Minor Ph.D., P.E., F.ASCE Dr. Minor is Consulting Engineer and Visiting Professor, Texas, A & M University-Kingsville. His specialty includes wind-structure interaction, effects of extreme winds on buildings, code provisions for wind loads and the economics of wind-resistant construction. He has conducted extensive research on window glass behavior under the effects of wind pressure, blast loading, and impact from wind borne debris and hailstones. Dr.Minor serves on the Windstorm Building Code Advisory Committee to the Texas Department of Insurance. In 1978, he was appointed a Fulbright Senior Scholar in Australia where he conducted an assessment of research and practice in natural hazards management. Dr. James R. McDonald, Ph.D., P.E., F.ASCE Dr. McDonald is former Chairman and Professor of Civil Engineering at Texas Tech University. Dr.McDonald has specialized in research related to the wind-structure interaction produced by extreme windstorms. His assessment of hazard probabilities for nuclear facilities is widely used by the industry. He has researched methods for improving the wind resistance of low-rise structures and has developed techniques for evaluating existing buildings for their potential performance in high winds. He is frequently consulted regarding retrofit strategies for existing structures. Dr. McDonald has served on the ASCE 7 Committee on Wind Loads that produced ASCE 7-98. He is one of the principals in the firm McDonald- Mehta Engineers.

Course Description In recent years the migration of people to the hurricane-prone coastline, general increase in the urban sprawl in the middle of the country,and the development of new high-tech,lightweight,building materials have increased the incidence of building disasters, and wind damage. Hurricanes Andrew (1992), Iniki (1992), Hugo (1989), four hurricanes of 2004, hurricanes Katrina, Rita and Wilma of 2005 and the Kansas-Oklahoma tornado outbreaks (1999 & 2003) were catastrophic demonstrations of the increasing vulnerability of buildings and other structures (tanks, signs, towers, etc.) to severe wind storms. Wind induced property losses now annually exceed the sum of all other losses from natural hazards. This seminar addresses wind effects, provides guidelines for assessing design wind loads for buildings and other structures, and offers a discussion of the advantages of wind tunnel testing.This seminar is based on the ASCE publications “Minimum Design Loads for Buildings and Other Structures (ASCE 7)”and “Guide to the Use of the Wind Load Provisions.”While much of the instruction focuses on assessing wind loads,a portion of the seminar is directed to review wind damage experience of the past thirty years and lessons learned from the experience. DAY ONE of this seminar is devoted to a comprehensive review of basic wind engineering fundamentals and the background of the wind load provisions of the national standard, ASCE 7- 05 (approved in 2005). DAY TWO focuses on the application of national standard ASCE 7-05 with hands-on experience gained by working through a number of examples utilizing provisions of ASCE 7-05. A portion of the day includes going beyond the standards.Even though the latest standard ASCE 7-05 is used in the seminar, the discussion is valid for the standards ASCE 7-95, 7-98, and 7-02. The fundamental goals of the seminar are: To give you engineering understanding of wind and wind effects on buildings and structures To give you background and intent of the provisions of of ASCE 7-98, 7-02 and 7-05. To allow you to use provisions of ASCE 7-05 with correct interpretation to assess wind loads on buildings and structures To provide you with understanding of relationship between ASCE 7 and IBC wind load provisions By attending this seminar you will: Gain an in-depth understanding of ASCE 7-05 wind load provisions and wind effects on buildings and other structures Discuss interpretations and limitations of key provisions of ASCE 7-05 Discuss how to use the provisions of foreign codes and standards Have an opportunity to ask questions and discuss solutions with the experts who developed the wind load provisions in the national standard and who have over 30 years of experience dealing with wind effects Interact with participants from across the country to share knowledge of wind resistant design

Attendees’ Comments

“The course is an in-depth review of where wind loads standards came from and how to apply them to practice.”
-James Baker, O’Donnel Naccarato & MacIntosh, Wilmington, DE

“This course did a great job of recovering information spanning the historical background of wind loads provisions, key aspects of the current codes, and future revisions. I would highly recommend this course to others.”
-Jeff Mitchell, P.E., HDR Engineering, Inc., San Antonio, TX

“Excellent background on development of wind section of ASCE-7 wind load criteria.”
-Sean Cochran, P.E., Chicago Bridge & Iron, Woodlands, TX

“The course exceeded my expectations on theory of wind loads.”
-Tracy Mitchell, President, SDD Corporation, Cincinnati, OH

“I found the course to be enlightening. It shed light on how the factors used in standards were determined. I think most engineers use them without a thought as to where they come from.”
-Bart Barrett, Nelson Architectural Engineers, Dallas, TX

“The theory and history behind the standard is invaluable to the engineer required to make sound judgment calls.”
Tom Kuckhahn, Director of Engineering
