Self exemption shaking construction and the self exemption shaking structural null precast concrete

摘要

PROBLEM TO BE SOLVED: To provide a self-base isolation method and a self-base isolation structure for an RC(reinforced concrete) structure capable of controlling the maximum horizontal displacement assumed at an earthquake by introducing a technology for bonding the fixed length portion of an unbonded PC(prestressed concrete) steel product to a precast concrete beam, and increasing the horizontal rigidity after the floating-up of the beam.;SOLUTION: The unbonded PC steel product is made to penetrate the precast concrete beam in the longitudinal direction, and both end sections of the unbonded PC steel product are fixed to a precast concrete column. The fixed length portion of the unbonded PC steel product is bonded to the precast concrete beam to control the horizontal displacement caused by the floating-up of the beam.;COPYRIGHT: (C)2002,JPO
