    Although simplified static methods for seismic design are adequate for short, simple, and symmetric buildings, often structures fall outside one of these categories.  Buildings with re-entrant corners, floor plan irregularities, or multiple stories require a detailed dynamic calculation such as a response spectrum analysis (RSA).   

    On Wednesday, May 22nd, I will introduce you to an ASCE 7-16 response spectrum analysis in RFEM with a free 1-hour webinar available for 1 PDH credit.

    WASHINGTON, DC, February 21, 2019—The Steel Bridge Task Force of the Steel Market Development Institute (SMDI), a business unit of the American Iron and Steel Institute (AISI); the National Steel Bridge Alliance (NSBA); and the American Association of State and Highway Transportation Officials (AASHTO) T-14 Technical Committee for Structural Steel Design have named Ed Wasserman, senior engineer of bridge design and engieering at Modjeski and Masters, as the recipient of the 2019 Richard S. Fountain Award.

    Named for the founder of the Steel Bridge Task Force, the Richard S. Fountain Award recognizes leadership in steel bridge research and outstanding efforts to advance AASHTO specifications. Wasserman received the award at the meeting of the Steel Bridge Task Force on January 24, 2019 in Orlando, Florida. The award was presented by Ronnie Medlock of High Steel Structures, who is also chairman of the Steel Bridge Task Force Oversight Council; Tom Macioce of the Pennsylvania Department of Transportation, who is also chairman of the AASHTO T-14 Committee; and Chris Garrell of the NSBA. 

    “Throughout his career, Ed has made lasting contributions to the improvement of steel bridge design,” said Robert Wills, vice president of construction market development for the Steel Market Development Institute. “When he chaired the AASHTO T-14 Committee, Ed championed a multi-year research project that completely overhauled the AASHTO specifications to unify the design of straight and curved steel girders, resulting in more cost-effective steel bridge designs. He was always quick to engage the Tennessee Department of Transportation in the development and testing of new design strategies for construction innovations such as High-Performance Steels, also known as HPS.”

    Wills noted that the Tennessee Department of Transportation built the first HPS bridge in 1998.  High-Performance Steels were developed by the American Iron and Steel Institute; Carderock Division, Naval Surface Warfare Center; and the Federal Highway Administration. They are more cost-effective, higher in strength, lighter in weight, and have greater atmospheric resistance than conventional steels, along with enhanced fracture toughness. 

    Before joining Modjeski and Masters, Wasserman was director of the Structures Division at the Tennessee Department of Transportation. He served as chairman of the AASHTO T-14 Committee for 25 years and was also chairman of the AASHTO T-10 Technical Committee for Prestressed Concrete Design (later subsumed into the Technical Committee for Concrete Design). He has authored or co-authored 16 papers on various bridge design topics. One of his co-authored publications is “Integral Abutments for Steel Bridges,” which synthesized the state-of-the-art design and construction practice for integral abutments that was instrumental in extending the service life of steel bridges. Over the course of his career, the Structures Division he led received 34 design excellence awards. Among personal awards received are those from the Lincoln Arc Welding Foundation and the American Institute of Steel Construction.

    The Richard S. Fountain Award was established in 2001. Past recipients of the award include:

Has the 'Mass Timber Revolution' Come to the US South?

By Jeff Peters, PE, WoodWorks

If you follow architectural news, you know that wood building design is evolving beyond its traditional boundaries, with projects like the 8-story Carbon 12 in Portland, the 7-story T3 Minneapolis, and the new Design Building at UMass Amherst, one of the most advanced mass timber buildings in the country. It's been called a mass timber revolution, but are we seeing evidence of that in the US south?

The answer is yes, with one caveat: in the south, the trend seems broader. Designers here haven't traditionally used a lot wood for commercial and larger multi-family buildings—but that's changing as more people recognize the performance capabilities of wood systems.

I say this because I'm out there every day, providing technical support that makes it easier for architects and engineers to design wood buildings, and my colleagues across the country are doing the same. (WoodWorks provided support for all three of the buildings noted above.)

In this region, I'm seeing more designers leveraging the aesthetic of heavy timber for commercial buildings and the economy of wood framing to achieve quality mid-rise projects at less cost. For example:

Blaze Pizza – Lake Buena Vista
When I met an architect with Morris Architects, he expressed an interest in learning more about WoodWorks and wood design. I presented a lunch and learn to the firm, which started thinking about the potential of mass timber for a restaurant project. I connected them with a local mass timber design and construction specialist, and the result is this beautiful flagship location. Complete


Cortland Westshore – Tampa
Although allowed by code, officials were resistant to a Type III wood-frame building, fully sprinklered. To assist Baker Barrios Architects, I provided a letter outlining a code path that allowed for approval. The information was shared with other architects at the firm to help gain approval for their own projects. Under construction

Home Street Apartments – Jacksonville
I've been working with Fisher and Koppenhafer Architecture to support the design of a luxury wood-frame apartment building. Topics have included construction type, fire walls, and fire- and acoustic-rated assemblies. Under construction

There are signs that mass timber is also trending upward in the south. Hines, the developer of T3 Minneapolis, broke ground on T3 Atlanta earlier this year. Designers are also proving keen to learn about products and applications, as evidenced by their attendance at our mass timber-focused events. More tangible, perhaps, is the fact that a manufacturer recently announced that it will open a plant in Alabama to produce cross-laminated timber (CLT) from Southern pine.

If you're considering mass timber for a project, my contact information is below. I can bring your team up to speed on the design process, help resolve technical issues, point you to key resources, and introduce you to suppliers—all at no cost to you.

Are you Leveraging Our Resources?

Breaking Convention with Wood OfficesThe WoodWorks website offers a wealth of information for architects, engineers and others involved in the design of wood buildings. Highlights:

Case study – Breaking Convention with Wood Offices – Includes examples of different wood systems and discussion of issues such as construction type, heights and areas, grid, lateral systems, cost, and more

Solution paper –  Accommodating Shrinkage in Multi-Story Wood-Frame Structures – Describes procedures for estimating wood shrinkage and provides detailing options that minimize its effects

Ask an Expert – How is MEP accommodated in exposed mass timber buildings? – Look for a new Ask an Expert at the start of each month!

While we're on the topic of resources, don't forget to sign up for our next (free) webinar – Modular Construction: Tomorrow's Multi-Family Buildings at Today's Price – December 12 at 1 p.m. EDT.
