Abstract

Anti-symmetric Z-type NC braced frame is a new structural system that has seismic response reduction capability based on incremental torsional deformation. This torsional deformation is due to the characteristics of NC brace, especially it is necessary to reveal the effect of frame eccentricity in such a system. Against the background, this paper discusses behavior of Anti-symmetric Z-type with eccentricity. First, static loading tests with several eccentric levels were carried, and then time history analyses using the absolute value and sign of eccentricity, building natural period, brace stiffness ratio, and seismic ground motion as variables were conducted.
