ASCE 7-16 Wind Provisions – Changes Affecting the Design Provisions

November 14, 2018 @ 12:30 pm – 2:00 pm

Speaker: Don Scott, S.E.

PCS Structural Solutions

This SE University session will review the changes to the ASCE 7 Wind Load Provisions that were adopted in the 2016 edition that is referenced in the 2018 IBC. Some of the changes that have the greatest impact on the design provisions are new Wind Speed Maps used in design, the inclusion of an Elevation Factor, and new Roof Pressure Coefficients. The presentation will explain the background of the new provisions to help engineers understand how and when to use these new provisions in their designs.

Learning Objectives

After participating this session, the learner will be able to:

  • Understand the basis of the new wind speed maps
  • Be able to determine the design wind speed at their site using more than one method
  • Understand the basis of the changes to the Roof Pressure coefficients for low-rise flat and sloped roofs
  • Understand the effect the use of the new Elevation Factor has on their design.

Handouts and registration emails will be sent to SEU companies on Friday, November 9th.
