What a fantastic presentation from our experts! Want to learn more about this urgent issue? Let's talk at #Transpo2024 about how vessel collision impact mitigation helps keep Florida transportation moving!!! #MoffattNichol #CreativePeoplePracticalSolutions
With the increasing size and number of ships in our waterways, it's essential to assess the risks they pose to bridge structures. Moffatt & Nichol’s experts, Mike Knott and Mike Winters, have spent decades engineering solutions to mitigate vessel collision impacts on marine structures. Join them at the University Transportation Research Center’s Virtual Symposium on Protection of Bridge Piers from Large Ship Impact. Engage with leading experts as they address this urgent issue. For more information, visit https://ow.ly/ZVQm50SJpZh. Registration is free at https://lnkd.in/g_FRGFnb

Public display is still the best tool to shake perceptions; in this case, it is wood's durability. In Leonardo da Vinci's design, wood is always under compression, where it performs best. It's strong when compressed along the grain, though it's terrible under tension or when compressed perpendicular to the grain. However, as this demo shows, it's strong in axial compression along the length of the fibers. Imagine how much better it performs when you apply modern engineering advancements in laminated wood, resulting in a stronger, more durable, and potentially more sustainable structure than one made with traditional wood. Did you know mass timber is excellent for long-span structures, including long-span bridges? In our design for replacing the crumbling West Seattle Bridge, we proposed mass timber in composite hangers that take on sporadic compressional seismic and wind loads. Design constantly evolves, and some 500-year-old innovations continue to inspire new possibilities!
ONLY TIMBER 🪵 No screws, no ropes, no steel fasteners of any kind in the Da Vinci bridge demonstrator 🌍 The special highlight of Dach + Holz was a demonstration of a Da Vinci wooden bridge. The construction principle Leonardo da Vinci (1452 to 1519) invented. Timber is wedged into each other in such a way that they support each other. Neither screws nor ropes are necessary to be able to build and load the bridge. In order to prove the load capacity of the bridge, but also to demonstrate the load-bearing capacity of the building material wood, a heavy electric vehicle drove over the bridge.

This morning my two good colleagues Nicolai Skovsager Bang-Lauritsen and Søren Rud Pedersen delivered a compelling “product showcase presentation” at the Society of Fire Protection Engineers (SFPE) conference in Copenhagen, highlighting why ROCKWOOL’s insulation has been the preferred choice for passive fire protection in some of the world’s largest wooden structures. An additional important focus of the session was the impending challenge with the large role out of PV installations on roofs. PV installations are a key technology in the green transition and no doubt they are best placed on the large roof areas found on e.g. logistic and storage warehouses, when they are prepared for it! However, several critical considerations must be addressed when selecting solutions and materials for these rooftops: 1. The emergence of a new ignition hazard from the exterior of the roof 2. The impact of PV panels on fire dynamics 3. Ensuring the roof’s resilience against fires originating from an outside sources. 4. Understanding how the presence of PV panels affect the firefighting operation in the event of a fire. For further insights on determining when a roof is ready for PV panels, refer to our guideline on Solar panels (https://lnkd.in/dFpeDvKu).

