- A cyclic pushover test of a three-story steel plate shear wall (SPSW) specimen was conducted to investigate the seismic behavior of this system when plastic hinge was predicted to develop along the span of horizontal boundary elements (HBEs). The experiment demonstrated that the in-span plastification caused a significant accumulation of plastic incremental deformations of HBEs. It also allowed to experimentally verify that moment–rotation hysteresis curves of HBE connections in SPSWs are not symmetric, but rather lopsided toward one direction, unlike that of special moment-resisting frames. Several of special moment connections experienced fractures, which is attributed to a higher rotation range prior to fracture of those connections. A finite element investigation of the tested specimen showed similar overall behavior to that observed during the experiment.
