Composite Steel-concrete — Quiz

Test your understanding of composite steel-concrete with 5 practice questions.

Practice Questions

Question 1

When designing a composite steel-concrete beam, what is the primary consideration for determining the 'degree of composite action'?

Question 2

In the context of composite slab design with profiled steel decking, what is the primary mechanism by which the concrete and steel decking achieve composite action to resist bending moments?

Question 3

Consider a composite beam where the plastic neutral axis (PNA) falls within the concrete slab. What is the implication of this location for the distribution of forces at the ultimate limit state?

Question 4

Which of the following factors is most critical in determining the 'degree of composite action' in a composite steel-concrete beam?

Question 5

For a composite steel-concrete beam subjected to a negative bending moment (e.g., over an interior support in a continuous beam), what is the primary role of the reinforcement within the concrete slab?
