STUDY ON SEISMIC RESPONSE REDUCTION OF SINGLE-STORY ANTI-SYMMETRIC Z-TYPE NC BRACED FRAME

Shingo Komatsu; Takao Takamatsu; Hiroyuki Tamai; Teruaki Yamanishi

This paper proposes an anti-symmetric Z-type NC braced frame as a new system for a seismic response reduction mechanism based on elastic strain energy accumulation. The energy accumulation is obtained from one-directional incremental torsional deformation of the structure and the system has the advantage that the seismic response decreases without damage. Shaking table tests and numerical analyses on single-story models are carried out to clarify the basic capability of this system. Actualscale numerical models with NC braced or hysteretic dampers are analyzed numerically to clarify the seismic response reduction by torsional deformation, brace stiffness and elastic-plastic behavior of the braces.
