2019 SEAONC Fall Seminar: SEAOC Wind Design Manual & Wind Code Update


Thursday, November 7th, & Thursday, November 14th



Come learn about the latest in Wind Design and wind code updates! The SEAOC Wind Design Manual provides practical examples on wind force design for structural elements following ASCE7-16, which is adopted in the 2019 California Building Code. The manual includes 16 example problems in total covering general wind topics, specific topics, buildings and solar PV systems.


Topics include:

  • Overview of ASCE7-16 Wind Chapters and Wind Forces
  • Trends in Wind Codes
  • Wind Design Manual Example problems

Night 1:

            Introduction to the Wind Design Manual and Wind Code Updates

Speaker: Emily Guglielmo, Martin/Martin Consulting Engineers

Introduction to the Wind Design Manual

The Wind Design Manual provides examples on wind force design that illustrate the practical requirements of provisions in ASCE/SEI 7-16.  The introduction will outline the book, including a brief description of each of the problems.

Wind Code Updates

CBC 2019 will adopt ASCE 7-16.  This seminar will outline the major wind changes in ASCE 7-16 that affect the California engineer, including revised wind speed maps and pressure coefficient on low-rise buildings and the introduction of provisions for rooftop equipment on tall buildings, solar PV, and canopies.  In addition, there will be a discussion on the future of wind codes and how engineers can position themselves for these changes.

Main Wind Force Resisting System and Component and Cladding (Problem 6)

Speaker: Emily Guglielmo, Martin/Martin Consulting Engineers

A 60’ tall building in Miami, Florida will be used to illustrate how to generate the Main Wind Force Resisting System (MWFRS) and Component and Cladding (C&C) wind loads using Chapter 27, Part 1 (MWFRS) and Chapter 30, Part 1 (C&C).

PV Problems Wind Forces (Problems 10-13)

Speaker: Karl Telleen, Maffei Structural Engineering

This presentation will cover Wind Design Manual Examples 10 through 13. The examples address low-profile tilted panels on flat roofs (Examples 10 and 11) and flush-mounted panels on sloped roofs (Examples 12 and 13), highlighting new requirements in ASCE 7-16 that followed work by SEAOC’s Solar Photovoltaic Systems Committee. The presentation focuses on concepts behind the requirements and how wind loads on rooftop solar panels are affected by building size and shape, and configuration of the solar arrays.

Night 2:

            Topographic Effects, Exposure Categories and Gust Effects (Problems 2-4)

Speaker: Russell Larsen, Magnusson Klemencic Associates

Topographic Effects

This presentation will cover Wind Design Manual design example 2, Wind Topographic Effects starting with review of why wind speed up effects occur and how wind design pressures are affected by topography.  Next, the ASCE7-22 Topographic method will be discussed in detail with site examples and tricks to easily evaluate topography. 

Exposure Categories

This presentation will cover Wind Design Manual design example 3, focusing exposure category and velocity profile Kz.  The presentation will start with a review of exposure categories and how exposure affects wind speeds at a building site.  The presentation will then demonstrate how a site specific exposure can be computed using ASCE7 methods. 

Gust Effects

This presentation will cover Wind Design Manual design example 4, focusing upon the Gust Factor (G).  The origin and purpose of the Gust Factor for rigid versus flexible buildings will be discussed followed by illustration of the steps used to calculate the Gust Factor. 

            PV Gravity and Seismic (Problem 14 & 15)

           Speaker: John Wolfe, Mar Structural Design

           This presentation will cover Wind Design Manual design examples 14, seismic design of an unattached ballasted solar PV system, and 15, gravity load considerations for existing roofs supporting solar PV arrays. The Structural Commentary for the National Simplified Residential Roof Photovoltaic Array Permit Guidelines will also be introduced as a useful resource for practicing engineers.
