Seismic‐Resistant Special Truss‐Moment Frames

Abstract

This paper presents a new design concept and procedure for seismic resistant special truss‐moment frames, which have been validated by full‐scale tests on full‐span truss‐column subassemblages. The new design concept results in increased economy and excellent inelastic response with stable hysteretic behavior of the special trusses in moment frames when subjected to severe earthquake motions. The new concept also has an added advantage that the structure can be retrofitted after a major earthquake by simply replacing the damaged web members in the special segments of floor trusses. The proposed system is an excellent and efficient seismic resistant framing system for building structures.