How did the 𝐅𝐫𝐞𝐧𝐜𝐡 𝐑𝐞𝐯𝐨𝐥𝐮𝐭𝐢𝐨𝐧, 𝐭𝐡𝐞 𝐍𝐚𝐩𝐨𝐥𝐞𝐨𝐧𝐢𝐜 𝐖𝐚𝐫𝐬, 𝐚𝐧𝐝 𝐁𝐫𝐢𝐭𝐚𝐢𝐧’𝐬 𝐈𝐧𝐝𝐮𝐬𝐭𝐫𝐢𝐚𝐥 𝐑𝐞𝐯𝐨𝐥𝐮𝐭𝐢𝐨𝐧 bring about the need for creosote-treated wood for modern infrastructure? England viewed its conflict with a revolutionary France as an existential “threat to European civilization,” and relied heavily on the British Royal Navy for survival. However, “decay [and attack from ship-worms] in the timbers of their ships was taking a heavier toll of both her fighting and her cargo vessels than all of her enemies combined.” The director general of the British Navy’s medical department himself got involved in wood preservation science, 𝐨𝐛𝐭𝐚𝐢𝐧𝐢𝐧𝐠 𝐚 𝐩𝐚𝐭𝐞𝐧𝐭 𝐟𝐨𝐫 𝐚 𝐰𝐨𝐨𝐝 𝐩𝐫𝐞𝐬𝐞𝐫𝐯𝐚𝐭𝐢𝐨𝐧 𝐦𝐞𝐭𝐡𝐨𝐝 𝐢𝐧 1838. The use of 𝐜𝐨𝐚𝐥-𝐭𝐚𝐫 𝐜𝐫𝐞𝐨𝐬𝐨𝐭𝐞 𝐟𝐨𝐫 𝐰𝐨𝐨𝐝 𝐩𝐫𝐞𝐬𝐞𝐫𝐯𝐚𝐭𝐢𝐨𝐧 was patented in 1836 by Franz Moll, and two years later John Bethell created a “pressure impregnation process” which enabled creosote to be much more effectively applied to timber. Known as the Bethell Process, or “full-cell” process, John Bethell’s 1838 innovation quickly became the 𝐦𝐨𝐬𝐭 𝐬𝐮𝐜𝐜𝐞𝐬𝐬𝐟𝐮𝐥 𝐟𝐨𝐫 𝐭𝐫𝐞𝐚𝐭𝐢𝐧𝐠 𝐰𝐨𝐨𝐝 𝐚𝐧𝐝 𝐜𝐨𝐧𝐭𝐢𝐧𝐮𝐞𝐬 𝐭𝐨 𝐬𝐞𝐫𝐯𝐞 𝐚𝐬 𝐭𝐡𝐞 𝐟𝐨𝐮𝐧𝐝𝐚𝐭𝐢𝐨𝐧 𝐨𝐟 𝐭𝐡𝐞 𝐰𝐨𝐨𝐝 𝐩𝐫𝐞𝐬𝐞𝐫𝐯𝐚𝐭𝐢𝐨𝐧 𝐢𝐧𝐝𝐮𝐬𝐭𝐫𝐲. In the latter half of the 19th century, American industrialists adopted the technologies that had been pioneered in England. Rather than wartime and naval battles, in America demand for wood preservation was driven by the emerging railroad industry. Want to learn more?

As a chairman of a local board of zoning appeals, I regularly hear, "That business has a huge roof, make them put solar panels up there instead of creating new solar farms." Not so fast, folks. Phil Dregger, PE, RRC explains how to do this in a responsible fashion this week. Be sure to catch his presentation!
Phil Dregger, PE, RRC of Salas O’Brien is presenting 𝘚𝘰𝘭𝘢𝘳 𝘙𝘦𝘢𝘥𝘺 𝘙𝘰𝘰𝘧𝘴 𝘵𝘩𝘢𝘵 𝘈𝘳𝘦𝘯’𝘵 – 𝘏𝘰𝘸 𝘵𝘰 𝘗𝘳𝘰𝘵𝘦𝘤𝘵 𝘠𝘰𝘶𝘳 𝘊𝘭𝘪𝘦𝘯𝘵 𝘢𝘯𝘥 𝘠𝘰𝘶𝘳𝘴𝘦𝘭𝘧 this week at the 23rd Annual IIBEC Southern California Chapter Winter Workshop at the Aulani Resort on January 19th. Learn more: https://lnkd.in/g2ZkFGRp

In some cases it is necessary to control frost heave and thaw consolidation related movements when freezing near structures. This recent paper presented at the International Symposium on Ground Freezing (London 2023) describes an complex approach to this problem. Another example of Keller's ground freezing capabilities. https://lnkd.in/eKkUJJfv
