【摘要】 在工程事故的调查和处理以及建筑结构的补强和加固工作中 ,常常需要准确了解钢筋混凝土构件的实际工作状态。本文从推导服役钢筋混凝土梁应变和挠度的理论关系出发 ,提出了一种测量钢筋混凝土梁实际应力的新方法更多还原

【Abstract】 How to detect the real working state of reinforced concrete beams has attracted the attention of engineerers for a long time.In this paper,the relationship between the displacement and strain of steel bars has been established.And then,a new method of measureing the real stress of reinforced concrete beam is proposed.更多还原
