What advantage do brace frame structures offer over moment frame structures in terms of lateral load resistance?

37. What advantage do brace frame structures offer over moment frame structures in terms of lateral load resistance?

1. Greater flexibility
2. Enhanced stiffness
3. Reduced material cost
4. Improved ductility

Answer

The correct answer is: D) Improved ductility

Explanation

When compared to moment frame buildings, braced frame structures usually have more ductility. This means that they can take lateral loads, such as seismic forces, better since the energy is dispersed during the brace-yielding process rather than failing suddenly and brittlely.
