2009 IBC “Alternate Method of All-Heights” Wind Design

Presenter: Ed Huston, PE, SE

Recent trial designs of wind and seismic provisions have shown that practicing engineers have great difficulty applying the wind provisions of ASCE 7-05 and that they often get unconservative answers.  The SEAOC, SEAO and SEAW Wind Committees, in cooperation with NCSEA, have developed a much faster, simpler method for wind design of typical buildings which has been published in the 2009 IBC.  Trial designs of this method indicate that it improves accuracy and greatly reduces the time it takes to calculate the wind forces.
The seminar will provide an overview on the provisions and recommendations for solutions to wind engineering design, especially as those provisions are encapsulated in the traditional method of “All-Heights”.  It will discuss how wind flows around a building and how the flow of wind is taken into account by ASCE 7.  The seminar will provide a comparison of the traditional method of “All-Heights” to the new “Alternate Method of All-Heights” in the 2009 IBC.  The last session of the seminar will present three detailed example problems which compare and contrast the existing and alternate design methods.  These examples include analysis of torsion and topographic effects.
