Abstract
A double steel plates composite shear wall member composed of “L” elements (D-L-SCW) was proposed in this paper and its seismic behavior was preliminarily studied. With the shear-span ratio as test parameter, two specimens with actual ratio of 0.5 were constructed and tested in horizontal low-cycle reverse loading test. The failure modes, hysteretic behavior, skeleton curve, ductility and energy dissipation of the specimens were studied. Results showed that the suggested composite shear wall has significant seismic performance and can make more full use of the properties of both materials. The shear-span ratio mainly affected the peak load of the specimens, whilst it didn’t affect the overall deformation trend.
