Keynote

Back to Basics: Simple Things Engineers Know but Sometimes Forget
This presentation addresses some of the concepts engineers know but sometimes forget - as they relate to connection design. Statics, stability and ductility are all briefly addressed.

Larry Muir

9:25-10:00 AM

Connections

Base Plate Design Part One -- Overview and Gravity Loads
The presentation provides an overview of the different elements and materials of base plates including recommendations for fabrication. Base plate loading and the design process for compressive axial force will be covered.

Adam Friedman

10:05-10:35 AM

Connections

Base Plate Design Part Two -- Lateral Loads and Other Topics
The presentation provides an overview of special elements for base plates to resist lateral loads. Design information for tensile axial force, shear force, and moment will be covered.

Adam Friedman

10:40-11:10 AM

Connections

AESS: Spliced by Design
This talk looks at splices in AESS members. Unlike concealed steel where the splices are hidden, splice connections in AESS are on display. There is a variety of ways to approach the intentional downplaying of this necessary connection, to work in concert with the overall detailing of the structure. The use of fully remediated weld splices will be compared to hidden and discreet connections. A variety of real world examples will be referenced.

Terri Meyer Boake

11:15-11:45 AM

Connections

Splice 'n Easy: SSC Perspectives on Member Splices 
Based on questions received in the Steel Solutions Center, the session will review requirements and guidance related to non-seismic and seismic splices to make your next design easier.

Carlo Lini

1:30-2:00 PM

Connections

Girder to HSS Column Connections -- Beyond the Simple
Sure, a shear plate to HSS column is a great, economical connection. But it’s rarely adequate for heavily loaded girders.  This session explores the economics and capacities of the atypical connections where large shear forces are present.

Kim Olson

2:05-2:35 PM

Members

Key Considerations for Lateral-Torsional Buckling
Lateral-torsional buckling occurs when the compression region of a flexural member loaded about its major principal axis buckles laterally while the tension region works to stabilize the member resulting in lateral deflection and twist of the member.  Lateral-torsional buckling will be described and investigated using the AISC beam strength curve for wide flange shapes. Additional considerations including load conditions, end conditions, and warping restraint will also be discussed.

Craig Quadrato

2:40-3:10 PM

Members

Beam Stability Bracing
This presentation will provide information on beam stability bracing, including lateral, torsional and lean-on bracing. Practical issues such as cross-sectional distortion and the height of lateral bracing will be included. The presentation will also include a discussion of the bracing effect of some common types of floor/roof systems.

Bo Dowswell

3:15-3:45 PM

Members

Structural Vibration Serviceability with Finite Element Analysis
The presentation will be an overview of finite element analysis methods in the AISC Design Guide 11 Vibrations of Steel-Framed Structural Systems. Evaluation methods for floors, stairs, and balconies will be introduced. A design example will be presented.

Brad Davis

Lessons Learned

Delegated Connection Design
Delegated connection design can work for everyone! The fabricator and erector can achieve cost effective connections and the EOR can utilize a Performance Specification leaving it to the contractor to accomplish components of the steel design. The foundations that make delegated connection design successful will be featured as well as potential problems and lessons learned so that the benefits of delegated design can be constantly achieved.

Carol Drucker

9:25-10:00 AM

Lessons Learned

Groundbreaking Buildings
Over several decades, the speaker has successfully overcome design challenges by creating new approaches ranging from inventing new structural systems to advanced construction methodology to seismic isolation. This session highlights the lessons learned during these projects including the discovery of the almost limitless ways steel can be used.

Jon Magnusson

10:05-10:35 AM

Lessons Learned

Stability of Steel Structures
Stability design of steel structures has advanced over time. The speaker will share lessons learned from decades of designing unique bridge and building projects. Through consideration of stability and challenging the state of the art, innovative designs were made possible

Shankar Nair

10:40-11:10 AM

Lessons Learned

The Tragic Collapse of KTVO Tower
During a planned repair of the 2000-foot tall KTVO tower near Kirksville, Missouri, the tower catastrophically collapsed without warning. The collapse resulted in loss of life as well as a complete loss of the tower structure. The story begins when the steel tower was being repaired due to potentially defective bracing. In an effort to expedite the repair process, the construction crew performing the repair altered the engineering guidelines for temporary internal bracing while repairing the defective bracing. The unique tower geometry and placement of guy-wiring, as well as material inconsistencies of the tower components, contributed to the necessity and sequence of the repair operation. Furthermore, resulting in local instabilities which ultimately led to a global twist and subsequent collapse of the system are also discussed.

Cliff Bishop

11:15-11:45 AM

Lessons Learned

Seismic Design of Steel Buildings
Published building codes and design examples provide a sound fundamental framework for seismic design, but they do not necessarily prepare you for everything. This session covers lessons learned from the design of stadiums, arenas, and other large and complex structures in high seismic areas.

Rafael Sabelli

1:30-2:00 PM

Good, Bad, & Ugly

Welded Connections
What makes for a good welded connection? What makes one bad-or just plain ugly? This webinar explores 12 principles of welded connection design that answer these questions. The principles will be explained and illustrated with good, bad, and ugly examples. Developed with the Engineer and Detailer in mind, this presentation will be of interest and value to Fabricators and Erectors as well.

Duane Miller

2:05-2:35 PM

Good, Bad, & Ugly

Constructability
This session will help the engineer in their decision making process when designing steel buildings. Based on his extensive experience and close work with fabricators and erectors, the speaker will show the good, bad, and ugly of constructability when it comes to efficient framing schemes, economical connections, and fabricator/erector friendly design solutions.

Jason Perry

2:40-3:10 PM

Good, Bad, & Ugly

Connection Design
Where to find the Good, how to avoid the Bad, and get a peek at the Ugly when it comes to structural steel connection design.

Steeling the Future
As we sit here in our home offices, we can’t help but contemplate what the future will reveal. Whether we foretell a dystopian or utopian future, the role of civil engineering (and steel construction in particular) will remain critical. All the visions of the future, whether foretold by Issac Asimov or by George Lucas, include high-rise steel construction. This presentation will offer a glimpse into the near future of high-rise building construction using structural steel as the material and system (SpeedCore) of choice. The presentation will also look further into the future where 3D printing, robotics, and advanced methods of manufacturing will play an important role.
