DESIGN DATA
PART 1 - GENERAL
1.1
SUMMARY
A. This section
includes wind design criteria for the following:
1. Wind design and
anchorage of pre-engineered metal structures and canopies.
2. Wind design and
anchorage of exposed mechanical and electrical equipment and items.
3. Wind design of other
structure or items as specified or indicated on the Drawings.
1.1
REFERENCE
SPECIFICATIONS, CODES, AND STANDARDS
A. All Work specified
herein shall conform to or exceed the applicable requirements of the
referenced portions of the following publications to the extent that
the provisions thereof are not in conflict with other provisions of
these Specifications.
B. Comply with the
applicable editions of the following codes, regulations and
standards.
1. California Code of
Regulations: Title 24, Part 2, Volume 2, 2007, California
Building Code (CBC).
2. California Building
Code (CBC) 2010 Edition with references to ASCE 7 – 05, as
indicated in the CBC.
1.2
SYSTEM
DESCRIPTION
A. Wind
Design Requirements:
Wind design shall be in accordance with the requirements
of the CBC, except when OCSD wind design standards are more stringent
than CBC.
1. CBC
Occupancy Category:
III
2. CBC
Wind Exposure Category:
Exposure C
3. CBC
Basic Wind Speed:
85 miles per hour.
4. Wind Importance
Factor (Iw):
a. All systems: Iw =
1.15
5. Use anchor bolts,
bolts, or welded studs for anchors for resisting wind forces. Anchor
bolts used to resist wind forces shall have a standard hex bolt head.
Do not use anchor bolts fabricated from rod stock with an L or J
shape.
a. Do not use
concrete anchors, flush shells, chemical anchors, powder
actuated fasteners, or other types of anchor unless indicated on the
Drawings or accepted in writing by the ENGINEER.
b. Wind forces must be
resisted by direct bearing shear and tension on the anchors used to
resist wind forces. Do not use connections which use friction to
resist wind forces.
1.3
SUBMITTALS
A. Shop
Drawings and Documentation:
Submit complete shop drawings and documentation for equipment,
fabrications and construction subjected to wind loads, including
anchorage criteria.
B. Calculations:
Calculations for equipment, fabrications, construction, and
anchorages subject to wind loads shall be prepared, signed, and
sealed by a civil or structural Professional Engineer licensed to
practice in the State of California. These wind calculations shall
not be submitted unless specifically requested by the ENGINEER or the
Building Code Official.
C. Foundation
and Support Load Summaries:
All foundation and support load summaries for equipment,
fabrications, and construction subjected to wind loading and
supported on structures designed by others shall include the wind
load reactions applicable to foundations and supporting structures.
D. Design
Certification:
Two (2) copies or written certification, prepared and signed by a
Registered Professional Engineer licensed to practice in the State of
California, shall be submitted by the building, equipment, or
item supplier attesting that their tankage, mechanical and
electrical equipment, pre-engineered metal structures and canopies,
and their anchorage systems have been designed to meet the specified
wind requirements of the CBC and these Contract Documents.
