01. Interlocking concrete pavement design

The Structural Design of Interlocking Concrete Pavement Committee of the Standards Council of the Transportation & Development Institute of the American Society of Civil Engineers (cosponsored by the Interlocking Concrete Pavement Institute) published Structural Design of Interlocking Concrete Pavement for Municipal Streets and Roadways, Standard ASCE/T&DI/ICPI 58-16. The standard establishes guidelines for developing appropriate pavement structures for various traffic and subgrade conditions. This standard applies to paved areas subject to applicable permitted axle loads and carrying up to 10 million 80-kN equivalent single-axle loads. The standard provides preparatory information for design, key design elements, design tables for pavement equivalent structural design, construction considerations, applicable standards, definitions, and best practices.

02. Moment-resisting post base

Simpson Strong-Tie’s MPBZ moment post base provides moment resistance for wooden columns or posts, reducing the need for knee bracing, providing greater design possibilities for outdoor structures. According to the company, the MPBZ is ideal for freestanding structures such as carports, fences, and decks. It features an overlapping sleeve design, which encapsulates the post, keeping it from rotating around its base when lateral loads are applied from above. The MPBZ’s ability to withstand lateral loads greatly reduces or eliminates the need for diagonal knee bracing to provide more versatility in creating open-air structures with unobstructed views.

03. Dissipative wall anchor

Cintec International developed a new type of dissipative wall anchor for use with Cintec’s wall anchor system that it said solves issues of how to protect heritage buildings in some of the most earthquake-prone parts of the world. The Cintec dissipative anchor consists of a set of stainless steel plates to which four bolts apply pressure, creating friction to an adjustable degree. Built-in stops restrict the sliding motion and connectors link to Cintec’s standard anchor rods. The anchor allows a controlled and repairable drift for the walls, managing the amount of seismic energy fed into the structure and therefore minimizing damage to the building.

04. 2017 Manual of Concrete Practice

The American Concrete Institute (ACI) released the printed and digital editions of its 2017 Manual of Concrete Practice. Containing more than 250 documents, the ACI Manual of Concrete Practice is the most comprehensive and largest single source of concrete practice information available in one set. The manual contains all of the ACI documents needed to answer any questions about code requirements, specifications, tolerances, concrete proportions, construction methods, evaluation of test results, and many more topics. It also includes the reorganized version of ACI 318, Building Code Requirements for Structural Concrete and Commentary.

05. Precast concrete foundations

Oldcastle Precast, Inc. acquired the assets of Cell Blocks, Inc., a provider of patented precast concrete foundations for cellular towers and other utility equipment. Cell Blocks post-tensioned foundation systems have been used by all major U.S wireless carriers. The modular systems are configured to meet the requirements of each site and typically requires only one day for installation. The acquisition is expected to strengthen Oldcastle Precast’s position in the telecommunication market across the United States.

06. Wood building materials

According to reThink Wood, wood building solutions are an ideal option for U.S. schools to meet budget and safety requirements. For educational and institutional building construction, the organization said that wood building solutions typically cost less than alternatives — the average elementary and middle schools could realize cost savings of nearly 22 percent — and wood construction is fast, particularly with prefabrication and panelized products such as cross-laminated timber and mass timber technologies. As a renewable resource, wood offers a lower carbon footprint compared with other common building materials and improved energy efficiency performance due to its inherent insulating qualities.

07. Construction products website

W. R. Meadows launched a new website implementing changes such as the basic feel and navigation. The website was redesigned to give it a more contemporary feel, including a more immersive front page, easier navigation to product information, and an enhanced layout, the company said. A key improvement of the website is its enhanced mobile-friendly features. The site automatically adjusts based on the width of the browser or size of mobile device. Content includes access to product data sheets, safety data sheets, project profiles, and more. Product categories include building envelope, concrete restoration, joint sealants, and more.
