APPLICATIONS OF SEISMIC RETROFITTING METHOD BY FRAMED STEEL BRACE SYSTEM CONCENTRICALLY JOINTED WITH ANCHORS

Abstract

The authors have developed the seismic retrofitting method by framed steel brace system partially and concentrically jointed with anchors to reduce the number of anchor. Seismic tests of four specimens with mansard type brace, installation method of column inside - beam outside, pin end hollow section brace and pin end double hollow section brace were conducted. The details of test results and design method for the framed steel brace system with them are reported in this paper.
