Applications of Concrete Framing Systems

A concrete frame is a structure formed by the interconnection of beams and columns to form a structural network. In simple terms, it is the basic skeletal structure of a building or any construction. The concrete framing structure is built on a concrete foundation that forms the base of the entire structure. The concrete frame system is built to support floors, roofs, walls, beams, rafters, joists, etc.

Question

**Problem 3: Design of a Rectangular Concrete Beam**

A rectangular concrete beam with a width of \( b = 24 \) inches is restricted by architectural considerations to a maximum total depth of \( h = 16 \) inches. The beam must carry a total factored moment \( M_u = 400 \text{ kip.ft} \).

**Design Requirements:**
- Determine the flexural reinforcement necessary for this beam, incorporating compression steel if needed.
- Allow a clearance of 3 inches to the center of the bars from either the compression or tension face of the beam.
- Material strengths are specified as follows:
- Yield strength of the steel, \( f_y = 60,000 \text{ psi} \)
- Compressive strength of the concrete, \( f'_c = 4,000 \text{ psi} \).

**Instructions:**
1. Select appropriate reinforcement to meet the required areas.
2. Provide a sketch of the design showing the arrangement of the reinforcement bars.
3. Verify the bar arrangement criteria before creating the sketch.
4. Use #3 stirrups in your design.

This exercise involves calculating and selecting the right amount and arrangement of reinforcement bars to ensure the structural integrity and functionality of the beam while adhering to given architectural and material constraints.
