Design of Curved Members / Facade Attachments

Design of Curved Members

Although the structural behavior of curved members can be much different from their straight counterparts, the Design Guide provides recommendations for using the AISC Specification equations for straight members to design curved members. This “equivalent straight member” method will allow the use of existing commercial software for curved member design by modifying effective length factors and lateral-torsional buckling modification factors to account for the curvature.

Guidance for Supporting Facades on Steel-Framed Buildings

The attachments of modern facade systems to the primary building structure can present some of the most difficult challenges on any building.  It involves a number of different parties—the owner, the architect, the structural engineer, the building envelope consultant, and many different contractors—coming together to create a facade that achieves aesthetic, thermal, air infiltration, and moisture objectives.  This course will provide guidance for practicing structural engineers, architects, and contractors on how to navigate this aspect of a building’s design that is vitally important but often given less attention than it deserves.

Sessions

Presented by Bo Dowswell, PhD, PE

This session presents general information on curved members including an overview to the coming soon AISC Design Guide.  The session will introduce the attendees to bending geometries, bending processes, and considerations for design for bending: curving mechanics, fracture during bending and distortion.  Additional design considerations, tolerances contract documents and more, are also discussed.

Presented by Bo Dowswell, PhD, PE

This session addresses the treatment vertically-curved members.  Topics include axial strength, flexural strength, combined axial and flexural loads, local strength and connections

Presented by Bo Dowswell, PhD, PE

The session addressses the treatment of horizontally-curved members. Topics include: flexural strength, torsional strength, combined flexural and torsional loads, serviceability, local strength and connections.

 

Presented by Bo Dowswell, PhD, PE

This session will present a design example for vertically-curved members.  In addition to demonstration the design of the member, the example will address the design of the connection.  Then, the session will present a design example for horizontally-curved members. In addition to demonstration the design of the member, the example will address the design of the connection. 

Session 5: Facade Fundamentals

Presented by Alec Zimmer, PE, SECB

This session addresses the following topics:

  • Fundamentals of Facade Performance
  • Design Criteria
  • Design and Execution Responsibilities
  • Thermal Separations
  • Accommodating Tolerances

Session 6: Facade Attachments, Part 1

Presented by Alec Zimmer, PE, SECB

This session will presents the following topics:

  • Design of Steel-Framed Slab Edges for Facade Attachments
  • Design of Steel Spandrel Beams
  • Attachment of Masonry Cavity-Wall Systems

Session 7: Facade Attachments, Part 2

Presented by Alec Zimmer, PE, SECB

This session will presents the following topics:

  • Attachment of Aluminum-Glass Curtain Walls
  • Attachment of Panelized Facade Systems
Presented by James Parker, SE

When a building frame is designed to drift, it must still support the facade that is attached to it. In single-story buildings, this could mean allowing the frame to drift parallel to the facade, with a lateral connection to the facade for out of plane loads. In multi-story buildings, the facade is supported on a frame that moves. How does the engineer work with the architect to ensure the two work together? What does the structural engineer need to know about the strategies for accommodating drift in the facade? How do various facade systems and their attachments affect the engineer's design of the frame and spandel details?
