英文摘要: Abstract(#br)Traditional definition of the effective width of steel-concrete composite beam is based on a certain beam section. Section-based effective width changes from one section to another along the beam span. Therefore, effective width for deflection calculation of composite beam should be evaluated based on an element, rather than a specific section. This paper firstly presents the development of two theoretical models for composite beams. One is shear-lag slip beam model (SSM), which takes into consideration both slip effects and shear-lag effects. The other is slip beam model (SLM), which only considers the interface slip between steel beam and concrete slab. Validation of the theoretical models is performed through comparison of the theoretical predictions with the results...
