Strength Non-destructive Testing of Concrete Structural Members in Building Engineering
In this study,non-destructive testing(NDT)was used to detect the change in strength of reinforced concrete(RC)buildings due to seismic loads.The seismic input is simulated by a shaking table and applied to a concrete building sample to simulate the structural strength of the sample before and after the earthquake.Direct and indirect acoustic wave methods and ultrasonic tomography detection techniques are ex-plored.Before and after the test,the nondestructive testing method is applied to the sample,and the nondestructive testing is completed by the parameters of wave velocity and interlayer displacement ratio.Finally,the results of the testing method are analyzed and a non-destructive tes-ting method for concrete building structures is proposed,which provides a new testing idea for the relevant testing.
