Connection Design: Tips, Tricks, and Lessons Learned

The first Night School course of 2019, Connection Design:  Tips, Tricks, and Lessons Learned, tackles everything you need to know about steel connection details.  Taught by five of our industry’s foremost experts, this course will provide instruction on the connection design process and the latest design methods.  There will be a special focus on delegated design – not just “how to design it.”  These eight sessions will cover what information to provide on construction documents and the complications that arise from insufficient information.  The course starts with an overview of delegated connection design, and then proceeds to go in depth on the most useful connection types.  The final session will be a rare opportunity to hear stories on lessons learned from the unmatched experience of our speakers.  This course will provide instant benefit to you and your practice, whatever role you have in connection design.

Sessions

Larry Muir, PE

This session will focus on the responsibilities, relationships and communication among the various parties involved in the delegated design process. It will discuss how delegated connection design is addressed in the AISC Code of Standard Practice. Ways in which proper communication between the engineers can be maintained to ensure the safety of the structure while also addressing concerns about contract management will also be presented. Finally some general tips for those wishing to perform delegated connection design will be provided.

Session 2: Delegating Connection Design

Clifford Schwinger, PE

The cost of connections is a significant percentage of the total cost of steel-framed structures. This webinar reviews how designers can efficiently delegate connection design in a manner that saves time, reduces RFI’s, reduces cost, and conforms with the requirements of the Code of Standard Practice. This session discusses the EOR’s responsibility regarding delegation of connection design as stipulated by the COSP and reviews how decisions made relative to framing configuration during design can substantially affect connection cost. Tips, guidelines, suggestions, and examples will be presented to provide designers of all levels of experience a better understanding on how to properly delegate connection design in a manner that will result in safer, more constructable, and more economical steel-framed building structures.

Session 3: Shear Connections

Patrick J. Fortney, PhD, PE, SE, P.Eng

Indisputably, beam end shear connections comprise the bulk of the total connections in a structural steel package. Connection designers have a plethora of options in regard to the type of shear connections to use. Magnitude of load, geometry, main member type, erection ease, shop schedule, and project specifications are just some of the considerations that impact the decision on the type of connection to use.

This presentation will present the information that a delegated connection designer will: (1) need to make an informed decision on connection type and design, and; (2) need to provide to the EoR to facilitate the review process.

Session 4: Moment Connections

Patrick J. Fortney, PhD, PE, SE, P.Eng

Bolted or welded; should the EoR and delegated connection designer collaborate on this decision? Gravity or Lateral; does it make a difference in the design of the connections? Beam axial load equals transfer force; should it be obvious to the connection designer where, and for what magnitude, transfer forces are required in design? 

This presentation will present the information that a delegated connection designer will: (1) need to in order to make an informed decision on connection type and design, and; (2) need to provide to the EoR to facilitate the review process.

Session 5: Vertical Bracing Connections

Carol Drucker, PE, SE

Don’t waste time showing too much information that isn’t used or that can unnecessarily complicate your design. This session will include tips for successful delegated vertical bracing design and what information should be included on drawings, which will help you limit RFIs and resubmittals.

Session 6: The Chevron Effect

William A. Thornton, PhD, PE, NAE

V- and inverted V-type braced frames are common brace configurations. Generally referred to as chevron systems, the configuration requires braces to frame to braced frame beams away from the beam-column joint. Typically, the effects of the brace forces on the beam and the impact on the beam end connections are overlooked. Standard practice in connection design is to assume that the joint is isolated from the frame, and to assume that the impact of the brace forces on the beam is isolated to the connection region. If the algebraic sum of the vertical components of the braces forces is zero, this assumption is generally valid. However, connection designers rarely deal with a zero summation of vertical force components. When the summation of the vertical components of the brace forces is non-zero, the location of the work point along the length of the beam and the span of the beam can significantly impact how beam shear and moment is distributed along the span of the beam, especially in the region of the connection. This is referred to as the chevron effect.

 

This webinar presents discussion on how brace forces are distributed through a chevron connection, and explores the impact of the brace forces on the design of the beam . Formulas are presented which allow the designer to determine if the Chevron Effect will impact the beam design.

Session 7: Seismic Connections

Patrick J. Fortney, PhD, PE, SE, P.Eng

From mechanistic design forces to critical welds to protected zones to prequalified connections to exceptions, the SEoR and delegated connection designer need to be in phase with one another before connection design begins. Documented communication on all aspects of the project between the SEoR, fabricator, erector, and inspector is paramount in order to avoid unwelcome shaking of project schedule and budget.   

This presentation will present the information that a delegated connection designer will: (1) need to in order to make an informed decision on connection type and design, and; (2) need to provide to the EoR, fabricator, erector, and inspector to facilitate the review and quality processes.

Session 8: Lessons Learned

Patrick J. Fortney, PhD, PE, SE, P.Eng; Larry Muir, PE; William A. Thornton, PhD, PE, NAE

In this session, the speakers will share stories, from their respective careers, that have shaped their views on how delegated connection design can be successfully implemented on structural steel projects.
