CONNECTING DEVICE OF A DISPLACEMENT METER MEASURING RELATIVE DISPLACEMENT FOR A SHAKING TABLE TEST AND A CONNECTING METHOD THEREOF, SUITABLE FOR CONNECTING THE LVDT FOR MEASURING RELATIVE DISPLACEMENT CORRESPONDING TO THE CRACKS ON A MEASUREMENT OBJECT GENERATED BY A LOAD IN THE SHAKING TABLE TEST

摘要

PURPOSE: A connecting device of a displacement meter measuring relative displacement for a shaking table test and a connecting method thereof are provided to easily measure the crack width and the vertical displacement of a concrete structure which is bent by a load when performing the shaking table test.;CONSTITUTION: A connecting device(100) of a displacement meter measuring relative displacement for a shaking table test comprises an LVDT(Linear Variable Differential Transformer), a displacement meter block(110), a displacement moving block(130), springs(140), spring jigs(120), a base plate(150), and a metal wire. A core unit(170) of the LVDT is inserted into the displacement block, thereby being fixed. The displacement meter moving block is arranged under the displacement meter block. The spring elastically connects the displacement meter and the displacement meter moving block. The spring jigs are attached respectively to the end portions of both lateral sides of the displacement meter moving block and the displacement meter block, thereby being joined to the springs. The metal wire fixes the displacement meter moving block to the base plate.;COPYRIGHT KIPO 2013
