Design of Built-up Plate Girders based on AISC 360-16 Specification for Structural Steel Buildings

There are many situations in flexural member design where the geometrical or loading conditions require the engineer to look beyond standard rolled wide-flange shapes.

One solution for such cases is built-up plate girders, which introduce their own design challenges related to section slenderness that engineers rarely encountered when working with rolled shapes. Join us for a two-part webinar to learn how to apply the provisions of AISC 360-16 Specification for Structural Steel Buildings, Chapters F and G, to design built-up plate girder members for the effects of bending and shear.

Session 1 – Bending (July 22, 2021)

The first session in this two-part webinar will focus on designing built-up plate girders for bending moments. We'll discuss plate girders with noncompact or slender webs and both doubly and singly symmetric cross-sections. The lesson will explore how the Specification accounts for local buckling by using reduction factors to modify the strengths determined from commonly considered limit states of yielding and lateral-torsional buckling.

Session 2 – Shear (July 29, 2021)

The second session in this two-part webinar will focus on designing built-up plate girders for shear. The lesson will compare the two approaches that the Specification uses to determine shear strength: rotated stress field theory and tension field action theory. We'll cover the design of both transverse and bearing stiffeners as well as the connection between web and flange plate elements.
