key term - Earthquake-resistant structures

Definition

Earthquake-resistant structures are buildings and constructions designed to withstand seismic activities, minimizing damage and protecting lives during earthquakes. These structures utilize advanced engineering techniques, materials, and design principles that help absorb and dissipate energy generated by ground shaking. By incorporating flexibility and stability, these designs aim to reduce the risk of collapse or severe damage, making them crucial in earthquake-prone regions.

5 Must Know Facts For Your Next Test

1. Earthquake-resistant structures often feature reinforced concrete or steel frames that provide greater strength and flexibility during seismic events.
2. Building codes in many earthquake-prone areas require specific design standards for earthquake-resistant construction to ensure public safety.
3. Innovative technologies like shape memory alloys and active control systems are being developed to enhance the resilience of earthquake-resistant structures.
4. Retrofitting older buildings with modern earthquake-resistant features is a common practice to improve their safety against potential earthquakes.
5. Community planning that includes earthquake-resistant infrastructure helps mitigate the overall impact of seismic events on urban populations.

Review Questions

• How do engineering principles in earthquake-resistant structures enhance their ability to withstand seismic forces?
  • Engineering principles in earthquake-resistant structures focus on flexibility and strength, allowing buildings to absorb and dissipate seismic energy effectively.
