"Spaced" column with high buckling prevention.
Joerg Stamm, Colombia
Bamboo skyscrapers? Sounds like an utopia, but actually, it's structurally possible to splice column "clusters" of culms all the way up in bracing spirals.
Preparing spaced column
Yogyakarta 2013: A five-story bamboo café built without structural engineers. It demonstrates bamboo's intuitive structural properties.
When inspecting the top floor a swaying feeling was noticed, just like during an earthquake. This indicates that bamboo is resilient to seismic impact.

The great CO2 sink capacity makes fast-growing bamboo an obvious large-scale option for construction materials.Multi-story - at a reasonable density - because of the never-ending suburban sprawl with more transport nightmares, paralyzing the economy...
Seismic safe connection
The recent structural engineering studies concluded that the L-shape columns can take on considerable weight if prevented from buckling.(50 MPa compression) With the Double Decker Beam an option could be heavy floor slabs, filled with adobe and sand as when pumping concrete. This would contribute to the vertical sound and fire insulation between apartments.
The L-shape column and the Double Decker Beam permit seamless embedding in honeycomb flush walls.
