01. Fluid harmonic damper

TTWiiN, the technology accelerator of Thornton Tomasetti, introduced Hummingbird Kinetics, a solution for tuned mass damping in tall and supertall buildings as an alternative to slosh tanks and pendulum dampers. As cities increase in density and more tall buildings are built, there is a need for a better solution to the challenge of wind-induced motion in large buildings. According to the company, the Hummingbird solution is a patented and competitively priced fluid harmonic damper (FHD) that can be distributed throughout a building, improving efficiency and giving more leasable space back to the building owner.

02. Sewer infrastructure repair

Quadex, LLC, a Vortex Company, said that its GeoKrete Geopolymer meets the most demanding European test standard for corrosion resistance, WXX4, as defined by DIN 19573: Mortar for Construction and Rehabilitation of Drains and Sewers Outside Buildings. To comply with DIN 19573, in all testing phases, GeoKrete possessed a relative residual compressive strength greater than 55 percent for pH0, and greater than 75 percent for pH1. GeoKrete is used for repair and rehabilitation of manholes, large-diameter pipes, and other sewer infrastructure requiring structural and corrosion protection.

03. Sewer system sensors

The San Antonio Water System (SAWS) is in the process of deploying 200 SmartCover Systems real-time remote sensors to keep a high-tech eye on troubled pipeline segments citywide. SmartCover Systems provides sewer collection systems asset management solutions through Real-Time Condition Assessment. According to the company, utilizing a wide array of applications designed to capture remote data, software and analytics enable informed, actionable decisions resulting in prioritized capital projects. In 2014 alone, the SAWS SmartCover system prevented more than 500 potential sewer system overflows at locations with a high risk due to structural condition, grease, debris, or roots.

04. Rod-to-steel-beam connector

ProductIllustration

Simpson Strong-Tie’s new Strong-Rod Systems rod-to-steel-beam connector (ATS-SBC) forms part of a continuous-rod solution that helps wood-frame structures resist shearwall-overturning forces and uplift forces resulting from seismic activity or wind events. The rod-to-steel-beam connector has been redesigned to reduce the overall number of rod system components. The new ATS-SBC replaces the older field-assembled half-cage system with a complete part featuring a rod already affixed to the bearing plate. It also features a weldable plate for attachment to steel beams in the field. The rod-to-steel-beam connector is available in six rod diameters ranging from 5/8 inch to 1-1/2 inch, all 12 inches in height.

05. High-solids primer

Sherwin-Williams Protective & Marine Coatings’ Zinc Clad 4100 is a new high-solids coating featuring recoat times as short as 30 minutes. Designed for use over properly prepared blasted steel, the organic zinc-rich primer provides cathodic protection to reduce corrosion potential in the event of the steel substrate being exposed due to coating damage. Zinc Clad 4100 meets Class B requirements for slip coefficient and creep resistance as defined by the Research Council on Structural Connections for use in slip-critical bolted connections in all U.S. states. It also meets the performance requirements of NEPCOAT List B for use on highway bridge steel in the Northeast U.S.

06. Concrete admixture

New Technology Solutions, LLC developed patent-pending CoolCure, which the company said significantly reduces/eliminates the heat of hydration and increases compressive strength and working/placement time of concrete. Increases in strength have been realized from 40 percent to 100 percent, the company said, and heat of hydration is reduced by minimizing generation of calcium hydroxide byproduct. CoolCure is ideal for large mass pours and can be implemented in existing concrete mixing facilities and trucks. CoolCure also reduces the potential for delayed alkali-silica reaction, according to the company.

07. Geosynthetic support pad

HUESKER’s Fortrac Heavy Load geosynthetic support pad for storing extra-heavy units, (e.g., monopiles for offshore wind turbines or ship components) has load capacities of 800 tons and greater. Fortrac Heavy Load, which can be supplied in different heights and widths, features a combination of two high-tensile geosynthetic products with local soils or slags as the fill material. It is deliverable in kit form for onsite assembly. Other benefits include its transportability by heavy-duty forklift and the possibility of future recycling for support pads that are no longer required. Other options include the possibility of installing drainage units for hydraulic filling and covers for protection against rain.

08. Cold-formed steel e-book

BuildSteel, a partnership of steel and construction industry organizations, released Cold-Formed Steel Trusses: Design, Performance, and Advantages, a complimentary e-book to help building owners, architects, contractors, and engineers better understand how cold-formed steel (CFS) truss systems can help them in their next project. Within the e-book, building professionals will learn why multi-family and mid-rise projects benefit from CFS trusses; how CFS trusses help solve complex challenges and support design flexibility; and how CFS truss systems deliver on performance and life cycle savings. The e-book can be downloaded at www.buildsteel.org/ebook-cold-formed-steel-trusses-design-performance-and-advantages.
