In the steel plate shear wall,pulling force of the steel plate can change the force transmission path in the frame.The horizontal component of forces in the upper and lower plates act on the beam,thus bending moment of the beam is reduced.The stiffness requirements of connections can also be reduced.This makes semi-rigid connections possible.Up to this point,the concept of a new type structure named semi-rigid steel frame-steel plate shear wall is presented.In this paper,a single-span and two-story steel plate shear wall with unstiffened welded-bolted connections is designed and low-cycle reverse loading tests and finite element analysis are carried out.There are four conclusions can be drawn: Firstly,the new structure has high ultimate strength and good energy dissipation.Secondly,pulling strips of the first story are more obvious than those of the second story.Thirdly,the steel plate can bear 65.28%~73.87% of lateral load,and 21.98%~33.35% of overturning moment;Fourthly,the connection is not the weak location of the new structure,and semi-rigid connection is reasonable.
