SEISMIC REINFORCING EXTERNAL FRAME CONSTRUCTION METHOD OF EXISTING BUILDING

摘要

PROBLEM TO BE SOLVED: To provide a seismic reinforcing external frame construction method capable of harmonizing with the strength of the SRC structure or the SRC structural + RC structural existing building and a seismic reinforcing external frame and preventing an unreasonable stress from working on the existing building by a horizontal force to effectively control the vibration. SOLUTION: The upper and lower reinforcing column unit 5 arranged at the outside of SRC structure of the existing building is united by the bolt connection or welding connection of the vertical steel frame body 12, in the precast SRC made reinforcing beam unit 6 arranged between laterally adjusting reinforcing column units 5 and the reinforced column unit 5, respective vertical steel frames 14 are connected by bolts or welding, the gap between a precast RC made reinforcing column unit and a reinforcing beam unit is connected together by the vertical PC member and the lateral PC steel member to construct an external frame. The external frame and the existing building are connected by a connection slub. COPYRIGHT: (C)2005,JPO&NCIPI
