Study Notes
Factors Affecting Beams
- Deformation and failure of columns are influenced by size, shape, and configuration.
- Unprotected columns may collapse structurally due to rapid heating.
Types of Beams
-
Steel Beams
- High strength-to-weight ratio makes steel beams popular in construction.
- In a fire, unprotected steel beams heat quickly, leading to loss of load-bearing capacity.
- High thermal conductivity of steel results in rapid heat transfer, increasing risk of deformation or failure.
- Fire-resistant coatings can protect some steel beams from thermal effects.
-
Concrete Beams
- Non-combustible nature of concrete provides good fire resistance.
- Capable of withstanding high temperatures while maintaining structural integrity.
- Behavior in fire can vary; some concrete beams may deform depending on materials and fire protection measures utilized.
