A 4 m long simply supported steel reinforced timber beam carrying a uniformly distributed load w = 10 kN/m has the cross-section shown in Fig Q1. The elastic moduli of the steel and wood are 210 GPa and 8.5 GPa, respectively.     Calculate the radius of curvature at the composite beam’s midspan. Determine the maximum normal stresses in the steel and the wood under this loading condition. Plot the normal strain and stress distributions across the composite beam section. Determine the composite beam dimensions which ensure that both steel and wood reach their yield strengths at the same time. Assume that yield strengths for steel and wood are 350 MPa and 40 MPa respectively

Composite Construction

Composite construction is the construction of structures in which two or more materials are used. Regarding structural engineering, composite construction is a construction where two materials are bound together in a technical manner such that both the materials act as a single unit to carry and transfer the load. The motives of composite construction are to increase the structural strength, make structures more aesthetic, and provide a sustainable environment.
