Hysteretic performance study and lectotype suggestion for three types of thin steel plate shear walls

Abstract:

To study the hysteretic performance and lectotype suggestion of the thin steel plate shear walls with four-side connections, two-side connections and silts, the hysteretic performance of those thin steel plate shear walls were systematically investigated utilizing the ANSYS software package. Comparisons of the initial stiffness, peak load, ductility and energy dissipation capacity of those steel plate shear walls were carried out base on the numerical results. Results showed that those three types of steel plate shear walls had proper ductility and energy dissipation capacity. The hysteretic curves of the thin steel plate shear walls with four-side connections and two-side connections had pinch phenomenon, while their initial stiffness and peak load were relatively high. They could be used in the multistory steel structure residences in high intensive seismic region or high-rise steel structure residences. The hysteretic curves of the thin steel plate shear walls with silts exhibited plump loops, but its initial stiffness and peak load were low. This kind of shear walls could be applied on the multistory steel structure residences in low intensive seismic region or low-rise steel structure residences.
