摘要
对局部加固混凝土梁进行了研究,给出了加固距离的确定方法。通过塑性铰理论,推导了加固后梁的承载力公式,并进行了试验的验证。试验结果表明,局部加固法具有较好的加固效果,和理论值比较吻合。另外局部加固法还为加固连续梁提供一种新的思路。
in this paper, a study on concrete beams locally strengthened with external tendons is reported herein. It is shown how to fix on the critical distance. The Formula of ultimate flexural capacity is given According to Plastic Principle. An experiment is carried out. The results indicate that locally strengthened technique has good property and the calculated flexural capacity has good agreement with the test. The locally strengthened technique shows a new method to reinforce continuous concrete beam strengthened.
