Seismic Constraints for MEP Services

Earthquakes are major physical occurrences that can have devastating effects on both existing infrastructure and human life. Unfortunately, MEP components are not always considered when earthquakes are considered, but properly attaching the components to the structure can be just as important as properly attaching beams or columns.

• Buildings and other structures that support the mechanical, electrical, or plumbing (MEP) components are divided into occupancy categories, which are used to determine the level of seismic loads and detailing required.
• Essential facilities such as hospitals, police and fire stations, power plants, or water treatment facilities are examples of higher-level occupancy categories (III or IV), which can require a higher level of analysis, design, and detailing than a lower occupancy category building in the same region of the country.
