Wind Loads – 4 Part Series - CD Seminar (0.4 CEUs)

Wind Loads – 4 Part Series! - CD Seminar

James M. Delahay is the President/CEO of LBYD, Inc., a 45-person consulting structural and civil engineering firm in Birmingham, Alabama. Delahay received both his BS and MS degrees in Civil Engineering from the University of Alabama. He has been a member of the ASCE Committee 7 on Minimum Design Loads For Buildings and Other Structures and the ASCE 7 Task Committee on Wind Loads since 1996. Delahay is currently serving as the vice-chairman of the Wind Load Committee.

From 1999 to 2002, Delahay served on the Structural Committee of the International Building Code, as one of three practicing engineers representing the National Council of Structural Engineer’s Associations (NCSEA). In 2002, he was elected chairman of that committee, the first practicing engineer to hold the position. He is also the chair of the NCSEA Code Advisory Committee, which represents the interests of structural engineers to the Building Code development community.

Delahay has presented numerous seminars nationwide on both the IBC and ASCE wind load provisions. Venues have included ASCE Structures Congresses and Annual Conferences, NCSEA Annual Conferences, the 2001 NCSEA Winter Institute, and national seminar tours with S.K. Ghosh & Associates.

Course Description

Designing structures to resist wind has changed drastically over the last ten years. It seems to have gotten more and more complex, however much of that perception is caused by a lack of understanding of basis of the equations and graphs that you see in the Code. Much of the mystery can be removed by spending just a few hours looking at the background and basis of today’s wind load provisions. That look behind the equations will increase the your intuition about how to properly apply the provisions.

That information, along with an overview of the provisions and example problems are presented in this four part series of one-hour, web seminars. The series is designed for engineers, architects and building officials who need to understand the latest requirements in wind loads. The newest building codes (IBC, NFPA, and Florida) reference the wind provisions of ASCE 7 Standard – Minimum Design Loads for Buildings and Other Structures. Chapter 6 – Wind Loads from the 2002 edition will be the basis for this series.

SEMINAR 1:
Background and Basics
Turning weather into design pressures

We all hear the weather predictions every day, but how does weather relate to the forces we design structures for? Understanding a few of the basic concepts from meteorology can give great insight into the basis for wind loads. A quick review of some aerodynamic effects shows why wind loads vary from building to building because of their shape. The combination of meteorology and aerodynamics results in the general equation of wind that is the basis for all modern wind provisions. This seminar-on-CD takes the mystery out of those components of wind engineering.

SEMINAR 2:
An Overview of ASCE 7-02 Wind Loads
How the provisions work

Opening Chapter 6 of the Standard can be overwhelming. There are three methods - which do you use? There are low-rise and high-rise provisions – what are the differences between them? Why are there different pressures for frames versus cladding? Part two of this series answers those basic questions and explains the pieces of the puzzle such as:

Basic Wind Speed Maps and Importance Factor
Directionality Factor, Exposure Factor, and Topographic Factor
Pressure Coefficients for Main Wind Force Resisting Systems and Components and Cladding
ASCE 7’s Wind Equations

SEMINAR 3:
Designing Buildings by the Traditional ASCE 7 Procedure

The traditional procedure for determining wind pressures on a structure has actually not changed that much over the last 30 years. There have been improvements to some of the factors used, but the equations in this “traditional” method are still basically the same. A few examples using this procedure will help to reinforce the lessons learned in parts one and two of the series.

SEMINAR 4:
Other Options for Designing Buildings for Wind Loads

Recent editions of ASCE 7 have added alternative methods for determination of wind loads for certain types of buildings. The Simplified Method is a very quick and easy way of figuring wind loads, and it applies to a very common group of buildings. Learning how to effectively use this method can greatly increase your design efficiency. Also, the low-rise procedure is available for an even larger family of buildings and yields very accurate answers, for those seeking an optimum solution. A few examples of these new alternative methods are presented in this fourth and final installment of the series.

Comments on Webinar

"It is a great format. It allows many of us to gather in the conference room during lunch hour to attend the seminar in a very efficient and limited timeframe. The hour length is fantastic. It fits into our brown bag lunch seminar plan."

"In an environment where time management is so crucial, it is wonderful to be able to attend a meaningful seminar with such little ancillary time commitments such as travel and coordination. My compliments. ASCE has found the perfect seminar format for today's busy professional."
