Question

What is a common characteristic of non-engineered structures?

• A. They are designed for high disaster resistance.
• B. They are built by qualified architects.
• C. They typically use traditional knowledge and local skills, and are generally not disaster-resistant.
• D. They require extensive government funding and oversight.

Answer 1

Answer:

C. They typically use traditional knowledge and local skills, and are generally not disaster-resistant.

Non-engineered structures are built without the formal design and supervision of qualified architects or engineers. Instead, their construction relies on a community's traditional building methods and the skills of local masons or builders. While these methods may be culturally significant and often use locally available materials, they usually don't incorporate the scientific principles of load-bearing, material strength, or hazard resistance that are essential for withstanding disasters like earthquakes, hurricanes, or floods. This lack of a professional, technical design makes them highly vulnerable and a significant risk to lives and property during a disaster.
