Considering the inter-story drift ratio limitation of different performance levels under different earthquake hazard levels, the ratio of torsion angle to height of floor is calculated. Then a series of torsion angle demand curves are established and a new method named as torsion angle capacity spectrum method is put forward for the performance based seismic evaluation of irregular plan frame structures. Examples are presented to explain the method principle and to demonstrate the applicability and utility of the proposed methodology. It is concluded that the new method can identify the torsional displacement not only between stories but also among structure members in a story. The new method promotes a lot the performance based seismic design theory.
