Massive amounts of timber. Tons of structural steel. Envisioned as the centerpiece of a revitalized fairgrounds complex in Washington County, Oregon, the Wingspan Conference And Event Center due to open in summer 2020 includes a high-tech 39,000-square-foot expo hall with 30ʹ ceilings, a rooftop solar array, a 13,000-square-foot conference center to accommodate trade shows, corporate meetings, and seminars, and a materials list of building products to rival any commercial or civic construction project.
Before starting my fellowship, a year seemed like a very long time to be away from my day-to-day life, my clients, and my comfort zone. I started with many questions about how I could support the Build Change team to make the biggest possible impact with this fellowship. Once I started, however, I found more than a great team; I found a family. I would like to start this blog by praising the support of every member of the teams that I worked with, including the Build Change headquarters staff, as well as the staffs of the programs in Colombia and the Philippines.
The Simpson Strong-Tie® Composite Strengthening Systems™ was used to restore and strengthen 6 distressed cast-in-place concrete grain silos with a combination of carbon and glass FRP, meeting a tight timeline and budget.
In this post, we follow up on our July webinar, Safer, Stronger Decks: Ledger Connections for Wood and Masonry, by answering some of the interesting questions raised by attendees.
During the webinar we discussed code-compliant ledger connection
options for both wood and masonry construction. In case you weren’t able to join our discussion, you can watch the on-demand webinar and earn PDH and CEU credits here.
Design criteria for cracked-concrete masonry units are finally available for adhesive anchors.
It has been over 15 years since cracked concrete changed the way anchorage to concrete was qualified and designed. The ICC International Building Code (IBC) 2003 referenced American Concrete Institute (ACI) 318-02 Appendix D as a design provision for both cast-in-place and post-installed anchors into concrete. Appendix D was the first introduction of cracked concrete to designers. These design provisions required mechanical anchors to be qualified per ACI 355.2, which mandated testing of anchors in cracks. The Masonry Society (TMS) 405 has not addressed cracks in concrete masonry units since the code’s introduction to concrete in 2003. The Concrete and Masonry Anchor Manufacturers Association (CAMA) has taken on the task of introducing cracked masonry unit testing, qualification and design by updating Acceptance Criteria AC58. These criteria were developed to address the testing and qualification of adhesive anchors in grouted, hollow, and partially grouted concrete masonry units, as well as in brick masonry units.
The year is moving fast; my time supporting the team in Colombia is over. My time is now fully committed to the program in the Philippines.
During my initial trip, I had the chance to visit some of the communities where Build Change has been working and become familiar with the existing tools used in these communities. Also, I was introduced to the crucial role that microfinance institutions (MFIs) play in Build Change’s strategy to retrofit vulnerable houses in the Philippines.
In 2009, Simpson Strong-Tie participated in an unprecedented research event to highlight the importance of earthquake-resistant wood construction.
The event, the world’s largest earthquake test, was a collaborative Network for Earthquake Engineering Simulation project. It teamed academics, engineers, and industry researchers from around the world to subject a structure to what engineers refer to as the “maximum considered event” (MCE), a large, rare earthquake projected to occur, on average, approximately every 2500 years.
Our “Quik” line of tools now has jobsite efficiency covered from subfloor to drywall to rafters. The Quik Stik overhead assembly fastening system is our most recent innovation in a line of fastening systems that also includes the Quik Drive® PRO250G3 subfloor system and the Quik Drive PRODW drywall system. It provides contractors with a versatile solution that makes fastening rafter and truss connections faster and easier than ever. Here are five ways the Quik Stik raises the bar on overhead fastening.
The Simpson Strong-Tie® FX-70® structural pile repair and protection system was used to restore and protect 267 seriously corroded steel pileswith a corrosion-resistant protective shell.
