A series of cyclic push-out tests on specimens with shear studs and steel deck with concrete fill is initiating in
SDII Full-scale concrete-filled steel deck diaphragm tests underway
Concrete-filled steel deck is employed as a diaphragm in countless structural steel buildings. However, the available experimental data on cyclic
Research on seismic collectors progressing
The NSF-sponsored team focusing on seismic collectors in steel buildings, an effort highly compatible with the overall SDII initiative –
Impact of testing on shear performance of bare steel deck connectors
The performance of steel-to-steel connectors in shear are important for cold-formed steel deck diaphragms, but also for a variety of
Behavior of sidelap and structural connectors for bare steel deck characterized
Recent testing conducted by NBM Technologies provides cyclic characterization of both deck-to-deck sidelap and deck-to-frame structural connectors. The tests cover
SDII modeling brings steel fracture into FEM simulations
Simulation of steel structures has advanced markedly in the finite element age and today models that include buckling and yielding
SDII modeling sheds light on interactions between inelastic walls and diaphragms in determining force demands
Using a simplified nonlinear mass-spring model this work provides an examination of how inelasticity in the vertical and horizontal (diaphragm)
Deep dive on warping of steel deck
A recent SDII conference paper provides additional insight on how bare steel deck diaphragms warp under shear. The paper provides
