A concrete floor slab 100mm thick is cast monolithic with concrete beams 2.0m on centers. The beams have a span of 4.2m, web width of 250 mm and overall depth of 450 mm. The tensile reinforcement consists of 4-25 mm diameter bars in two rows with 25mm vertical clear spacing. Use material strengths f’c = 21 MPa and fy = 415 MPa. Calculate the following considering a T-geometry: Effective flange width of an interior beam in mm = Depth of uniform stress block at ultimate stage in mm to the nearest whole number = Tensile steel strain compatible with concrete strain of 0.003 in 3 decimal places =

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.
