scope:

This standard provides minimum requirements for planning, assessment, analysis, material selection, design and detailing, construction, and qualification testing to mitigate disproportionate collapse of new and existing buildings and other structures. This standard includes threat-specific and non-threat-specific methodologies and identifies direct design and indirect design approaches.

This standard does not prescribe requirements for blast design. This topic is addressed in other documents (e.g., ASCE 59, Blast Protection of Buildings).

Organization

This standard is organized as follows:

• Chapter 1 provides general requirements.

• Chapter 2 provides terminology used throughout this standard.

• Chapter 3 defines requirements for performing a risk assessment to mitigate disproportionate collapse.

• Chapter 4 provides design objectives, including general initiating hazard scenarios and performance objectives.

• Chapter 5 presents technical approaches to design new buildings, determine the capacity of existing buildings to resist disproportionate collapse, and develop upgrades to existing buildings to mitigate disproportionate collapse.

• Chapter 6 provides acceptance criteria for component and system performance based on the selected analysis/design approach, construction materials, and structural systems.

• Chapter 7 provides minimum requirements and intents for structural detailing of various materials expected to be used as part of a disproportionate collapse mitigation strategy.

• Chapter 8 provides minimum requirements and discussion to evaluate and enhance the robustness of existing buildings and other structures.

• Chapter 9 provides procedures and standards for the peer review of the design of structures to resist disproportionate collapse and the verification of performance of selected components and structural assemblages.

Applicability

The provisions in this standard are applicable to buildings and other structures that are within the scope of ASCE 7, Minimum Design Loads and Associated Criteria for Buildings and Other Structures.
