Coordinating Cold-Formed Steel Framing With Metal Buildings Jeff Klaiman, P.E., Adtek Engineering, Inc. Monday, May 19, 2014 | 3:30 p.m. – 4:30 p.m.

Metal buildings and cold-formed steel (CFS) framing are related in

many ways, but have some significant differences in design and

detailing. These differences can cause confusion and create problems

in newer projects that marry the two framing systems into a single

project, making use of the benefits and efficiencies of both systems. Originally

developed for large-span, simple open structures such as warehouses and

manufacturing facilities, metal buildings are increasingly being used for the

base structure of more complicated structures, such as schools and churches.

These buildings use CFS framing for both interior and exterior veneer and

finish support to accommodate the more intricate architectural requirements of

these less commercial structures. This seminar will provide guidance for CFS

framing design and detailing, along with actual project examples and details, of

some of the many items that must be considered in coordinating the use of CFS

framing with metal buildings.

Jeff Klaiman has over 20 years of experience in the construction industry that

includes building maintenance and engineering, on-site engineering for a

concrete contractor, Manager of Technical Services and Versa-Truss Product

Manager for Dale/Incor (national manufacturer of cold-formed steel framing

products and systems), participation in multiple committees of the American

Tuesday, May 20, 2014 | 10:30 a.m. – 11:30 a.m.

Many states are now adopting the 2012 International Building

Code (IBC), which references the new ASCE 7-10. ASCE 7-10 has

adopted a different format for determining the wind speed for

structures and has changed the loading equations for how to apply this load.

The code has adopted new wind speed maps which vary depending on the risk

category of the structure. It has also separated and expanded the MWFRS and

the Component and Cladding chapters in hopes of clarifying these methods for

analysis. This presentation will give a brief overview of these changes, how to

implement them and the effects on design, plus allow time for engineers that

have been using the code to discuss areas of concern or have questions

answered by fellow practicing engineers.

Jennifer Zabik, P.E., S.E. is President of Zabik-Turner Engineering. She has

been practicing structural engineering for nearly 10 years in the state of Florida

Tuesday, May 20, 2014 | 10:30 a.m. – 11:30 a.m.

This is an open discussion focused on several cold-formed steel

design issues that are not fully addressed by codes, standards or

industry guidance and, therefore, require some engineering judgment.

Designers routinely encounter such challenges, but rarely have the opportunity

to discuss solutions with their peers. A panel of experienced cold-formed steel

design professionals will lead the discussion and share their insights and

practices. Attendees will then be invited to share their experiences.

Design challenges for discussion:

Wall studs bearing on concrete

Design of built-up sections

Amount of gravity load applied to a shear wall boundary stud

Floor vibration for cold-formed steel floor systems

As time allows, the moderator will facilitate an open forum to identify

additional topics for discussion at this or a future CFS Design Forum.

Mid-Rise Bearing-Wall-to-Floor Interface: Solving the Load Transfer Dilemma Don Allen, P.E., LEED AP, SECB, DSi Engineering

Tuesday, May 20, 2014 | 1:30 p.m. – 2:30 p.m. When building traditional cold-formed steel (CFS) systems “by the

code”, alignment is required between joists and studs. This has caused

logistical, load path, design, and construction difficulties on many multi-story

structures. In this presentation, Allen draws on his years of experience and

research into CFS to show details, designs, and photos of what has worked and

what may be problematic. From load distribution members to open web joists

to ledger framing to shear walls, this presentation will show some of the new

(and old) ways that designers are getting around alignment framing, while still

building cost-effective structures that meet structural, fire, and acoustic

requirements. Case studies and sample problems will be included with

presentation materials.

Don Allen, P.E., LEED AP, SECB, is currently Senior Engineer at DSi

Engineering, an Atlanta-based structural firm that specializes in mid-rise CFS

AISI S310 Diaphragm Standard – What’s New for Steel Diaphragms Thomas Sputo, Ph.D., P.E., S.E., SECB, Steel Deck Institute

Tuesday, May 20, 2014 | 2:45 p.m. – 3:45 p.m.

The AISI S310 - North American Standard for the Design of Profiled Steel Diaphragm

Panels is the first consensus standard for the design of steel deck diaphragms.

