的效果,并提出了理论计算公式,为工程实践提供了理论依据与技术支持。更多还原

【Abstract】 Through the tests on 6 bidirectional boards of reinforced concrete,and by the centralism load the increase way,we mainly carried on the experiment on the concrete bidirectional board strengthened with CBF sheet,studied the failure modes and the influence factors of bearing capacity,and discussed the effect of it.The formulas of calculating are put forward.Calculation results of these formulas basically agree well with the experimental results,which provides the effective theory and technique surports for practical projects.更多还原
