Behavior of continuous or semi-continuous steel-concrete composite beams

omposite steel-concrete beams have been widely used in the design and construction of modern steel framed buildings. A
steel-concrete structural beam consists of a steel structure as the major and concrete as the minor part. It can be achieved by a
steel beam overlaid by a concrete slab, in which the connection between steel and concrete is achieved by using mechanical shear
connectors (shear studs). Several methods have been introduced to construct steel-concrete composite beams as shown in figure 1
(Uy, 2007). The idea of composite sections refers to the development of shear connectors in the 1950’s which has made practicable
to connect the concrete slabs to the steel beams (Johnson, 1994). Rae et al., 2011 conduct a study to examine the steel-concrete
composite structural frames. Dubai (2007) finds experimentally that shear connectors can be used partially in composite structural
beams. Indeed, the composite steel-concrete structural beams should be studied under diverse loading conditions. For analyzing
the composite beams under combined bending and shear stress there are not adequate references; even codes and standards do
not cover this issue adequately (Liang et al., 2004). There is no doubt that concrete is strong enough in compression and steel in
tension. However, regarding the composite steel-concrete beams, in the sagging moment locations where the steel is subjected to
compression and concrete subjected to tension, it needs to be investigated conservatively. Mainly, this research investigates the
behavior of continuous or semi-continuous beam at the negative moment locations. The loading condition of combined bending and
shear will be covered. This work tries to investigate the problem numerically (Finite Element Method) using the computer software
ANSYS, and the results will be compared with existing experimental data. FE models will be constructed to investigate the reliability
of the simulation of composite steel-concrete structural beams.