This Standard is based on the methodology developed by Dr. Larry Luttrell

that forms the basis of the Steel Deck Institute Diaphragm Design Manual. The

AISI Standard incorporates the analysis methodology while also using fastener

strengths from the AISI S100 Standard. New to this method are explicit

methods of using steel deck diaphragms on thinner supporting structures, such

as cold-formed steel trusses. Also included are test-based methods for

determining the strength of steel panel diaphragms. You will leave this session

with an overview of the Standard and how to apply it to steel panel

diaphragms.

Proper Loading Specifications for Cold-Formed Steel Trusses Bill Babich, P.E., TrusSteel Sowri Rajan,P.E., TrusSteel

Tuesday, May 20, 2014 | 2:45 p.m. – 3:45 p.m.

Prefabricated cold-formed steel (CFS) roof and floor trusses are utilized on

various types of buildings, such as banks, assisted living facilities, hotels,

educational institutions, government projects, military facilities, industrial

buildings, churches, gymnasiums, etc. Their use varies widely, and with that,

the loads that the trusses need to resist vary greatly and come in many different

forms. Trusses resist vertical loads as well as lateral loads whose origins

determine the way the trusses are to be loaded. Some examples of the types of

loads that trusses resist are live, dead, wind, seismic, blast,

gymnasium goal posts, drag loads, steeples, safety tie points,

sprinkler pipes, signs, etc. This presentation will go through the

various types of loads that CFS trusses are required to resist and

demonstrate how to properly specify their use and utilization.

Bill Babich, P.E., is the Director of Engineering for TrusSteel.

TrusSteel is a provider of CFS truss engineering and technology utilizing the

proprietary TrusSteel system. He has been involved in the prefabricated truss

industry for the last 28 years and specifically with the CFS industry since 1997.

Mechanical Bridging and Bridging Anchorage of Axially Loaded Cold-Formed Steel Studs Nabil A. Rahman, Ph.D., P.E., The Steel Network, Inc.

Tuesday, May 20, 2014 | 4:00 p.m. – 5:00 p.m. Cold-formed steel (CFS) studs provide a cost-effective and

extremely efficient structural solution for the typical mid-rise building. In

recent decades, CFS design has evolved tremendously as the behavior and

design constraints of the material continue to be better defined through

comprehensive research and testing. As our understanding of the behavior of

CFS studs continues to evolve, the height of a typical mid-rise CFS structure

continues to rise, making it critical to the integrity of the structure that these

heavily loaded studs be properly braced. This presentation provides an

understanding of the design requirements and methods to laterally brace

(bridge) axially loaded cold-formed steel studs against flexural buckling,

torsional buckling, and torsional-flexural buckling. The design requirements

for the bridging components of axially loaded cold-formed steel studs are

described in the specifications published by AISI. The 2009 International

Building Code (2009 IBC) references the 2007 edition of the AISI North American

Specification for the Design of Cold-Formed Steel Structural Members (AISI S100-07).

The 2012 IBC references AISI S100-2007 with the 2010 Supplement (AISI S100-

07-S2-10). The bridging methods described represent a mechanical bracing

design consistent with an “all-steel design” approach. A “sheathing-braced

design” approach may also be used, but it is beyond the scope of this

presentation.

Nabil A. Rahman, Ph.D., P.E., is the Director of Engineering and R&D for The

Steel Network, Inc. in Durham, NC, and a past chairman of the Cold-Formed

Steel Engineers Institute (CFSEI). Dr. Rahman has vast experience in CFS

product development and design software development, as well as the analysis

and protection of CFS structures against extreme loads (progressive collapse,

blast and impact). He has given numerous continuing education seminars on

the design of cold formed steel framing systems to engineering groups. He has

participated in several vulnerability, blast and progressive collapse assessments

of commercial and military buildings. Dr. Rahman serves as a member of the

AISI Committee on Specifications and Committee on Framing Standards. He is

a member of the ASCE Disproportionate Collapse Technical Committee and

Serviceability of Open Web Composite Joists on Cold-Formed Steel Wall Bearing Systems Ric Anderson, P.E., Nucor Vulcraft Tuesday, May 20, 2014 | 4:00 p.m. – 5:00 p.m.

Although composite steel open web floor systems are very

cost-effective relative to other floor systems, many engineers

have not been designing them in CFS wall-bearing projects.

This presentation will discuss the benefits of composite steel joist systems, and
