11. Architectural, Mechanical, and Electrical Components
This chapter sets forth requirements for the seismic
rehabilitation of existing architectural, mechanical, and
electrical components and systems that are permanently
installed in, or are an integral part of, a building system.
Procedures of this chapter are applicable to both the
Simplified and Systematic Rehabilitation Methods.
Requirements are provided for nonstructural
components that are rehabilitated to the Immediate
Occupancy, Life Safety, and Hazards Reduced
Nonstructural Performance Levels. Requirements for
Operational Performance are outside the scope of this
Sections 11.2, 11.3, 11.4, and 11.5 provide requirements
for condition assessment, component evaluation,
Rehabilitation Objectives, and structural-nonstructural
interaction. Section 11.6 defines acceleration and
deformation sensitive components. Section 11.7
specifies procedures for determining design forces and
deformations on nonstructural components.
Section 11.8 identifies rehabilitation methods.
Sections 11.9, 11.10, and 11.11 specify evaluation and
acceptance criteria for architectural components;
mechanical, electrical, and plumbing (MEP) systems;
and other equipment.
New nonstructural components installed in existing
buildings shall conform to the requirements for similar
components in new buildings.
The assessment process necessary to make a final
determination of which nonstructural components are
to be rehabilitated is not part of this standard, but the
subject is discussed briefly in Section 11.3.
The core of this chapter is contained in Table 11-1,
1. A list of nonstructural components subject to the
Hazards Reduced, Life Safety and Immediate
Occupancy requirements of this standard.
2. Rehabilitation requirements related to the zone of
seismicity and Hazards Reduced, Life Safety, and
Immediate Occupancy Performance Levels.
Requirements for Operational Performance are not
included in this standard. R
