c. Stud walls supporting equipment shall be provided with multiple studs and
d. If precise dimensions and weights of equipment are unknown, anchorage details
shall be based on the best knowledge available, and may be modified during
construction if original assumptions prove to be invalid.
e. Support and restraint of pipes, ducts and conduit of moderate size may be in
accord with the SMACNA "Guidelines for Seismic Restraints of Mechanical
Systems and Plumbing piping systems" or with another approved set of seismic
f. Where external vibration isolators are used on equipment, the isolators must be
anchored to resist seismic lateral forces.
g. Where equipment is placed on computer access floors, the equipment must be
anchored through the access floor to the structural floor below, unless the access
floor system is specifically designed to resist the horizontal and vertical equipment
h. If it is known that equipment shop drawings will provide seismic anchorage
details and that the construction price will include the cost of such anchorage, the
anchorage need not be detailed on the project drawings, if a statement is made on
the drawings that anchorage will be per approved shop drawings.
126.96.36.199 Precast Concrete Wall Panels
Precast concrete wall panels used as lateral load resisting elements shall be designed as
independent elements with no forces transfer across joints.
188.8.131.52 Metric Reinforcing Steel
For projects that use metric dimensions (S.I. units) reinforcing steel must be sized as soft
metric conversions of inch-unit bars, i.e. #10, #13, #16, #19, #22, #25, #29, #36, #43, or
184.108.40.206 Design Wind Pressure
a. The minimum wind velocity to be used in design shall be 80 mph (130 km/hr) per
b. Within mile (400 meter) of the shoreline, all wind designs shall be based on
exposure "D" forces per U. B. C. section 1614 and Table 16-f. Wind Design for
inland locations may be based upon exposure"C", if such an assumption is justified.
