Interesting articles in Spring 2008 Aspire Concrete Bridge magazine, showing the type of damage that can occur from a rail tanker fire.

You might need to right-click and download the PDFs for the "Protect" and "Evaluate" articles.

Here's an article about a sustained fire under the Interstate-85 bridge in Atlanta in March 2017.

Note:
• I am not a civil engineer, and have no access to damage assessments
• the rail tanker fire on the #CrimeaBridge was on, not under the bridge

usatoday.com/story/news/201…
Sample engineering assessment of damage to road bridge after rail tanker fire underneath it.
• important to know what burned and for how long
• Figure 3 shows the mapping of certain damage indicators to the piers near, and span above, the rail tanker.

If this photo is accurate:
• rail bed beside burnt car appears to have sunk 10-15 cm
• some concrete sleepers appear to be missing there
• steel channel without sleepers between the rails is missing
• side of bridge behind men appears to have sagged

Image
Don't know when this video was taken, but while these cranes are on the bridge trying to remove the rail cars (hours? days?) it is doubtful trains can travel on the other tracks.

Especially if the cranes need the tracks during any part of the operation.

This part of the bridge appears to be where the sunken rail bed is in other photos.

I am not a civil engineer or railway specialist, but I would expect a detailed damage assessment like this (or better) before using that bridge.

Closer video of damage to the structure of the bridge.

Both upper and lower steel maintenance walkways have melted and sagged. This steel failure is an indicator of the heat energy coming from the tanker fires.
Even after the blast, how bad is Russia's security on Crimean Bridge? Even on the rail bridge, someone is openly taking video, then uploading:
• repair progress
• rail and rail bed damage
• which suggest how much heat released
• road bridge damage

Repair progress. At the time of video, of the 7 tank cars that caught fire:
• 2 complete cars remain on rails
• 1 car has tank removed, but frame and bogies remain, still coupled to next car's bogie
• 2 cars have 4 bogies left
• 2 cars fully removed

en.wikipedia.org/wiki/Bogie
The heat is so intense that:
• the rail under the wheels collapsed
• the rail car axles warped

Priceless information for fire investigators, civil engineers, metallurgical engineers, bomb damage experts. ImageImage
Two days ago, @zahed gave an initial assessment from the photos & videos available then. His civil engineering degree gives him a better foundation to understand them than my industrial systems engineering degree. I'm following now for any updates.

Image
@zahed Rail bed damage.
• apparent sinking under 2 remaining tanker cars
• crushed stone between concrete sleepers missing
• suggests damage to underlying box structure

Maybe bridge is too weak to bring back cranes to lift tanks off, and rail too damaged to pull those cars away. ImageImage
@zahed It seems:
• on one end of the fire, bogies & wheels have fused from the heat and cannot be pulled
• on the other end, the rail bed and underlying structure are too weak to bring back the cranes

This might be why all the people in orange vests are there: looking for solutions. ImageImageImageImage
@zahed This video also show poor state of road bridge:
• intentionally bottlenecked to one lane
• red/white barriers adjacent to remaining rail cars
• no traffic on it - people on foot looking at it
• deflection and slant obvious, matches earlier video released by Russia ImageImageImageImage
@zahed Around 20-second mark of earlier video from a car driving off that damaged section of road bridge, you hear a kerthunk.

This might be normal for such joints, or it may be from a larger deflection due to the explosion destroying the adjacent road span.

Image
This @ConversationUK article released a few hours before the video from atop the rail bridge has 2 engineering professors - experts in bridge safety and blast engineering - assessing the damage revealed at the time. I'm interested in their updates too.

Thread regarding Danielle Smith's @gofundme Fundraiser and her oath of office for Premier tomorrow.

I have questions & concerns.

gofundme.com/f/right-to-try…
@gofundme The image for Smith's fundraiser started Sun 19 Sep 2021 is about first of two stated objectives:

"ask the court to force the government to make the J&J Janssen vaccine available to Canadians."

