Question

A new construction firm cometed it's first project of a residential building. But a few months later, the building developed cracks, and eventually the entire building crumbled to the ground. What caused the building to fall?

Answer 1

Answer:

For a new constructed building, causes of cracks and building failure are;

• permeability of concrete
• poor construction practices
• poor structural design and specifications

Explanation:

Cracks on buildings start when stress in components exceeds its strength. The externally applied forces that cause cracks on structures are : dead forces, live forces, seismic forces or forces on the foundation settlement. Internally forces that cause cracks include variation on temperatures, moisture content changes and chemical actions. Measuring and monitoring movements of cracks can be done through; using tell-tale, using a crack width gauge and use of precision calipers.
