This webinar was co-sponsored by ASCE's Structural Engineering Institute and ASCE Continuing Education
Purpose and Background
High-rise steel structures represent the ultimate achievement of the structural engineering profession. Many design professionals are interested in discovering how these magnificent structures work and what makes them different from other buildings. Specialized engineering firms, who have accumulated significant expertise in this area and can draw on much previous experience with high-rise issues, typically design tall buildings. The available engineering literature on this subject is written with these specialists in mind and is filled with complex discussions and technical analysis topics.
The purpose of this web seminar is to open this area to the average engineer and provide a practical overview of the issues involved in the design of tall buildings. The presentation starts with a summary of the main topics pertaining to the design of high-rise structures, outlining the typical steel framing and foundation systems. The effects of wind and seismic loads on tall buildings typically greatly exceed those on low and midrise buildings. Accordingly, much of the design differences are in the framing of their Lateral-Force-Resisting Systems (LFRS). The webinar includes a great deal of discussion on these systems and to the case studies illustrating various approaches.
Some other issues that make the design of high-rise buildings challenging include temperature movements, elastic column shortening, fire-protection, and egress. These topics are covered in the presentation as well.
Webinar Benefits
- Understand the various definitions of high-rise buildings and skyscrapers
- Become familiar with the main issues pertaining to the design of high-rise structures
- Learn about the wind effects on high-rise buildings
- Explore the economical ways of designing Lateral-Force-Resisting Systems (LFRS) for steel-framed tall buildings
- Discover how unequal column shortening affects the design of steel skyscrapers
- Examine the foundation systems commonly used in high-rise structures
- Find out how the design challenges were overcome in a variety of situations by discussing several case studies
Assessment of Learning Outcomes
Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and fill in the blank questions).
Intended Audience
Structural and civil engineers, architects, facility managers, and building officials seeking to learn more about the design of high-rise steel structures will benefit from this webinar. The calculations involved are few, easy to follow, and will not to overwhelm those who are not engineers.
