Chapter 17 Structural Tests and Special Inspections
1701.1 [Replacement] Scope The provisions of this chapter shall govern the quality,
workmanship and requirements for materials covered. Materials of construction and
tests shall conform to the applicable standards listed in this code.
1716 [Addition] QUALITY ASSURANCE FOR PROGRESSIVE COLLAPSE
REQUIREMENTS
1716.1 [Addition] Scope A quality assurance shall be provided in accordance with
Section 1716.1.1.
1716.1.1 [Addition] When required. A quality assurance plan for progressive
collapse requirements shall be provided for the following structures designed for
various levels of protection as follows:
1. Structures designed to a Very Low Level of Protection (VLLOP) and Low
Level of Protection (LLOP) where horizontal and vertical structural element(s)
provide horizontal and vertical tie force capacity.
2. Structures designed to a Low Level of Protection (LLOP) where vertical
structural element(s) cannot provide vertical tie force capacity and the
alternate path (AP) method is utilized to bridge over the deficient element(s).
3. Structures designed to Medium Level of Protection (MLOP) or High Level of
Protection (HLOP).
1716.1.2 [Addition] Detailed requirements. When required by Section 1716.1.1,
a quality assurance plan shall provide for the following:
1. Horizontal and vertical tie force connections as required based on material
type.
2. Roof and floor diaphragm systems including internal and peripheral ties; and
ties to edge columns, corner columns and walls.
3. Roof and floor connections resisting uplift load requirements.
4. Vertical progressive collapse resisting systems including vertical ties and
bridging connections.
5. Perimeter ground floor columns and walls with enhanced ductility
requirements to ensure shear capacity is greater than the flexural capacity
(MLOP and HLOP structures)
1716.2 [Addition] Quality assurance plan preparation. The design of each
designated progressive collapse resisting system shall include a quality assurance plan
prepared by the registered design professional. The quality assurance plan shall identify
the following:
