Basic Steel Design: A review of the principles of steel design according to ANSI/AISC 360-16

This course will consist of eight 1.5-hour sessions and is intended as an introduction and review of the basic principles of structural steel design. It is best suited for those who have not designed in structural steel for some time or those who feel a basic review will improve their overall capabilities. Session 1 will include an introduction to structural safety and the principles of LRFD and ASD design, loads and load combinations, the AISC Specification and structural analysis. Session 2 will address tension member design. Sessions 3 will treat compression members. Session 4 will address bending members and session 5 will consider combined axial forces and bending. Session 6 will treat stability analysis and design principles and second-order analysis. Session 7 will address the effective length method and the direct analysis method. Session 8 will discuss composite beam design.

All completed examples will be presented in both ASD and LRFD in the handout material although the presentation may only discuss one or the other approach. The AISC Steel Construction Manual, 15th edition is a highly recommended text for this class. The presentation will make reference to specific sections of the Specification, examples will use data taken from the manual, and the use of design tables will be illustrated. The author's textbook Unified Design of Steel Structures, third edition, 2017, written with co-authors Judy Liu and Charles Carter, will form the basis of this course and may be a useful resource for building on the course.

Louis F. Geschwindner, PE, PhD

This lecture will begin with a brief overview of the 8-session course. Next a brief history of the Specification and Manual will be provided as well as an overview of the organization of the current Specification and Manual. The lecture will then discuss the elements of structural safety with an emphasis on the principles of LRFD, variability of load effect and variability of strength. Resistance factors for LRFD and safety factors for ASD will be discussed as well as calibrating ASD to LRFD. The session will discuss steel as a material, various steel shapes, and introduces 1st and 2nd order structural analysis.

Session 2: Tension Members

Louis F. Geschwindner, PE, PhD

This lecture will focus on the design of structural steel tension members and the associated provisions in the AISC Specification.  The session will begin with a discussion of strength, calculating area and available strength of tension members.  Emphasis will then be placed on designing tension members before discussing the concept of block shear.  The session concludes with an overview of eyebars, pin connected members, truss members and braces.  Several design examples will be presented.

Session 3: Compression Members

Louis F. Geschwindner, PE, PhD

The design of columns – compression members, is the focus of this session. The session will review the strength of compression members as defined by the Specification. The session will review steel shapes and their behavior in compression. The session will discuss the limit states of flexural buckling, local buckling, torsional buckling, and flexural-torsional buckling. Members with and without slender elements are reviewed. Design examples will be presented.

Session 4: Bending Members

Louis F. Geschwindner, PE, PhD

This session will discuss the design of structural steel beams and application of Chapter F of the AISC Specification. The session will review plastic vs. elastic moment strength and the various limit states of bending members. The lecture will address Cb, the lateral-torsional buckling modification factor for non-uniform moments diagrams and its effect on beam designs. The session will also review the design of single angles and WT shapes. Design examples will be presented.

Session 5: Compression + Bending

Louis F. Geschwindner, PE, PhD

This lecture will discuss the behavior and design of beam-columns. The session will review elastic and plastic interaction principles, AISC interaction equations and design rules of thumb. The session will explore the design of members in single axis bending as well as the design of single angles for bending plus compression.

Louis F. Geschwindner, PE, PhD

Part I of this 2-session lecture on Stability Analysis and Design will review the five stability requirements to be considered in design. The session will review required strength and available strength. The session will then discuss 2nd order analysis and demonstrate how methods to calculate 2nd order effects by hand. This will include presenting the development of the B1-B2 method discussed in the AISC Specification, Appendix 8 – Approximate Second-Order Analysis.

Louis F. Geschwindner, PE, PhD

Part II of this 2-session lecture continues to explore the requirements of the AISC Specification for the design for stability. The session will discuss and demonstrate the Effective Length Method through examples. The session will then highlight the Direct Analysis Method and discuss the advantages of the method; specifically, that the Direct Analysis Method allows the use of a K-factor equal to 1.

Louis F. Geschwindner, PE, PhD

This session examines the principles of composite action. The lecture will review elastic vs. plastic behavior and the influence of steel deck on composite members. The session will discuss the design of composite beams including determining steel-headed stud anchor strength and placement, deflection, and economy in shape selection. The session will conclude with a review of the encased and filled composite members.
