Thailand/Myanmar Earthquake: VIDEO Dramatic collapse of a high rise in Bankok 2

[human909]

I have no engineering commentary at this stage. But this does capture a near complete collapse:

Greg, maybe they need to design the sides of the pool to mimic a re-entrant combustion chamber so the water doesn't spill out to reduce the mass damping effect.

Viewed a very long apparently government report yesterday on Youtube. Cannot find it today. Very critical of the situation. Apparently AI composed as I have never seen such a complete report this soon. I searched YouTube and Perplexity for the report; maybe there are better sources some place. Some discussion on the quality of the rebar and the history of the construction. Interesting to note that this is a government building and lots of flat post tensioned slabs and sections.

Found much interesting comments and discussions on X. Getting to be my go to source - but still being careful. Center core column structure and flat slab construction. Similar to construction in the 60's that I am familiar with.

Video clip (half speed) of the south elevation, isolated at the left column/floor connection (higher resolution attached). Although this approach eliminates most indication of structural oscillation, it does show the significant east/west sway of the crane, and by inference, that of the structure.



If the core west elevation load path is compromised (fuchsia), the burden increasingly falls on the north/south elevations. The core pass-through configuration from floor to floor can create a scenario where that load is increasingly concentrated on a smaller support element at the lower floors, which would be the final point of failure prior to the collapse.
