Abstract |
This study investigated the structural performance of wire-integrated steel decks with varied lattice end support conditions through finiteelement analysis. The results indicated that the steel decks with the lattice foots positioned above the supporting structural member have the highersystem stiffness compared to the cases with the lattice foots shifted away from the support. It is also observed that the contribution of the end verticalbars on both the system stiffness and the strength is negligible when the lattice foots are located on the support. It is, especially, revealed that the endvertical bars can be eliminated when the lattice foot length is not smaller than 40mm. The ultimate load-carrying capacity of the system is not significantlyaffected by the lattice end support condition. The failure mode of the system is the top bar buckling at the center of the deck plate, the lattice endbuckling, and the combination of both depending of design intention.
