 note = {Experimental study using nondestructive testing method on RC pier model is discussed in this paper. Modal vibration method and pulse echo method are used to detect internal damages as a nondestructive testing. Change of modal characteristics and reflection waves returned from the damage are analyzed to identify the scale of damage. Hysteretic absorption energy due to elastic-plastic deformation is a main parameter to evaluation the changes of frequency and damping. And by echo waves we could identify the location of internal crack of RC pier., application/pdf},
