2. Definition of Building Failure Building failure refers to the loss of load-carrying capacity, safety, or serviceability of a structure or any of its components.

3. Causes of Building Failure 1. Design flaws 2. Poor construction practices 3. Foundation issues 4. Use of substandard materials 5. Environmental factors like earthquakes, floods, etc.

4. 1 Structural Failures • Collapse of beams, columns, slabs, or entire structure • Due to design errors, overloading, or material degradation • Often results in life-threatening situations

5. Non-Structural Failures • Includes cracks in walls, tiles, plastering defects, water seepage • Do not affect the load-bearing capacity • Affects usability, aesthetics, and durability

6. Functional Failures • Poor thermal insulation, sound insulation, lighting, drainage, etc. • Affects user comfort and building performance • Results from inadequate planning or execution

7. Material Failures • Corrosion of reinforcement, concrete cracking, timber decay • Occur due to environmental exposure, chemical attack, aging • Lead to structural and non-structural issues

8. Types of Structural Failures 1. Flexural Failure 2. Shear Failure 3. Buckling 4. Fatigue Failure 5. Foundation Settlement

9. Case Studies of Building Failures 1. Ronan Point (UK, 1968) – Gas explosion collapse 2. Highland Towers (Malaysia, 1993) – Landslide 3. Building collapses in India due to poor construction

10. Prevention of Building Failures • Adherence to design codes and IS standards • Quality control during construction • Periodic inspection and maintenance • Use of durable and certified materials

11. Conclusion Understanding building failures helps in planning, designing, constructing, and maintaining safe and durable structures.
