In Wind Loading Fundamentals: How to Design Wind-Resistant Buildings and Structures, you'll learn ...
- The nature of wind and how it interacts with buildings and structures
- The ASCE/SEI 7-10 general requirements for structural design of buildings and other structures
- How to analyze and account for wind loads in the design of buildings and other structures
- The nature and impact of hurricanes and tornadoes—and how to design for them
Overview
This webinar teaches both fundamental and advanced concepts of wind engineering for engineers and other professionals who have little or no background in the design and analysis of wind loads. Through live interaction, webinar participants will become familiar with general concepts of wind engineering and wind design criteria, as well as the American Society of Civil Engineers Standard: ASCE/SEI, 7-10 Minimum Design Loads for Buildings and Other Structures.
We will look at the minimum wind design loads and design formulae in a simplified format, making them easy to understand and apply. You will learn how to analyze important parameters and perform calculations for determining wind loads on buildings (using, for example, the directional procedure), and various design examples will help you determine wind pressures for other structures, such as rooftop equipment and billboard signs. You will also learn the effects of extreme winds generated by hurricanes and tornadoes and how to employ multi-protection design to mitigate the damage caused by such natural disasters.

How Webinars Work
It's easy ... and it doesn't take a computer guru to figure it out. At the time of the webinar, you connect to the internet and call in to a toll-free number. You see the presentation on your computer screen. You hear and talk through the telephone. It's just like being there without all the hassle. There's no travel expense and no wasted time in the car.
System Requirements
To attend this webinar, you'll need a computer with a high-speed internet connection (DSL or cable) and a phone line. For your comfort, it is recommended that you use a speakerphone or headset to connect to the webinar. Our system will support both PC's and Apple computers using Internet Explorer, Firefox, Chrome or Safari browsers. If you select a site license, you must provide projection of the internet onto a viewing screen or have a monitor large enough for the group to see.
Registration Deadline
Online registration is available until the scheduled start of the webinar (subject to seat availability). However, we suggest that you register early as webinars fill up quickly. For questions, call our Customer Service Team toll-free at 1-877-PDHengineer.
Accessing the Webinar
