Floors

The floor system is typically a key load-resisting element in the structural units making up a commercial structure. This lesson examines the structural contributions of concrete, steel, and wood floor framing systems for commercial buildings.

Learning Objectives

At the conclusion of this lesson, you will be able to:

• Identify the principal types of concrete, steel, and wood floor structures
• Evaluate the load path through a commercial floor system
• Explain why the depth is essential to the design of most commercial structures
• Distinguish between deflection and strength
• Describe how one-way and two-way slab systems carry loads
• Explain the difference between plank-and-beam and joisted wood floor systems
