Testing and Numerical Simulation of the Shear Resistance of Blind-Bolted Aluminum Connections

Due to their high bending stiffness, torsional and local stability, rectangular section members of Al alloy space structures are frequently utilized as load-bearing elements. However, the joint construction is more complex because closed cross-section. To join without drilling holes in them, a variety blind bolts that can be placed fastened on one side have been devised. The researched this paper known BOM bolt. shear resistance BOM-bolted connections investigated using testing finite element calculations individual bolt groups. According test numerical simulation results, formulas for compressive strength aluminum plate capacity reduction factor long derived.
