EXPERIMENTS ON CONTINUOUS COMPOSITE BEAMS

Tests are presented of six continuous composite beams of 9M length and having compact steel section. Two beams had limited rotation capacity and were tested under severe sagging rotation conditions; the other four were loaded symmetrically and included cases where local buckling contributed to failure. It is proposed that beams having a ductility parameter greater than 1.4 can be designed using simple plastic theory, without regard to loading and span configuration. An assessment is made of the vertical shear resistance of the slab at interior supports. It is concluded that simple plastic design incorporating full plastic moment values may be confidently used in continuous composite beams having compact steel section, adequate slab and shear connection, even under conditions of severe rotation requirement.
