VIBRATION-PROOF CONSTRUCTION METHOD AND VIBRATION-PROOF STRUCTURE USING ELASTOPLASTIC BRACE

摘要

PROBLEM TO BE SOLVED: To effectively absorb seismic energy by a compact and simple device by a transmitting the load of vibration of a structure body to a fixed member by the tension by one elastoplastic brace and the compression of the other elastoplastic brace arranged in line symmetry at the same time.

SOLUTION: The elastoplastic braces 9, 9' are arranged in line symmetry via a connecting member 10 surrounding a steel frame column 5, the transmission of the load transmitted from the boiler body 1 to the steel frame column 5 via the connecting member 10 by the elastoplastic braces 9, 9' arranged in line symmetry is carried out at the same time by the tension of the one elastoplastic brace 9 and the compression of the other elastoplastic brace 9', when supporting the load of the boiler 1 by an earthquake by the steel frame column 5.
