Brandy Alger explains the post-tensioned timber frame system that allows buildings to sway back and forth and then spring back into position after being shaken in an earthquake.

Loving the flow of content 👍👍

@hamishperkins2307 Год назад

Very interesting. Thanks for the videos.

Interesting examples . Have you explained The Papa's base isolation , or the residential building in Wellington on the old Cuba st Farmers site ?

@OutThereLearning Год назад

Coming up, witha Chch example...

Very innovative. Has this method been used for new builds here in Christchurch or elsewhere in NZ?

Does the rocking result in damage to the facade and interior of the building?

@mozismobile Год назад

my guess is that it's cheaper to replace facade elements than whole buildings. Not to mention more survivable for the occupants. The beehive is on big shock absorbers that isolate it from things, but it's kind of expensive to build a giant concrete "boat" that floats above the surrounding landscape.

@@mozismobile Yeah, that makes sense!

@michaelwoodhams7866 Год назад

I was wondering that. Here is one possible solution: imagine all your interior walls attach only to the floor and adjacent internal walls. Where internal walls meet external walls you have a seismic gap. Now the internal walls have low mass and high rigidity, which saves them from damage even if the floor shakes strongly, and the gaps protect the walls from being impacted by any other part of the building. The above is pure speculation on my part. I am not a civil engineer specializing in earthquake resistance.

You dont want the building to rock at all. That creates thrust energy x weight distrubution against each sigment of the building it will rock itself to self destruction. Te papa.
