For SI: Ma = qhCLbLLa(1.0 - GCp) / 1,000
 
where:
 
b =       Exposed width, feet (mm) of the roof tile.
 
CL =       Lift coefficient. The lift coefficient for concrete and clay tile shall be 0.2 or shall be determined by test in accordance with Section 1716.2.

The point of uplift shall be taken at 0.76L from the head of the tile and the middle of the exposed width. For roof tiles with nails or screws (with or without a tail clip), the axis of rotation shall be taken as the head of the tile for direct deck application or as the top edge of the batten for battened applications. For roof tiles fastened only by a nail or screw along the side of the tile, the axis of rotation shall be determined by testing. For roof tiles installed with battens and fastened only by a clip near the tail of the tile, the moment arm shall be determined about the top edge of the batten with consideration given for the point of rotation of the tiles based on straight bond or broken bond and the tile profile.
 
Ma =       Aerodynamic uplift moment, feet-pounds (N-mm) acting to raise the tail of the tile.
 
qh =       Wind velocity pressure, psf (kN/m2) determined from Section 6.5.10 of ASCE 7.
 
Concrete and clay roof tiles complying with the following limitations shall be designed to withstand the aerodynamic uplift moment as determined by this section.
 
1.      The roof tiles shall be either loose laid on battens, mechanically fastened, mortar set or adhesive set.
 
2.      The roof tiles shall be installed on solid sheathing which has been designed as components and cladding.
 
3.      An underlayment shall be installed in accordance with Chapter 15.
 
4.      The tile shall be single lapped interlocking with a minimum head lap of not less than 2 inches (51 mm).
 
5.      The length of the tile shall be between 1.0 and 1.75 feet (305 and 533 mm).
 
6.      The exposed width of the tile shall be between 0.67 and 1.25 feet (204 and 381 mm).
 
7.      The maximum thickness of the tail of the tile shall not exceed 1.3 inches (33 mm).
 
8.      Roof tiles using mortar set or adhesive set systems shall have at least two-thirds of the tile's area free of mortar or adhesive contact.

1613.5.3 Site coefficients and risk-targeted maximum considered earthquake (MCER) spectral response acceleration parameters. The MCER spectral response acceleration parameters for short periods, SMS, and at 1-second period, SM1, adjusted for site class effects shall be determined by Equations 16-47 and 16-48, respectively:
 
SMS = FaSS                                                            (Equation 16-47)
 
SM1 = FvS1                                                      (Equation 16-48)

Fv =       Site coefficient defined in Table 1613.5.3(2).
 
SS =       The mapped MCER spectral accelerations for short periods as determined in Section 1613.5.1.
 
S1 =       The mapped MCER spectral accelerations for a 1-second period as determined in Section 1613.5.1.
 
§21. Sections 1613.5.4 and 1613.5.5 of the New York city building code, as added by local law number 141 for the year 2013, are REPEALED and new Sections 1613.5.4 and 1613.5.5 are added to read as follows:
 
1613.5.4 Design spectral response acceleration parameters. Five-percent damped design spectral response acceleration at short periods, SDS, and at 1-second period, SD1, shall be determined from Equation 16-49 and 16-50, respectively:
 
SDS = 2/3SMS                                                 (Equation 16-49)
 
SD1 = 2/3SM1                                                 (Equation 16-50)
 
 
where:
 
SMS =       The MCER spectral response accelerations for short period as determined in Section 1613.5.3.
 
SM1 =       The MCER spectral response accelerations for 1-second period as determined in Section 1613.5.3.
 
1613.5.5 Site classification for seismic design. Site classification for Site Class C, D or E shall be determined from Table 1613.5.5. The notations presented below apply to only materials encountered above rock meeting Class 1a, 1b, or 1c as defined in Section 1804 or rock with shear wave velocity greater than 2500 feet per second (762 meters per second) to a maximum depth of 100 feet (30 480 mm). Profiles containing distinctly different soil and rock layers shall be subdivided into those layers designated by a number that ranges from 1 to n at the bottom where there is a total of n distinct layers in the upper 100 feet (30 480 mm). The symbol i then refers to any one of the layers between 1 and n.
 
where:
 
vsi =       The shear wave velocity in feet per second (m/s).
 
dI =       The thickness of any layer between 0 and 100 feet (30 480 mm).
 
(Equation 16-51)
 
where:
 
Ni is the Standard Penetration Resistance (ASTM D1586) not to exceed 100 blows/foot (328 blows/m) as directly measured in the field without corrections. When refusal is met for a rock layer of Class 1d, Ni shall be less than or equal to 100 blows/foot (328 blows/m) provided that the extend of the Class 1d material is confirmed by a boring to a depth where Class 1c or better rock is determined, not to exceed 100 feet. Alternatively, if this boring is not performed, site classification should be based on all soil material that is above the Class 1d layer.
 
(Equation 16-52)
 
 
(Equation 16-53)
 
where:
 
 
 
Use di and Ni for cohesionless soil layers only in Equation 16-42.
 
ds =       The total thickness of cohesionless soil layers in the top 100 feet (30 480 mm).
 
m =       The number of cohesionless soil layers in the top 100 feet (30 480 mm).
 
Sui =       The undrained shear strength in psf (kPa), not to exceed 5,000 psf (240 kPa), ASTM D 2166 or D 2850.
 
 
 
where:
 
 
 
dc =       The total thickness (100-ds) (For SI: 30480-ds) of cohesive soil layers in the top 100 feet (30 480 mm).
 
k =       The number of cohesive soil layers in the top 100 feet (30 480 mm).
 
PI =       The plasticity index, ASTM D 4318.
 
w =       The moisture content in percent, ASTM D 2216.
 
Where a site does not qualify under the criteria for Site Class F and there is a total thickness of soft clay greater than 10 feet (3048 mm) where a soft clay layer is defined by su < 500 psf (24 kPa), w > 40 percent, and PI > 20, it shall be classified as Site Class E. The shear wave velocity for rock, Site Class B, shall be either measured on site or estimated by a geotechnical engineer or engineering geologist/seismologist for competent rock with moderate fracturing and weathering. Softer and more highly fractured and weathered rock shall either be measured on site for shear wave velocity or classified as Site Class C. The hard rock category, Site Class A, shall be supported by shear wave velocity measurements either on site or on profiles of the same rock type in the same formation with an equal or greater degree of weathering and fracturing. Where hard rock conditions are known to be continuous to a depth of 100 feet (30 480 mm), surficial shear wave velocity measurements are permitted to be extrapolated to assess vs. The rock categories, Site Classes A and B, shall not be used if there is more than 10 feet (3048 mm) of soil between the rock surface and the bottom of the spread footing or mat foundation.
