1. Concrete provides comprehensive fire protection for buildings due to its non-combustible and insulating properties. It protects lives and property by preventing fire spread, not dripping flaming particles, and allowing for easier repair after a fire. 2. Fire-resistant design of buildings requires using non-combustible materials like concrete and steel, protective measures during construction, and fire suppression systems. Proper sizing and reinforcement of concrete elements helps them withstand standard fire exposure times. 3. Performance-based fire engineering involves analyzing heat transfer and structural behavior at high temperatures using computer models. This allows more optimized designs compared to prescriptive code methods.
