A continuous concrete flooring system consists of a 3-in thick concrete slab supported by 15-in wide integral joists spaced 6 ft on center. The floor slab is loaded with a uniform factored load of 3000 Ib/ft? over a simplý supported span of length L = 20 ft. The concrete has a compressive strength of 3000 psi and depth d can be provided in a single row. Show that Mu s OMn. reinforcement is Grade 60 steel. Calculate the minimum number of # 11 bars at a 24 in from the top face required to support the flexural load. Assume the reinforcement %3D

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.
