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

摘要

PROBLEM TO BE SOLVED: To provide a construction method and a structure for self-base- isolation whereby the natural frequency of an RC type structure can be made longer without use of a base isolator and an earthquake control device.;SOLUTION: An unbounded prestressing steel member 3 is passed through a precast concrete beam 2 along the longitudinal direction of the beam, with each end of the steel member 3 anchored to a precast concrete column 1 to permit uplift of a column-and-beam connecting interface due to the elastic elongation and deformation of the steel member 3 under a horizontal force produced by an earthquake or the like.;COPYRIGHT: (C)2002,JPO
