Devil in the Details II – Delving Deeper into Delegated Design
Don Allen, P.E., Director of Engineering
Super Stud Building Products, Inc.

In this follow-up to the initial 'Devil in the Details' seminar and webinar, Don Allen gets a bit more technical: giving the hows and whys for proper detailing and coordination of cold-formed steel.  From out-of-tolerance concrete to how to properly distribute loads to shearwalls to where and how to properly allow for structure movement, this presentation gives practical solutions to proper detailing of cold-formed steel, and tips for the specialty engineer, Engineer of Record, and architect.  With no shortage of devilish details from his 25+ years in CFS design, Allen shows designers how to avoid/fix these details in the drawings they produce, and shows contractors and specialty engineers what to do when these details appear in contract documents.

Over the past quarter-century, Don Allen has helped many engineers, contractors, manufacturers, code officials, and even architects understand both the complexities of the code requirements and the field installation issues of structural and nonstructural cold-formed steel. Having served over nine years as Technical Director for both the Steel Framing Alliance (SFA) and the Cold-Formed Steel Engineers Institute (CFSEI), Allen has seen firsthand how some designs have been successful while others have been disastrous because of good or bad detailing and analysis. Allen has participated in the development of the International Building Code (IBC), and ASTM and American Iron and Steel Institute (AISI) standards.  Currently, Allen is Director of Engineering for Super Stud Building Products, Inc., and Chairman of AISI's Education Committee. Allen is a Registered and Board Certified Structural Engineer, and a LEED Accredited Professional.

Multi-Story Load Bearing Cold Formed Systems – Making the Best Decisions
Cody L. Dailey, M.S., P.E., S.E., McClure Engineering Company

The presentation will provide a background of nearly all types of load bearing cold formed systems.  Various floor systems, lateral systems, and wall systems will be discussed including pros/cons and details of construction.  It will provide a toolkit for making the right design decisions and selecting the proper system for a specific building type and size.  It will strive to answer the following questions:

  • What are the pros and cons of each type of flooring system including structural performance and architectural criteria?
  • What is the optimal bearing wall arrangement for various building sizes and types?
  • Flexible vs rigid diaphragms.  Concrete vs gypcrete?
  • Lateral systems – straps vs sheet steel?  What if I have CMU shafts?
  • Brick relief and other special details?
  • What are the pitfalls when my building is 7-10+ stories tall?

Cody L. Dailey is currently the Director of Structural Services for McClure Engineering Company based in Missouri and Iowa and practicing in 36 states. He has over 13yrs experience designing cold formed systems throughout the country. He has a background specifically in non-bearing exterior framing, curved structural cold formed, multiple types of load bearing floor systems, panelized construction, tall multi-story (10+) drift controlled cold formed-hybrid lateral systems, blast resistant cold formed, and DOD progressive collapse.

Cold-Formed Steel Kneewall Design
Hien Nguyen, M.S., P.E.
Simpson Strong-Tie Company Inc.

The International Building Code (IBC) requires structural systems and members to be designed with adequate stiffness to limit deflections and lateral drift. Specifically, IBC Table 1604.3 provides deflection limits for various construction applications to which the registered design professional must adhere.

There are several types of connectors that help provide rotational resistance at the base of exterior cold-formed steel (CFS) kneewalls, parapets, handrail and guardrail systems as well as interior partial-height walls.  While they are somewhat similar, there are some differences for which understanding is necessary to ensure proper code compliance and performance of these systems.

This presentation will explore CFS kneewall connectors, including various installation optionsincluding the pre-fabbed steel posts.  It will also examine testing criteria and rotational stiffness determination as well as the design process considering various limit states.  Many of the challenging questions regarding anchorage design and options will also be discussed.

Hien Nguyen is a Research and Development Engineer for Simpson Strong-Tie Company Inc. in Pleasanton, California.  A new product development specialist, Mrs. Nguyen has over 17 year experience in structural connector design. While still working on connector projects for wood construction, her skills and passion for cold-formed steel (CFS) construction have propelled her expertise in CFS product development.  She also has been a contributor towards the development of several AISI test standards as well as for the CFSEI “Cold-Formed Steel Framed Wood Panel or Steel Sheet Sheathed Shear Wall Assemblies Design Guide” which was published in 2009. Before joining Simpson Strong-Tie, Mrs. Nguyen worked as a consulting design engineer for various building projects. She has a Bachelor of Science in Civil Engineering from UC Davis, a Masters degree from San Jose State University and is a registered California Civil Engineer.

The Challenges of Delegated Design on the Cold-Formed Steel Specialty Engineer
Jamie John, E.I.T.
Excel Engineering

As cold formed steel specialty engineers common challenges exist for projects with delegated design.  The result is “voids” in the cold-formed steel shop drawings where information simply is not available.   Without proper information, it is challenging to design the cold formed steel properly.  Examples would include: trusses, curtainwalls, storefronts, metal panel systems, rain screens, canopies, overhead doors and skylights.  All of these items will impact how the studs are loaded and will influence design.  The professionals of record typically are not overly helpful when questioned on these items.  It is also common that the items as a whole are not being coordinated.  This cannot all fall on the cold-formed specialty engineer.

What are we going to do as an industry?  Anticipate and open discussion to collaboratively discuss this issue and devise a strategy to move forward.

Jamie attended Milwaukee School of Engineering and graduated in 2009 with a B.S. in Architectural Engineering and M.S. in Structural Engineering. She joined the Excel Engineering, Inc. Cold Formed Steel Department in 2010. She currently performs engineering duties on various project types with locations across the country, as well as serves as the group’s Mentor for new employees. Jamie also has a published Feature article in the February 2015 issue of Structure Magazine.
