COMPLETE COLLAPSE PREVENTIVE MEMBER OF EXISTING WOODEN FRAMEWORK STRUCTURE IN EARTHQUAKE TIME

摘要

PROBLEM TO BE SOLVED: To provide a complete collapse preventive member for suddenly exhibiting resistance force from the vicinity of exceeding 1/15 radian in an interlayer deformation angle, though the resistance force is not substantially exhibited for shear force in the initial stage of deformation of a wooden framework structure of receiving external force by an earthquake, and a method for preventing the existing wooden framework structure from completely collapsing in earthquake time by utilizing the complete collapse preventive member.;SOLUTION: In a complete collapse preventive member 200 constituted by arranging a woody rectangular frame 210 and at least two woody triangular frames 220 arranged in a plane formed of the woody rectangular frame 210 in a mutually relatively unmovable mode, the complete collapse preventive member 200 is arranged in a plane space constituted of a column and a horizontal member of an existing wooden framework structure so that an outside side surface of an individual member of the woody rectangular frame 210 and an inside side surface of the column and the horizontal member are substantially brought into close contact with each other.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
