Experimental investigation of short links in shear

This paper presents an expetimental investigation of short links in shear. Four types of short links were chosen, each having the same cross section HEA100 and the same length, but with different number of stiffeners, i.e. with three couples of stiffeners, two, one and without any stiffener on the seismic link length. The main purpose of stiffeners is to preserve buckling of the seismic link web, i.e. to achieve plastification of cross section by shear. The laboratory experiments were conducted with the auxiliary structure simulating boundary conditions for links in the real eccentrically braced steel frame. The links were examined in pairs. Loading is applied statically using an actuator type Zwik/Roell. Vertical and horizontal displacements are measured for each specimen using the LVDT devices and the web strain of the seismic link is measured by the use of tensometrical gauges. On the base of experimental testing of the seismic links with different number of stiffeners Shear force-Displacement Relationships was obtained. Behaviour of different types of short links in elastic region is identical. When adding stiffeners, shear force at which the seismic link yields, increases. A greater amount of seismic energy may be dissipating in short links with two and three couples of stiffeners.
