摘要
通过4根钢筋混凝土梁超声波检测试验,研究了三等分荷载下混凝土梁不同位置和不同应力对超声波声速的影响规律。在试验数据的基础上,拟合得出了混凝土梁构件的拉应力与声速关系曲线,与试验数据吻合较好,并给出系数表,为混凝土梁构件工作应力的检测和评价提供参考。
Through the ultrasonic testing of four reinforced concrete beams,the effects of different positions and intensities of the concrete beams on the ultrasonic velocity under the trisectional load were studied.Based on the experimental data,the fitting curves of ternsile stress and ultrasonic velocity of the concrete beam members are obtained,which is in good agreement with experimental data,We also get the coefficient table,which provides a reference for the detection and evaluation of working stress of concrete beam members.
