    29、ovements, elements and pedestrian or vehicular routes located on a site. Hardened network: a network intended to provide the level of reliability and resiliency of an emergency communication system during and immediately following a natural or manmade disaster in accordance with a service level agre

    30、ement with the operator of the emergency communication system that specifies requirements including, but not limited to, the following: protection from storm damage, immediate and long-term clean power backup systems, surge protection for electronics, monitoring, security and maintenance schedules.

    31、Site: a parcel of land bounded by a lot line or a designated portion of public right-of-way. General Structures shall be categorized according to Table 2-1 for the purposes of determining wind, ice and earthquake loads based on the risk to human life, damage to a facility in the event of failure, an

    32、d the primary use and intended purpose of the structure. When surrounding facilities have a higher risk category than the structure, categorization of the structure shall use the risk category of surrounding facilities if the facility could be damaged or physically impacted in the event of failure o

    33、f the structure. When surrounding facilities have a higher risk category than the structure but the facility would not be damaged or physically impacted in the event of failure of the structure, the risk category of the structure shall not be based on the risk category of the surrounding facilities.

    34、 2.2.2.1 Multiple Services It shall be permissible to categorize structures used primarily for commercial services as Risk Category II when the structure is also used to support antennas, radios, equipment or other appurtenances for fire, police or other emergency communication services and the site

    38、 for self-supporting structures. 2. Ice and earthquake loading need not be considered for Risk Category I structures. 3. No load factor shall be applied to the initial tension of guys. 4. Load combinations 2 and 5 apply to self-supporting structures only. Notes: 1. Unfactored dead loads shall be use

    39、d to determine seismic load effects in loading combinations 4 and 5. 2. For foundation designs, the weight of soil directly supported by the foundation and the weight of the foundation shall be considered as a dead load in all loading combinations. For guy anchor foundations, the weight of soil dire

    40、ctly above the foundation and the weight of the foundation shall utilize a 0.9 dead load factor. For all foundation types, when determining a soil nominal resistance that is a function of soil weight (e.g. gross soil bearing resistance, skin friction, lateral soil resistance, etc.), a factor of 1.0

    41、shall be applied to the weight of soil and the resulting soil nominal strength shall be multiplied by the appropriate resistance factor defined in 9.4 to determine the soil design strength. (Refer to sections 9.4 and 9.7). 2.4 Temperature Effects The design tension of guys shall be based on an initi

    42、al temperature of 60 degrees Fahrenheit 16 degrees C. In the absence of more accurate site data, a 50 degrees Fahrenheit 28 degrees C reduction in temperature shall be considered to occur with loading combinations that include ice.

Glaze ice: ice accretion assumed to have a unit weight of 56 lb/ft38.8 kN/m3. Height of structure, h: the height of a structure, including latticed or
