Non-destructive Inspection of Top Down construction Joints of Column in SRC Structure using Radar and Thermography Method

적외선법과 레이더법에 의한 콘크리트 역타시공 이음부위의 충진상태 평가시험

The joint treatment of concrete is one of the technical problems in top down construction method. Joints created wit the top down construction result in serous weakness from the aspects of both structural and water-barrier function. Several case studies for the insepction of top down construction joints of column in SRC structure using radar and infrared thermography method. The advantages and limitations of these methods for non-destructive inspection in top own construction joints are investigated.
