The following example, adapted from standard engineering practice, illustrates the complete procedure.
This factor accounts for the loading effects of wind turbulence and the structure's dynamic response. For most rigid buildings (fundamental natural frequency > 1 Hz), the code allows the use of a simplified value of .
Before computing final pressures, compute ( q_h ) using the same formula as ( q_z ) but evaluated at the mean roof height ( h ):
[ p = q , G , C_p - q_h (GC_pi) ]
For z≤zmin∶Kz=2.01⋅(zminzg)2/αFor z is less than or equal to z sub m i n end-sub colon cap K sub z equals 2.01 center dot open paren the fraction with numerator z sub m i n end-sub and denominator z sub g end-fraction close paren raised to the 2 / alpha power
ASCE 7-05 contains three design methods for wind load calculation. ASCE 7-10 expands this to six primary design approaches applicable to roof systems and other building elements.
To successfully navigate the following equations, a clear understanding of the fundamental parameters defined by the code is necessary. A thorough comprehension of these definitions is crucial for accurate application.
