(Ord. No. 90-11, § 7, 3-6-90)
Sec. 8-1-137. - Design standards.¶
(a) General standards.
(1) Signs and sign structures shall be designed and constructed to resist wind and seismic forces as specified in this section. All bracing systems shall be designed and constructed to transfer lateral forces to the foundations. For signs on buildings, the dead and lateral loads shall be transmitted through the structural frame of the building to the ground in such manner as not to overstress any of the elements thereof.
(2) The overturning moment produced from lateral forces shall in no case exceed two-thirds of the dead load resisting moment. Uplift due to overturning shall be adequately resisted by proper anchorage to the ground or to the structural frame of the building. The weight of earth superimposed over footings may be used in determining the dead load resisting moment. Such earth shall be carefully placed and thoroughly compacted.
(b) Resistance to wind pressure. Signs and sign structures shall be designed to withstand the minimum horizontal pressures set forth in table no. 1, allowing for wind from any direction. The wind pressures set forth in table no. 1 are minimum values and may be adjusted by the director for areas subjected to higher wind pressures.
(c) Calculation of wind pressure. Signs and sign structures shall be designed and constructed to withstand pressures acting upward normal to the surface, equal to 1¼ times those specified for the corresponding height zone in which the roof is located. The height is to be taken as the mean height of the sign above grade and the pressure assumed on the entire sign area.
TABLE NO. 1. WIND PRESSURES FOR VARIOUS HEIGHT ZONES ABOVE GRADE
| Height Zone (feet) | Wind Pressure Map Area (pounds per square foot) |
|---|---|
| Less than 30 | 20 |
| 30 to 49 | 20 |
| 50 to 99 | 25 |
| 100 to 499 | 30 |
| 500 to 1,199 | 35 |
| 1,200 and over | 40 |
(d) Seismic loads. Signs and sign structures shall be designed and constructed to resist seismic forces as specified in the Uniform Building Code.
(e) Combined loads. Wind and seismic loads need not be combined in the design of signs or sign structures; only that loading producing the larger stresses need be used. Vertical design loads, except roof live loads, shall be assumed to be acting simultaneously with the wind or seismic loads.
(f) Allowable stresses. The design of wood, concrete or steel members shall conform to the requirements of the Uniform Building Code. Loads, both vertical and horizontal, exerted on the soil shall not produce stresses exceeding those specified in the Uniform Building Code. The working stresses of wire rope and its fastenings shall not exceed 25 percent of the ultimate strength of the rope or fasteners. Working stresses for wind or seismic loads combined with dead loads may be increased as specified in the Uniform Building Code.
(Ord. No. 90-11, § 7, 3-6-90)
Sec. 8-1-138. - Construction specifications.¶
(a) Generally. The supports for all signs or sign structures shall be securely built, constructed and erected in conformance with the requirements of this article.
(b) Materials. Materials of construction for signs and sign structures shall be of the quality and grade as specified for buildings in the Uniform Building Code. In all signs and sign structures, the materials and details of construction shall, in the absence of specified requirements, conform with the following:
(1) Structural steel shall be of such quality as to conform with Uniform Building Code Standard No. 27-1-58. Secondary members in contact with or directly supporting the display surface may be formed of light gauge steel provided such members are designed in accordance with the specifications of the design of light gauge steel as specified in Uniform Building Code Standard Nos. 27-2-58 and 27-3-58, and in addition shall be galvanized. Secondary members, when formed integrally with the display surface, shall be not less than no. 24 gauge in thickness. When not formed integrally with the display surface, the minimum thickness of the secondary members shall be no. 12 gauge. The minimum thickness of hot-rolled steel members furnishing structural support for signs shall be one-fourth inch, or 3/16 inch if galvanized. Steel pipes shall be of such quality as to conform with Uniform Building Code Standard No. 27-4-58. Steel members may be connected with one galvanized bolt provided the connection is adequate to transfer the stresses in the members.
(2) Anchors and supports, when of wood and embedded in the soil or within six inches of the soil, shall be pressure-treated with an approved preservative. Such members shall be marked or branded by an approved agency.
(c) Use of combustible materials. Ground signs may be constructed of any material meeting the requirements of this article. Combination signs, roof signs and projecting signs shall be constructed of incombustible materials, except as provided in subsection (d) of this section. No combustible materials other than approved plastics shall be used in the construction of electric signs.
(d) Nonstructural trim. Nonstructural trim may be of wood, metal, approved plastics or any combination thereof.
(e) Anchorage.
(1) Members supporting unbraced signs shall be so proportioned that the bearing loads imposed on the soil in either direction, horizontal or vertical, shall not exceed the safe values. Braced ground signs shall be anchored to resist the specified wind or seismic load acting in any direction. Anchors and supports shall be designed for safe bearing loads on the soil and for an effective resistance to pull-out amounting to a force 25 percent greater than the required resistance to overturning. Anchors and supports shall penetrate to a depth below ground greater than that of the frost line.
(2) Portable ground signs supported by frames or posts rigidly attached to the base shall be so proportioned that the weight and size of the base will be adequate to resist the wind pressure specified in table no. 1.
(3) Signs attached to masonry, concrete or steel shall be safely and securely fastened thereto by means of metal anchors, bolts or approved expansion screws of sufficient size and anchorage to support safely the loads applied.
(4) No wooden blocks or plugs or anchors with wood used in connection with screws or nails shall be considered proper anchorage, except in the case of signs attached to wood framing.
(5) No anchor or support of any sign shall be connected to or supported by a parapet wall unless such wall is designed in accordance with the requirements specified in section 2312, appendix, of the Uniform Building Code for parapet walls.
(f) Display surfaces. Display surfaces in all types of signs may be made of metal, glass or approved plastics, in accordance with the area limitations set forth in tables no. 2 and no. 3.
TABLE NO. 2. LIMITATIONS ON APPROVED PLASTICS IN SIGNS
| Area of Facing or Display Surface (square feet) | Area Occupied or Covered by Plastics |
