ABSTRACT
In this research, a method for estimating reaction forces using the vibration characteristics of steel plates is examined. In general, it is known that the natural frequencies of steel plates decrease as compressive forces on them increase. Applying compressive forces to the steel plates experimentally, the vibration characteristics of the steel plates are obtained, and the changes in natural frequencies of the steel plates as the load increases are understood. The change in natural frequencies when compressive forces act on steel plates is theoretically and analytically determined, and the reaction forces acting on the steel plates are inversely estimated by comparing the change of natural frequencies determined theoretically and analytically with those determined experimentally.
