|発明の名称||DEVICE FOR OBSERVING DYNAMIC BEHAVIOR OF STRUCTURAL MEMBER|
PROBLEM TO BE SOLVED: To provide a device for observing the dynamic behavior of a structural member, capable of setting various boundary conditions which include the buckling of the structural member using one device.
SOLUTION: The device for observing the dynamic behavior of a structural member comprises a long rack, a pair of support members, and a pair of chucks located on bases to connect the terminal part of each support member to rigidly grip both end parts of a long specimen structural member. The first chuck and its base comprise a first mutual link means to enable fixation, release from the fixation, and free rotation of the first chuck and the movements in the axial direction of the specimen structural member prior to testing. The remaining second chuck and its base comprise a second mutual link means for enabling free rotation, forceful rotation, fixation, and release from the fixation of the second chuck.
