- Use of galvanized box nails may result in shear walls with a shear capacity significantly below the nominal unit shear capacities given in SDPWS.
- Thus, the majority of WSP shear walls have a shear capacity with a high degree of design value variability. This may have unintended consequences that are unknown and unappreciated by the professional engineering and/or building design community.
- Once SBCA and SBCRI were certain their testing and engineering analysis was consistent and repeatable, they were persistent in bringing all WSP shear wall performance issues to the attention of APA, AWC, ICC-ES and ICC.
Jess Lohse (Rocky Mountain Truss) returns again this month to provide a component manufacturer's perspective on the contents of the new March issue. We hope you enjoy it as much as he seemed to!
Last summer, Superstorm Sandy caused an estimated $65 billion worth of damage in the U.S., a total surpassed only by Hurricane Katrina in American history. Sandy was the largest hurricane on record to hit the Atlantic Coast, at over 1,100 miles in diameter. So while it hit the New Jersey shores the hardest, according to the National Oceanic and Atmospheric Administration, its disastrous effects were felt as far inland as Wisconsin and Michigan.
While the chaos and destruction wrought by this powerful natural force is sobering, it’s hard not to simultaneously focus on the positive stories that came out of such events. One such story is that of Cussewago Truss LLC in Cambridge Springs, PA. It’s a tale of the marvels of wood, the value of engineering and the fruits of a well-executed plan.
