Modern Methods for Learning the Basics of Structural Stability: From Behavior to Practice
To understand the behavior of steel structures, one must understand basic concepts of structural stability.
This course will provide opportunities to achieve that understanding through the use of active learning, which is a novel approach to this AISC Night School Series.
You'll be encouraged to put the fundamentals of structural stability to practice with freely distributed, simple-to-use nonlinear analysis software, or other similar analysis software that you have access to, and compare your results to those presented!
The speakers will also demonstrate how to apply these concepts by reviewing a case study from practice for each topic: compression members, flexural members, beam-columns, and structural systems.
This course is ideal for practicing engineers seeking to establish and/or reinforce their understanding of structural stability and take their learning to the next level by applying it.

Sessions
Session 1: Behavior of Compression Members - The Fundamentals | October 6
OCTOBER 6, 2020, 7:00 P.M. - 8:30 P.M. EDT
Speakers: Ronald D. Ziemian, PE, PhD, and Craig Quadrato, PE, PhD
This session will begin with a brief overview of the 8-lecture course, and its unique format. The behavior of compression members will then be covered. The assumptions in the solution to the Euler column problem will be used as a basis for systematically moving from the theoretical solution presented in 1757 to the modern day methods of design and analysis of compression members. Emphasis will be placed on the effects of material yielding accentuated by the presence of residual stresses, initial imperfections, and end conditions. The flexural buckling strength of members without slender elements will be covered and ultimately presented in the form of column curves. The speakers will conclude by introducing the first learning module.
Session 2: Behavior of Compression Members - Practical Considerations | October 13
OCTOBER 13, 2020, 7:00 P.M. - 8:30 P.M. EDT
Speakers: Ronald D. Ziemian, PE, PhD, and Craig Quadrato, PE, PhD
In this session, the speakers will demonstrate and review/discuss the results of the first learning module on compression members and provide some advice for further exploration. They will then present a case study from practice involving the stability of compression members. They will close out the topic of compression members with some final lessons.
Session 3: Behavior of Flexural Members - The Fundamentals | October 20
OCTOBER 20, 2020, 7:00 P.M. - 8:30 P.M. EDT
Speakers: Ronald D. Ziemian, PE, PhD, and Craig Quadrato, PE, PhD
Using an approach similar to that employed in Session 1, this lecture will provide an overview of the strengths and limitations of the solution to the differential equation that defines the elastic lateral-torsional buckling (LTB) strength of beams. Related flexural and torsional concepts, including the benefits of warping resistance, will be briefly reviewed. The assumption of elastic behavior will then be relaxed to define the inelastic LTB and plastic moment capacities of flexural members. The strength of beams without slender elements will be covered and ultimately presented in the form of beam resistance curves. The speakers will conclude by introducing the second learning module.
Session 4: Behavior of Flexural Members - Practical Considerations | October 27
OCTOBER 27, 2020, 7:00 P.M. - 8:30 P.M. EDT
Speakers: Ronald D. Ziemian, PE, PhD, and Craig Quadrato, PE, PhD
In this session, the speakers will discuss and explore the results of the learning module on flexural members and provide some advice for further study. They will then present a case study from practice involving instability of flexural member. The session will conclude with some final lessons and thoughts on flexural members.
Session 5: Stability of Beam-Columns - The Fundamentals | November 10
NOVEMBER 10, 2020, 7:00 P.M. - 8:30 P.M. EDT
Speakers: Ronald D. Ziemian, PE, PhD, and Craig Quadrato, PE, PhD
This lecture will begin with a review of basic concepts related to the stability of beam-columns. Using thoughts from the lectures on compression members and flexural members, an understanding of the basics of beam-columns will be gained. The speakers will conclude by introducing the third learning module.
Session 6: Stability of Beam Columns - Practical Considerations | November 17
NOVEMBER 17, 2020, 7:00 P.M. - 8:30 P.M. EDT
Speakers: Ronald D. Ziemian, PE, PhD, and Craig Quadrato, PE, PhD
In this session, the speakers will discuss the results of the learning module on beam-columns and provide some advice for further exploration. They will then present a case study from practice involving beam-columns. They will close out the topic of beam-columns with some final lessons.
Session 7: Behavior of Structural Systems - The Fundamentals | December 1
DECEMBER 1, 2020, 7:00 P.M. - 8:30 P.M. EDT
Speakers: Ronald D. Ziemian, PE, PhD, and Craig Quadrato, PE, PhD
This lecture will begin with a review of basic concepts related to the stability of structural systems. With an eye toward design, the difference between a bifurcation or critical load analysis and the loss in stiffness due to second-order effects and material yielding, as the maximum resistance of physical structures is approached, will be emphasized. The lecture will then provide an overview of the direct analysis and effective length methods. The speakers will conclude by introducing the fourth learning module.
Session 8: Behavior of Structural Systems - Practical Considerations | December 8
DECEMBER 8, 2020, 7:00 P.M. - 8:30 P.M. EDT
Speakers: Ronald D. Ziemian, PE, PhD, and Craig Quadrato, PE, PhD
In this session, the speakers will discuss and demonstrate the results of the learning module on systems and provide some advice for further exploration. They will then present a case study from practice involving system stability. They will close out the topic of systems stability with some final lessons and encouragement for further studies aimed at understanding the fundamentals of structural stability by easy-to-use nonlinear analysis.
