With the recent introduction of our new LSSR rafter hangers for 2x lumber, we thought we’d provide some background on how these new hangers were developed and why.

How a Top US Homebuilder Turbocharged Market Growth and Managed the Job Start Process with the Scalable LotSpec Solution from Simpson Strong-Tie
As one of the top 10 private homebuilders in the US (and one of the top 25 overall), Gehan Homes has explored its fair share of technologies promising efficiency and productivity gains. When it came to pulling home designs, plans, elevations, and options into full job start packets (JSPs), the Texas-based homebuilder managed to generate about 400 JSPs per year before the productivity cost of eight hours each began to limit growth.
Yield-Link® Moment Connections in the Great White North
Resiliency is a term which is becoming more commonplace within the field of structural engineering, not just in North America but worldwide. As part of a nation that prides itself on being progressive, engineers in seismic zones of Canada are already exploring innovative solutions that may help create economic structures with resiliency in mind. But what do we mean by resiliency?
In the fields of engineering and construction, resiliency is the ability of a structure to absorb or avoid damage without suffering complete failure. Structural resiliency is the ability of a building or structure to remain sufficiently sound and intact following a shock event as to allow rapid resumption of normal use.
Case Study: Gruening Middle School’s Seismic Damage Repair Solution
It can be a challenge to repair an earthquake-damaged structure.
During the 7.1-magnitude 2018 Anchorage earthquake, Gruening Middle School in Eagle River sustained more damage than any other school in the Anchorage School District. Review of the school showed the existing masonry walls suffered damage and separation from the roof. During the retrofit design, the Reid Middleton structural engineering team (Anchorage) determined the masonry walls weren’t adequately reinforced to meet current code requirements. They were seeking an easy-to-install strengthening solution that wouldn’t add significant weight to the building.
Building Safe and Strong with Flood-Resistant Construction Workshops
Flooding is one of the few natural disasters that occur commonly throughout all regions of North America. The causes of floods can differ depending on the region, but the impact is nearly always the same. Recent floods have caused billions of dollars in damage annually to structures near the coast as well as inland.

NOVA airs episode featuring Strong Frame® Special Moment Frame Testing for NEES-Soft
NOVA, the highest rated science series on television, recently aired a segment on the Colorado State University-led NEES-Soft project that tested Simpson Strong-Tie® Strong Frame® special moment frames as a seismic retrofit solution for soft-story buildings. Simpson Strong-Tie and our special moment frame were prominently featured in the clip. You can watch the entire “Making Stuff Safer” episode on PBS here.
Upcoming Steel Deck Institute Webinars: 10/23 and 11/13
Steel Deck Institute (SDI) is hosting a “Designing With Steel Roof Deck” webinar on October 23 and November 13 at 11 a.m. EST. The webinar is intended to expand participants’ knowledge of steel roof deck by introducing them to the benefits, manufacturing processes, shapes, properties, and finishes of this product. The basis of the presentation is SDI’s new Roof Deck Design Manual, which will be provided to participants. Various roof deck design considerations will be explored as well as an overall coverage of fasteners and industry construction practices.
CANAM/United Steel Deck and Vulcraft will be presenting. Simpson Strong-Tie will be moderating the webinar and providing two PDHs (0.2 CEUs) for participants. Click here to sign up for one of the webinars.
