JOINT DAMPER FOR WOODEN FRAMEWORK STRUCTURAL BODY

摘要

PROBLEM TO BE SOLVED: To dispense with excessive reinforcement for reduction in costs and weight and to sufficiently and stably exhibit damper performance in case of normal deformation by theoretically clarifying relationship between a deformation degree of a joint part and maintenance necessity of energy absorbing performance.;SOLUTION: Between a first lateral side part 2a in one hard plate 2 and a first lateral side part 4a in the other hard plate 4 and between a second lateral side part 4b in the other hard plate 4 and a second lateral side part 2b in one hard plate 2, clearances D1 and D2 are arranged so that an angle (tan δ1), which is made between a line connecting the outermost end angle part 2e of the first lateral side part 2a in the hard plate 2 and the innermost end angle part 4e of the first lateral side part 4a in the hard plate 4 together and a mounting part 1, and an angle (tan δ2), which is made between a line connecting the inner most end angle part 2f of the second lateral side part 2b in the hard plate 2 and the outermost end angle part 4f of the second lateral side part 4b in the hard plate 4 together and a mounting part 3, range from 1/15 to 1/4.;COPYRIGHT: (C)2003,JPO
