(2) analyze and studies show that, when using the plain plate shear wall separately after its flexing hysteresis loop pinch seriously, and its hysteresis loop is fuller when adopting the setback steel plate shear force wall.Adopt the two combination, the latter's advantage has remedied the former defective, makes the stress performance of compound wall more superior;
(3) adopting plain plate and setback steel plate to carry out the lamination combination, is not simple " 1+1=2 " or " 1+1+1=3 ", but the effect of " 1+1＞2 " or " 1+1+1＞3 ".Under the relatively thinner situation of steel plate, the value-rising of its combination back bearing capacity and rigidity is more obvious especially;
(4) result of study shows, the setback steel plate wall not only bears horizontal shear, and can regard the stiffening rib that the plain plate wall is applied as, and the two-way interaction has improved shearing resistance flexing load and flexion stiffness separately widely;
(5), can effectively adjust the multilayer steel plates compound shear wall at the anti-side rigidity and the bearing capacity in stressed stage of difference, with the destruction situation of effective control structure in different phase by changing ratio, setback steel plate wave amplitude and the wavelength of setback steel plate and plain plate thickness.
