4. Conclusions

1) The SPSWS can be simplified as X-brace Model, so as to simulate its contribution to lateral resistant stiffness of structure.

2) The results from the elastic stiffness formulation (5) of SPSWS is rather higher than the test results, the stiffness tolerances between theoretical formula and actual conditions is caused by the complexity of shear wall boundary constraint in actual project, consequently it needs further analysis.

3) The vertical load has little effect on the elastic stiffness decrease of SPSWS.

4) The edge stiffening measures can improve the overall shearing buckling of steel sheet wall, and the reduction of breadth-to -thickness ratio b/t of column between slits can avoid its torsion buckling. But the reasonable setting of slit parameter shall have comprehensive consideration of purpose for buckling resistance and adjusting stiffness and load-bearing capacity.

Obviously, if we want to spread and apply SPSWS in the residential house of steel structure, there are great deals of problems required further or future research. The study above involves discussions of some problems only in structural computation, and only limited to the elastic stage. As an excellent member for energy dissipation and earthquake-resistance, SPSWS shall be more suitable for regions with high intensity. And then, it urgently needs to solve the problems of how to use reasonable simplified model of elasto-plasticity to carry out structural computation.
