SEISMIC REINFORCEMENT METHOD OF INNER SQUARE DOOR-TYPE FRAME FOR INTEGRATING THROUGH SHEAR CONNECTION USING GAP LEVEL PLATE AND SLEEVE ANCHOR CAP

摘要

A seismic reinforcement method of an inner square door-type frame for integrating through shear connection using a level gap plate and a sleeve anchor cap can share load by allowing a new vertical column member of a square door-type frame used for new reinforcement to serve as a base plate in a seismic resistance behavior by vertically constructing the new column member even when the new column member is not in close contact with a conventional vertical column and has difficulty in installation thereof or a great distance (S) and a vertical spacing error (h) occurs therebetween, can suppress the occurrence of local ground pressure cracking around bored anchor holes upon boring for installation of anchors, allows the anchors inserted into the bored holes to serve as a rigid reinforcing body, allows the new column of the square door-type frame to have a box-shaped cross section filled with concrete for the purpose of increasing rigidity and strength, prevents the leakage of concrete poured into anchor insertion holes for anchor installation formed in the outer surface thereof, and allows the anchors to be coupled to the new column at anchor points.;COPYRIGHT KIPO 2020
