How High Can You Go? Exploring the Limits of 8 inch Concrete Masonry

This presentation will explore how the selection of materials, design methodology, and constructability influence the maximum height that can be achieved with an eight inch concrete masonry wall. Along the way, we will answer questions such as:

  • ·     What strength of masonry can be specified?
  • ·      How much reinforcing is too much?
  • ·      Does allowable stress design or strength design allow the design of taller walls?
  • ·      How much deflection can we allow?

    A Structural Re-Evaluation of the Collapse of WTC-7

    The sudden collapse of World Trade Center Building 7 on September 11, 2001 was an unprecedented failure of a high-rise steel framed building.  The National Institute of Standards and Technology (NIST) issued a report on the event seven years later, concluding that normal office fires caused the collapse. Numerous questions have arisen in the years since then regarding the conclusion of the NIST report.  In 2016, Architects and Engineers for 9/11 Truth hired the University of Alaska Fairbanks (UAF) to study all available evidence regarding the collapse and render an opinion on the validity of the NIST conclusion.  Professor Leroy Hulsey and two of his graduate students worked for four years on the report utilizing state-of-the-art methodology to examine the evidence.  A draft of the UAF report was issued in September, 2019 and was subjected to peer and public review for six months.  The final revised report was issued in late March, 2020 and at present is in the process of being submitted to several peer-reviewed journals for publication.

    The UAF report, “A Structural RE-Evaluation of the Collapse of WTC 7“, disagrees with the NIST report and concludes that the failure of WTC 7 was not caused by random fires in the building leading to a progressive collapse.  Instead, the UAF report concludes that the failure was a global collapse caused by the sudden removal of all the core columns in the building over eight stories, followed a split second later by the collapse of all the perimeter columns.

    J. Leroy Hulsey, Ph.D., P.E. earned his Bachelor's Degree in Civil Engineering from Missouri School of Mines and Metallurgy, his Master's Degree in Civil Engineering and his Ph.D. in Structural Engineering from University of Missouri at Rolla.  He has held his P.E. registration in North Carolina, Alaska, Alabama, Illinois and Missouri and his S.E. in Illinois and Alaska.  Over a 40-year period, the author has investigated, designed, or researched hundreds of small, medium, and long span bridges.  Between 1964 to present, Dr. Hulsey has designed and investigated many steel, concrete, and masonry low-rise buildings in the mid-west and eastern United States. Dr.  Hulsey also has extensive consulting and research experience with advanced composite materials. Dr. Hulsey has been responsible for failure investigations for structures in the mid-west, East Coast and Alaska.  This sometimes means installing instrumentation and testing a structure for a given condition.  Dr. Hulsey has extensive instrumentation experience.  This experience is often used to explain the behavior of an existing structure.  Examples, includes developing design methods for unusual structures such as water slides, the response of an automobile during a crash, and developing methods to evaluate the response of buildings to vibrating equipment in manufacturing plants.  Dr. Hulsey has also assisted engineers in evaluating the framing systems for assembly areas such as the Dean dome.  Dr. Hulsey is also a retired and Professor Emeritus at the University of Alaska Fairbanks after being a professor of Civil and Structural Engineering for over 30 years.


      SpeedCore – Composite Plate Shear Walls – Concrete-Filled

      SpeedCore2 is a non-proprietary system of concrete-filled composite plate shear walls (CF-CPSW).  The system replaces reinforced concrete core construction in multi-story buildings with the advantage of construction speed standing out as the most significant project benefit. The steel plate composite wall system leverages the stiffness of concrete and the speed and accuracy of steel for a superior lateral system.

      The history of composite construction is briefly reviewed with an emphasis on the use of the composite wall system in nuclear facilities.  The innovative shift from industrial to commercial construction will be detailed with a specific discussion of the Rainier Square Tower project designed by Magnusson Klemencic Associates. Basic design principles of the SpeedCore system used for Rainier Square are discussed with reference to the design resources currently available.  Research on the SpeedCore system investigating structural and fire protection optimization are shared within the context of the future of the system and its innovative impact on the design and construction industries.

The referenced standards for design loads, masonry, structural steel, wood, and cold-formed steel have all been updated from the 2015 to the 2018 IBC. The presentation then focuses on the major changes from ASCE 7-10 to ASCE 7-16, which are also the major structural changes from the 2015 to the 2018 IBC. Very substantial changes in seismic design, wind design, design live loads, and design load combinations are reviewed. The seminar ends with a brief look into the near term future.

      Three Decades of Innovation in Applications of FRP

      By now, most civil engineers are familiar with the original concept of repair and strengthening of structures using Fiber Reinforced Polymer (FRP) products that was proposed by the speaker in the late 1980s.  In that technique known as “wet layup”, fabrics of glass or carbon are saturated with epoxy and they are bonded to the surface of the structure; by the next day, the materials become 2-3 times stronger than steel.  This presentation starts with a brief overview of that technology and how FRP solutions have been used in Arizona to solve construction errors, and repair or strengthen deteriorated structures. Case studies cover  a wide range of applications, including residential buildings, hospitals, mines, and a recent ADOT/SRP project where this technology saved these agencies millions in repair costs.

      The second half of the presentation will focus on several new products developed by the presenter that facilitate repair solutions where the original wet layup system could not be used.  A review of these developments and some of the testing by government agencies such as Texas DOT and the Army Corps of Engineers will be presented.  Case studies where these products have been used worldwide to repair ports, piers, bridges, seawalls, pipes and culverts resulting in savings in repair time and cost will be presented.

      Mo Ehsani, Ph.D, P.E., S.E. received B.S., M.S., and Ph.D. degrees from the University of Michigan before joining the department of Civil Engineering at the University of Arizona in 1982.  He pioneered the field of repair and retrofit of civil structures with Fiber Reinforced Polymer (FRP) materials in the 1980s and has published these findings in numerous professional journals such as ACI, ASCE, Earthquake Spectra, etc.  Dr. Ehsani is a Fellow and Life Member of the American Society of Civil Engineers and the American Concrete Institute (FACI).  He has served as President of the SEAoA and is a registered professional engineer in eighteen states. Professor Ehsani has been featured on major media such as CNN, National Public Radio, the History Channel, and Engineering News Record for his expertise on strengthening of structures, particularly related to earthquakes, terrorist attacks and other potential structural disasters.  He has invented twenty FRP systems and received the 2014 Arizona Technology Leader of The Year Award.

      In 2010, Dr. Ehsani left the University of Arizona as a Professor Emeritus to devote his full attention to QuakeWrap, Inc., a company he had founded in 1994 that specializes in repair and retrofit of structures with FRP.  The company offers turnkey design/build solutions to its international clients.  Numerous award-winning projects and creative solutions/products developed to address the clients’ needs attest to the unique capabilities of this company. In September 2014, QuakeWrap was inducted into the U.S. Congressional Records as “…a small business that has grown by being a leader in state-of-the-art technology and by embracing exporting as key to its growth strategy.”
