As indicated on the drawings.

b. Negative phase effects shall not be considered.

c. Rebound resistance shall be 50 percent.

A positive peak pressure is applied to the steel roof joist framing members in the downward direction. A negative peak pressure is applied to the steel roof joist framing members in the upward or uplift direction.

SECTION 05 21 00 Page 4

1.5.1.2 Analysis

Blast design of steel roof joist framing shall be performed using inelastic dynamic structural analysis methods.

1.5.1.3 Single Degree of Freedom Structural Response Limits

Response limits based on a Low Level of Protection (LLOP).

1.5.1.3.1 Flexural Response - Downward

Rotation of the steel roof joist framing members over the full length shall not exceed 3 degrees at the design blast loading.

Flexural response limits for downward loading are based on the assumption that deformation occurs by tensile yielding in the bottom chord. Top chords may need additional bracing to prevent buckling.

1.5.1.3.2 Flexural Response - Upward

Ductility ratio of the steel roof joist framing members shall not exceed

1.5 at the design blast loading.

Additional anchors may be needed to prevent pull-out failures. Bottom chords may need additional bracing to prevent lateral buckling.

1.5.1.3.3 Shear Response

Ductility ratio of the steel roof joist framing members shall not exceed

0.8 at the design blast loading.

Shear response limits apply if member capacity is limited by the capacity of the web members, or web connections, or support connections. Shear response ductility ratio is equal to the peak shear force divided by the shear capacity.

1.5.1.4 Static and Dynamic Increase Factors

A dynamic increase factor (DIF) of 1.19 may be applied to the yield stress for steel members to account for strain rate effects. In addition to the

DIF, a static increase factor (SIF) of 1.05 may also be applied to yield stress for steel members.

1.5.2 Blast Report

Submit blast report, including a summary narrative, structural design sketches, and Blast Design Calculations for all steel roof joist framing showing compliance with blast performance requirements for review and approval.

The blast report shall be prepared and submitted by a qualified blast engineering consultant as defined in the paragraph entitled "Blast Consultant Qualifications" of this specification. The blast report shall be signed and sealed by a registered professional engineer.

1.5.3 Blast Analyses Standards

SECTION 05 21 00 Page 5 meet requirements of Department of Defense (DoD) facilities and shall be designed using established methods and approaches for determining dynamic loads and dynamic structural response.

1.6 DELIVERY, STORAGE, AND HANDLING
