In typical beam and slab composite bridges, such as seen in multi-girder bridges and ladder deck bridges, the design of the beams needs to consider two basic situations – when the steel beams act alone to support the weight of wet concrete and when the steel beams act compositely with the slab (at later stages of construction and during service). This article discusses the principal design considerations for both situations.Get Free Sample

Due to its shape, I beam has high moment of inertia and stiffness which makes it resistant to bending moments. The web provides resistance against shear forces. These beams are not resistant to torsional loading (twisting) and they shall not used in the cases where torsion is dominant.Get Free Sample

find in a later course that the strength of a beam is directly related to the moment of inertia of its cross-section about a centroidal axis. Most beams used for heavy loads have composite cross-sections, so there you are. You can now find the moment of inertia of a composite area about a specified axis.Get Free Sample
