The steel-plate shear wall with concrete filled steel tube columns is a new type of composite shear wall.In order to assess the seismic performance of new shear walls with different constructional measures

experimental study of three specimens with the same shear span ratio 1.5 were carried out under cyclic loading: one with the steel plate and the steel tubes being connected by welding

one with the steel plate and the steel tubes being connected by bolts

and one with the steel plate and the steel tubes being connected by welding as well as with low opening ratio of holes in the steel plate.Based on the experiment

the damage characteristics

hysteretic behavior

load-carrying capacity

stiffness

ductility and energy dissipation of the specimens were contrastively analyzed.The experimental results showed that the connection type between the steel plate and the steel tubes

either in welding or in bolting

had little effect on the overall performance of the shear walls.Compare to the normal steel-plate shear walls with concrete filled steel tube columns

the load-carrying capacity

ductility

stiffness and energy dissipation of the perforated steel-plate shear walls with concrete filled steel tube columns had not obvious change under low opening ratio of holes.
