Abstract: Considering seismic vertical torsion component case, elastic plastic seismic response analysis of the unidirectional eccentric frame structure was done. Torsional responses of four eccentricity unilateral eccentric frame structures under the multi-dimensional seismic were compared. And then the dynamic characteristics and laws of torsion effect about the structure were got.

Keywords: seismic; unidirectional eccentric, torsion reaction
