SEISMIC STRENGTHENING STRUCTURE AND SEISMIC STRENGTHENING METHOD FOR CONCRETE SKELETON

摘要

PROBLEM TO BE SOLVED: To obtain high earthquake-resistant strength by applying both shear reinforcement and additional reinforcement to a concrete skeleton, and to efficiently perform the shear reinforcement and the additional reinforcement.;SOLUTION: A seismic strengthening structure for a concrete skeleton 10 includes: a slot-like insertion hole 12 that is formed in a skeleton surface 11 of the concrete skeleton 10; an approximately L-shaped shear reinforcement material 20 that has one rod part 21 driven into the insertion hole 12; an anchoring material 30 that flows out from a tubular capsule 35, disposed in the insertion hole 12, due to rupture caused by driving the one rod part 21 and that is infilled into a cavity between the insertion hole 12 and the one rod part 21; and an additional skeleton 40 that is additionally provided outside the skeleton surface 11 in such a manner that another rod part 22 of the shear reinforcement material 20 protruding from the insertion hole 12 and elongated along the skeleton surface 11 serves as a joint bar.;COPYRIGHT: (C)2012,JPO&INPIT
