Steel-shear-link utilizing corrugated panel for ductile deformation and energy dissipation

In the paper, a new form of energy-dissipation steel shear link with corrugated panel (CSSL) was proposed. Firstly, its basic design principle was suggested, with reference to previous research of traditional steel shear links and steel girders with corrugated webs. On the basis, 10 specimens of CSSL with different configuration parameters were designed and experimentally investigated. The hysteretic characteristics, failure modes and bearing-deformation capacity were analyzed and discussed. The test results confirmed that CSSL specimens had satisfactory hysteretic behavior, with the shear buckling displacement angle over 6 %. Reducing the web height- thickness ratio could significantly improve the bearing and plastic shear deformation capacity of CSSL, decreasing the web panel aspect ratio could also effectively improve the plastic overstrength and shear buckling deformation capacity, and increasing the ripple angle of the corrugated web panel could help improve the shear buckling displacement angle to some extent.
