Cyclic Tests of Full‐Scale Composite Joint Subassemblages

Abstract
Three full‐scale composite joint subassemblages, representing parts of the six‐story prototype test structure, were built and tested cyclically under a program of controlled displacements. The specimens included two flange joints, one exterior and one interior, and one exterior web joint. The tests were conducted to study the stiffness, strength, ductility, and energy dissipation capacity of the subassemblages, emphasizing the effects of the composite slab and the panel zone deformation. Theoretical predictions of the subassemblage behavior have been developed and compared with the test results.
