Bending and rotational behaviour of semi-continuous composite beams

WANG Jingfeng, LI Guoqiang

Frontiers of Structural and Civil Engineering 2008, Volume 2, Issue 2,   Pages 116-122 doi: 10.1007/s11709-008-0015-9

Abstract: Stresses and deflections were measured in various semi-continuous composite beams. The bending and rotational capacities of the composite connections were measured in terms of beam curvatures and deflections by using two full-scale semi-rigid composite frames with monotonic loadings. The effect of semi-rigid connections on the performance of composite beams with various loadings was compared with predictions and codes. The tests show that the semi-continuous composite beams are more economic and effective than the simple or continuous composite beams. The semi-rigid connections affect the bending capacities and beam deflections, so the connection behavior should be considered in the design of composite beams. Yielding analysis of the steel beam bottom flange has some influence on the deflection calculation of composite beams.
