LOADING EXPERMENT DEVICE FOR EARTHQUAKE RESISTANT PERFORMANCE TEST OF COLUMN MEMBER CONSIDERING LONG-TERM DEFORMATION

摘要

PURPOSE: A device for testing the seismic performance of a column member with consideration for long-term deformation is provided to accurately perform a test with respect to the deflection and the compression of the column member as the column member is integrated into a measurement base manufactured of reinforced concrete. CONSTITUTION: A device for testing the seismic performance of a column member with consideration for long-term deformation comprises a measurement base (20), a column member (30), a lower jig (40), an upper jig (50), a connection rod, an oil jack (70), a load cell (80), and a tension maintaining nut (90). The measurement base is formed of reinforced concrete. The column member is inserted into the top surface of the measurement base to be integrated at predetermined height. The lower jig is buried into the measurement base, thereby being fixed to be integrated. The upper jig is seated on the top surface of the column member. The connection rod is arranged by being spaced from a vertical central line (Z) of the column member in both sides at a predetermined distance. One end of the connection rod is pivot-connected to the lower jig, and the other end of the connection rod is penetrated through the upper jig.
