The authors proposed the anti-symmetric Z-type non-compression braced frame having seismic response reduction performance due to incremental torsional deformation. In previous papers, we clarify the anti-symmetric Z-type shows incremental torsional deformation characteristics during static and dynamic loading. However, since these results were from experiment with a non-eccentric specimen, actual situation of structural building is not reflect. In this report, static loading test on one-story one-span specimen with eccentric as well as non-eccentric specimen are carried out to clarify torsional deformation behavior of anti-symmetric Z-type NC braced frame. We discus effect of eccentric through the comparison with these specimens.