This objective appears bogus + dangerous. Here's why.

covid-vaccine.canada.ca/jcovden/produc… Top of Smith's GoFundMe sho...Health Canada's regulatory ...
Since 30 April 2021, Health Canada has publicly warned about the failed inspection of Janssen's US supplier, Emergent Biosolutions in Baltimore.

Health Canada learned that even Janssen vax received from another country had ingredients from Emergent.

Sunday Brunch at Hotel Blackfoot, with my custom omelet, overlooking the pool. 10am to 2pm.

I raid the buffet anonymously like a dark-haired Viking in a respirator, then come out here to eat, treated like a King.

Food pics later; I’m eating.
Interim progress report.
Clearly, it was time to return to the buffet. I went back for seconds.

They gave me permission to film the buffet, so I’ll share that later on this thread.

For now 😋🤤

This lawsuit against:
• Decision by CMOH to lift #COVID19AB mask mandate in schools
• Prohibition by Education Min LaGrange preventing school boards from keeping them as policy
• goes to trial 17-18 Aug
• just in time for school

Please help fund it:

Any reporters covering (or lawyers live-tweeting) 2-day hearing Wed 17 & Thu 18 Aug? Justice Dunlop in QB Edmonton.

@MBellefontaine @cspotweet @cfrangou @KevinCTV @Adam_Toy @Lorian_H @UbakaOgbogu @CAAerosolCltn @FlukerShaun @BankesNigel @cbcjanjohnston @KMartinCourts @CBCMeg I've been very interested in this lawsuit since I heard of it.

I'm not a party, witness or lawyer, but have seen some of the public documents, and related court decisions across Canada.

I will explain here my understanding, with links to the source documents, and screenshots.

Encouraged by @Sharonadactyl gratitude for public input on Alberta's school mask lawsuit, I am providing a 🧵of observations to stimulate input from other members of the public.

I had a good nap this evening, so here goes.

/c @OrlaghOKelly1 @gilmcgowan
The documents are here, and I would encourage others in the public, especially those skilled in science and medicine, to provide input by tweet, DM or email.

I am not a party to the lawsuit, nor employed by the lawyers or AFL. Just a private citizen.

Here from the Court decision released 19 May:

[67] In addition, on my own motion, I order Dr. Hinshaw to provide a better Certified Record of Proceedings, as set out above, by May 27, 2022, or such other date as the parties agree, or I order.

Alberta continues to burn deeper into exponential growth of COVID-19, worse than any other province.

Led by Calgary, by far worst in Canada, with cases doubling every 4.2 Generation cycles, at 3.5 days/cycle = doubling every ~14 days.

Joined by Edmonton. Central & North close.
Both the daily R from @imgrund and semi-weekly Wastewater Sampling at @ucalgaryCHI are leading indicators of #COVID19AB prevalence, ~5 days ahead of PCR.

Calgary has not recovered from 6th Wave, which GoA launched w rushed drop of safety measures through Feb (latest data 2 Jun).
@imgrund @ucalgaryCHI More recent wastewater sampling shows:
• Edmonton had more pronounced surge in May, and is rising again
• Medicine Hat & High River rising again
• Banff never recovered from May surge

We're sitting ducks for Omicron's ongoing mutation without (proven, simple) safety measures.

On Wednesday, Health Min Copping "addressed the speculation" about funding cuts to Rapid Test distribution. He said compensation was "changed" from $5/test to $60/case.

Suspicious of the change in units, I looked into it.

Compensation has been cut from $5/test to $0.093/test.
If you're going to lead off weekly #COVID19AB theatre to say "rumours are not correct", then your clarification had better not be deceptive.

This would be the Labour Min saying Alberta's minimum wage has been "changed" from $15/hr to $500/month.

This compensation cut to pharmacists was announced in a PDF dated 3 March 2022, effective 7 March.

Goodbye $5/test dispensing fee.

Hello flat $60/case (for eg. 650 BTNX) the pharmacist has to apply for, to cover shipping directly billed by distributor.
