Could the Baltimore Bridge have been saved? YES!
This video shows how the Baltimore Bridge could have been saved. The video also shows that modern bridge code equations would have predicted that the collapse would have happened. Details are given about why the collapse happened and what could have been done to prevent it. A responsibility framework is also presented that can be used to prevent future collapses.

    Hi Tyler Do you have videos on the following topics ? 1. Thermal properties of concrete structures 2. The effect of thermal shock on concrete material 3. The durability effect high temperatures have on existing concrete. , does the rise in temperatures are shortening the life of concrete infrastructure ? 4. Is it possible to measure the water flowing through cracks ? 5. Repairing cracks with movement ? Perhaps in elevated slab ?

    Excellent video, Tyler. Might be worth pointing out that for metric the stated relationships between the compressive and flexural/shear strengths are only valid for imperial units. As 1 psi = 0.0069MPa, *Flexural strength* 7.5*sqrt(Fc_psi) -> 7.5*sqrt(0.0069*Fc_MPa) = 0.62*sqrt(Fc_MPa). *Shear strength* 4*sqrt(Fc_psi) -> 4*sqrt(0.0069*Fc_MPa) = 0.33*sqrt(Fc_Mpa)

  • @m00ndog3
    @m00ndog3 12 днів тому

    Why is the rebar/remesh in the middle or upper third of a slab? In a beam the tensile stress is at the bottom, unless its cantilevered, so it seems sensible that the rebar should be in the bottom third of a slab when thinking of the tensile stress being greatest at the bottom surface. Also, consecrators commonly 'cut' the upper third of the slab, wouldn't this cut hit rebar then?

    I know its been years now since this video was made but FRP rebar is now similarly priced if not even cheaper than steel rebar now. Some of the new FRP rebars are both strong and flexible now as well where they dont fracture as easily and will bend and flex back in place which solves some of the ductile concerns compared to steel.

    Thank you very much for making this video. When I see failures like this, I often think that something preventative could have been done, so it's good to hear what, specifically, that thing is, and that an overall template for the engineering exists. What I have to wonder about is the design of the permitting process. When the regulations were being changed, the permitting process should have required all the necessary modifications prior to the permit being granted. This process either was inadequatly designed regarding its primary objective, or it was too easy to subvert.
