Abstract

Abstract

Depending on the experiment results analysis of the reinforced concrete frame eccentrically braced with steel (EBF structure) and drift limit comparison of performance-based design and three-stage seismic design, the deflection and behavior of EBF structure under seismic motion is discussed. From the point of three-stage principle of seismic design and performance-based design, the story-drift limit of EBF structure should be more strict than the pure frame. Because of the action of steel brace, the shear force of column in EBF structure is reduced and lateral stiffness of EBF structure is increased. The rupture of column and larger lateral deformation are avoided. It is also found that maximum deformation, acceleration, velocity and column shear of the EBF structure are obviously decreased comparing with the pure frame. The K-type brace is advantageous for the earthquake resistance.
