逐层回弹法检测火灾后混凝土强度

介绍了火灾后混凝土结构的各类检测方法。提出了逐层回弹法检测火灾后混凝土强度的方法。进行了逐层回弹法检测火灾后混凝土强度的试验，对试验数据进行数学回归分析，得出了逐层回弹法测强曲线。研究结果对回弹法应用于火灾后混凝土强度的检测有实际意义。

Layer-by-Layer Rebound Method to Assess the Strength of Fire-Damaged Concrete

Different methods of assessment for fire-damaged concrete structure have been introduced in this paper.A new method(layer-by-layer rebound method) is presented to predict the residual strength of concrete exposed to elevated temperature.Corresponding tests have been carried out on concrete specimens by this method and the regression curves of test data are obtained. The results of this paper have practical significance in improving the use of rebound method in the field of fire damage assessment.
