Measurements of Dynamic Properties of Concrete Materials Using Bender Elements

벤더 엘리멘트를 이용한 콘크리트의 동적물성치 측정

A series of seismic tests was carried out using piezoelectric elements called "bender elements". A pair of bender elements can be used as a source and a receiver respectively to measure dynamic properties of concrete. The most suitable bender elements were developed and implemented to measure P wave velocity changes due to the cracks of a concrete beam caused by bending.
