METHOD FOR RESTRICTING HORIZONTAL DISPLACEMENT

摘要

PROBLEM TO BE SOLVED: To provide a method for restricting horizontal displacement that follows a relative displacement of a part above a seismic isolator, and enables a horizontal restricting material to be fitted and removed readily.SOLUTION: A method for restricting horizontal displacement restricts horizontal displacement of an existing building 1 when base-isolating the existing building 1. The method for restricting horizontal displacement includes the following steps for: constructing a retaining wall 30 outside of the existing building 1 and forming a clearance space 7 between the retaining wall 30 and the existing building 1; and installing a plurality of steel floor units 40 between the retaining wall 30 and the existing building 1 as a horizontal restricting material capable of following displacement in a vertical direction, the steel floor unit including a steel beam member and a steel floor member.SELECTED DRAWING: Figure 5
