摘要： PROBLEM TO BE SOLVED: To provide a method for detecting damage of a columnar structure, which is capable of detecting the presence of damage, the degree of damage, and a damage direction of the columnar structure in a short time and at a low cost, without depending on variations in the columnar structure.SOLUTION: A vibration generator set between a bottom end and a tip end of a concrete column 1 generates vibrations for swinging the entire concrete column, in multiple horizontal directions. The vibrations for swinging the entire concrete column are received by a receiving sensor 3 installed between the bottom end and the tip end. A damage detection device 10 replaces time-series waveforms in respective circumferential directions, which are received by the receiving sensor 3, by a frequency distribution, extracts a time domain in which vibrations in an excitation direction are dominant, from the replaced frequency distribution, and calculates differences between dominant frequencies in the time domain in which the vibrations in the excitation direction are dominant, for respective circumferential directions. The damage detection device 10 displays a graph of the calculated differences of the dominant frequencies in respective circumferential directions and analyzes the differences of the dominant frequencies for respective circumferential directions to determine the presence of damage, the degree of damage, and a damage direction.

摘要： PROBLEM TO BE SOLVED: To provide a concrete column striking device capable of reducing fatigue of a person who strikes and obtaining accurate vibration data.SOLUTION: A device main body 1 is held against a concrete column in a state that a tip of a probe 5 contacts a surface of a concrete column 14. When the probe 5 is moved inside a housing, a gear 11 engaged with a rack gear on the probe 5 converts a length that the probe 5 moves inside the housing into a number of rotation. A cam type gear 12, which rotates in tandem with the gear 11 and is engaged with the rack gear on an extendable guide 9, converts the number of the rotation into the length that the extendable guide 9 moves in a direction to compress a spring 7. Because the cam type gear 12 has a cam shape, compression of the spring 7, which is released when the cam type gear 12 rotates to a prescribed position, enables a hammer 6 to strike the surface of the concrete column 14.
