EMPIRICAL-INVESTIGATION ON BUCKLING AND POSTBUCKLING BEHAVIOR OF CELLLINERS

In nuclear-related facilities, many concete walls and slabs are lined with thin stainless steel plates in order to insure against the risk o f accidental air leakage during a severe earthquake. These liners are forcibly deformed with the deformation of the concrete walls and slabs during an earthquake. The purpose of this paper is to obtain basic em pirical data on the shearing behaviour of thin steel plates attached t o concrete, especially to understand the relationship between the shea r strain of the plate and its lateral displacement, as fundamental res earch on the safety of lining plates. A new apparatus for measuring th e lateral displacement of a lining plate by continuously scanning its surface is tested. The apparatus proves to be quite effective for unde rstanding the buckling wave of the lining plate and the essential beha viour of a thin steel plate attached to a concrete wall subject to a s hear force is clarified.
