KYLE D DUMBLETON Page 2 9/5/2008 • IBC 1603.1.3/Comm 62.1603(1)-The ground snow load Pg shall be indicated. In areas where the ground snow load Pg,exceeds 10 pounds per square foot,the following additional information shall also be provided, regardless of whether snow loads govern the design of the roof: flat-roof snow load Pf;snow exposure factor Ce; snow load importance factor I;thermal factor Ct;any sloped-roof snow load,Ps;and any unbalanced,drift or sliding snow loads. These shall all be indicated on the construction documents. • IBC 1603.1.4-Basic wind speed,wind importance factor I,wind exposure&applicable directions,internal pressure coefficient,and component&cladding design pressure shall be shown in the construction documents. • IBC 1604.4- Structural member&connection rational analysis in accordance with well-established principals of mechanics results in a system that provides a complete load path capable of transferring loads from their point of origin to the load-resisting elements. Structure shall be designed to resist the overturning effects of lateral forces. • IBC 1604.5-Proper importance factor from Table 1604.5 shall be provided for snow,wind,and seismic loads. • IBC 1608.1/Comm 62.1608(2)(a)-For buildings on the same property,where an existing roof is within 15 feet of a proposed taller structure,IBC section 1608.1,or an alternate recognized engineering method,shall be applied to the existing roof,to address any drifting or sliding of snow onto the existing roof,as caused by the taller structure.Where an analysis shows that the existing roof is not adequate to support the additional snow load caused by the taller structure,the existing roof shall be strengthened to support those loads. • IBC 1608.2-Design snow load shall be determined per Chapter 7 of ASCE 7,based on ground snow load of Figure 1608.2. • IBC 1608.4-Sloped roof snow load using the ground snow load Pg per IBC 1608.2, shall be calculated using Section 7.4 of ASCE 7,with the Exposure factor Ce per Section 7.3.1,Thermal factor Ct per Section 7.3.2, snow load Importance factor I per Section 7.3.3 (based on occupancy category per IBC 1604.5),and shall be adjusted by applicable unbalanced loads per Section 7.6, drift loads per Section 7.7 and 7.8,and sliding snow loads per Section 7.9. • IBC 1609.1.1-Wind loads shall be determined per Section 6 of ASCE 7 with the following exceptions: when meeting the limitations of Section 1609.1.1.1, SBCCI SSTD 10(Southern Building Code)may be used for Group R-2 and R-3 buildings,and AF&PA WFCM may be used for residential structures;designs using NAAMM FP 1001 (for flag poles);or designs using TIA/EIA-222 for antenna-supporting structures and antennas. • IBC 1609.3-Basic wind speed of 90 mph for 3 second gust and a 76 mph fastest mile velocity shall be used for design. • IBC 1805.4.1.1-Provide footings which are designed for the most unfavorable effects due to load combinations. Also Address • IBC 1101.1 -The provisions of this chapter shall control the design and construction of facilities for accessibility to people with disabilities. • IBC 1603.1.5-Information required by this code section shall be shown on the construction documents, regardless of whether seismic loads govern the lateral design,ONLY IF the information is required to determine the Seismic Design Category and subsequent analysis procedure[reference IBC 1613.1/Comm 62.1613(1)for exceptions]. See also the exception in s. 1603.1 for buildings constructed in accordance with s. 2308 conventional light frame construction. • IBC 1609.1.1 -Wind loads on building structures shall be assumed to come from any horizontal direction and wind pressures shall be assumed to act normal to the surface considered.
