Numerical investigation on a seismic testing campaign on adjustable pallet rack speed-lock connections

This paper presents numerical simulations of a suite cantilever seismic tests speed-lock connections between beam and upright members adjustable pallet rack systems. The tested specimens differ in the endplate-to-beam weld beads geometric configuration; experimental results show that each configuration leads to different behavior, significantly affecting connection capacity ductility. As result, performed aim better understand deepen these observations. Special attention is paid initial (elastic) behavior assembly, albeit stress redistribution after first yielding has also been studied found be relevant. are satisfactory compared with ones, specific remarks derived. work part broader research effort aimed improve dissipative racks; such activity involves upright-base plate testing, advanced simulation, proposal ductility factors.
