📚 Background Theory

Commercial construction is based on several engineering disciplines that work together to create safe and durable buildings.

🔩 Structural Engineering Theory

Structural engineering ensures that buildings can support loads and resist environmental forces. Engineers analyze the following loads:

• Dead loads (weight of building materials)

• Live loads (occupants, furniture, equipment)

• Wind loads

• Snow loads

• Seismic forces

Structural analysis involves calculating how beams, columns, and foundations distribute loads throughout the structure.

Key structural concepts include:

• Load paths

• Structural stability

• Redundancy

• Safety factors

Modern design often uses computer modeling software to simulate structural behavior.
