Wind Loads

The information presented here follows the '94 UBC guidelines 1613 through 1623 and the '97 UBC 1615-1625. These requirements may be applied to buildings with H/W < 5 and H < 400 ft. In addition, for one or two story masonry buildings in seismic zones 0, 1, or 2 with basic wind speeds from 80 - 110 mph, refer to the Appendix Chapter 21 of the UBC titled "Prescriptive Masonry Construction in High Wind Areas".

Topic Directions:
Two class days will be devoted to this wind load topic and related project activities. To complete this topic you need to:
  1. Study the four sets of on-line lecture notes.
  2. Complete the reading assignment.
  3. Come to each class period prepared to discuss the following material:
    • Day 1 - Wind pressure, building stability, and drift.
    • Day 2 - Example and Project.
  4. Complete the various problem assignments and submit for grading only those assignments designated as such:
    • Wind pressure and stability.
    • Analysis: Submit on day 3.
  5. Complete the wind load phase of the design project and submit as directed in the project area of this class.

On-Line Lecture:

Reading Assignment:
  • Breyer, Chapter 2, Sections 2.9 - 2.11.
  • Breyer, Chapter 3, Sections 3.3 - 3.5.


Problem Assignment:
Complete the following problem sets using the calculation procedures outlined in the lecture notes and by Breyer.
