The Chevron Effect - Not an Isolated Problem
William A. Thornton Ph.D, PE, NAE
V- and inverted V-type braced frames are common brace configurations. Sometimes 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 assume that the impact of the brace forces on the beam is isolated only over 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. This is referred to as the chevron effect.

This presentation presents discussion on how brace forces are distributed through a chevron connection, and also explores the impact of the brace forces on the beam and the beam end connections. A rule of thumb for accounting for the chevron effect during member size selection is also presented.

Advancing the Practice of Structural Engineering:
NCSEA Call for Abstracts for 2016 Structural Summit
DUE:  February 22, 2016
The 2016 NCSEA Structural Summit will be held at Disney's Contemporary Resort from September 14-17. It will feature two full days of both technical and non-technical tracks designed to advance the practice of structural engineering.  Presentations will deliver pertinent and useful information that attendees can apply right away in their structural engineering practices.

NCSEA has issued a call for presentation abstracts for this event, with a DUE DATE of February 22, 2016.   Desirable presentation abstracts are those that provide the most value to the practicing engineer, such as best-design practices, project management, new codes and standards, office management, recent projects, advanced analysis techniques and similar topics of interest to practicing engineers.


NCSEA leaders encourage all members to take advantage of this opportunity to use their professional skills and give back to the profession. Everyone has a unique way of approaching problems, and how you resolved a challenge in your practice may be just what another engineer needs. When we share our knowledge, it is good for the profession overall.    
NCSEA Note:  Engineers from all levels of knowledge and experience will attend the Summit, so topics should include anything from the most technical topic to ones that can help streamline office efficiency. Requests for specific topics are also welcomed.  Our diverse planning committee consists of engineers from across the country that practice on a wide range of projects, and can speak to particular topics. 

Young Member Spotlight:
Samantha J. Kendrick, ME Candidate

Samantha J. Kendrick, EIT, ME Candidate, is currently completing the final semester of her Master's degree in Structural Engineering at Tufts University.  A native of Long Island, NY, Samantha joined the SEAMASS Young Members Group (YMG) in 2014, and currently serves on the Executive Board in the Events Committee. She has answered the questions below, so we may get to know her better.  Thank you, Samantha, for your contributions to SEAMASS and the Structural Engineering profession!

Q:  Why did you join SEAMASS?
  I originally joined SEAMASS because I felt that it is of the utmost importance to surround yourself with like-minded individuals. Mentorship is the key to a thriving career and I knew that by joining SEAMASS, I would be immersed into an environment that was conducive to the success of young and aspiring structural engineers like myself.  I will never forget the first time I attended a SEAMASS meeting, on Thursday, November 13th at the Northeastern University Kostas Research Center.  Although I was very nervous about attending the meeting as a young graduate student and had to travel over an hour and a half for the 8:00am meeting, it was one of the best decisions I could have ever made.
Q:  What are your goals as an engineer?
A:  My goals are to obtain my Professional Engineering License along with my Structural Engineering license in the efforts of ultimately mastering the art of structural engineering while increasing my level of intuitiveness and technical proficiency within structural analysis and design.  My desire is to continually strive to not just make structural engineering a job, but an innate and natural technical skill set. In doing so, I plan to integrate architecture and structural engineering to work with new design and high rise structures.  

Q:  Please describe a project that you're involved with.
A:  A current project that I am working is my final project for the Masters course at Tufts University titled Experimental Methods in Structure and Materials.  This course incorporates structural analysis and design with experimental instrumentation.  For my project specifically, I designed two (2) reinforced cantilever shear walls with both shear and flexural reinforcement for laboratory small scale testing.  All materials for the project were designed and created in the lab including the sizing and cutting of reinforcement and the assembly of the wooden framework which will encase the concrete walls.  The concrete, which is a synthetic lightweight concrete aggregate, was  poured and cast on Thursday, December 3rd, and I am now in the process of testing and the associated analysis.

Q:  How do you spend your free time?
A:  I remain heavily involved in leadership activities and am currently serving as the National Leadership Institute (NLI) Director of Leadership Development for the National Society of Black Engineers (NSBE); however, in my free time I love reading, working out and snowboarding when I can!  I believe that the best thing in life is to have balance.  With that said, it is important that we create free time for ourselves, no matter how busy we may become.
