Speaker 1: Taxic.
Speaker 2: This is the seventy seven WABC Mini cast. Doctor Doulay
Speaker 2: is our special guest and what I wanted to get
Speaker 2: to doctor, and I appreciate your time as always is
Speaker 2: your connection to building risks and what happens with buildings today.
Speaker 2: That's another area of expertise. Describe that to the audience
Speaker 2: because it's a powerful thing in today, you know, blending
Speaker 2: architecture construction, how do we build safer buildings knowing what
Speaker 2: we know about earthquakes, so.
Speaker 1: We know that earthquakes bring shaking, and shaking is different
Speaker 1: than just the natural loads that we have. It shapes
Speaker 1: in three dimensions. It's left and right and up and down.
Speaker 1: So that creates, as we can imagine, it generates a
Speaker 1: lot of forces on buildings, so they need to be
Speaker 1: designed more safely. So those building codes that get updated regularly,
Speaker 1: and there's different techniques that are used to make buildings
Speaker 1: safer and so over the years, over the years of
Speaker 1: the building code improves, the newer buildings tend to be
Speaker 1: more resilient to earthquakes. The goal of the building code
Speaker 1: is to prevent collapse. And one thing that people don't
Speaker 1: tend to realize is that well something built to code
Speaker 1: doesn't mean that the building is usable after an earthquake.
Speaker 1: It can be damaged beyond repair. The goal is to
Speaker 1: save lives, so to really reduce the chances of collapse.
Speaker 1: But after that maybe it's it's too damage and needs
Speaker 1: to be torn down and rebuilt. So not on. Yeah,
Speaker 1: that's the purpose of the building code is really to
Speaker 1: save lives, not necessarily to make a building last forever.
Speaker 2: Absolutely, Am I correct? Doctor? And this assessment I've read somewhere.
Speaker 2: Can't see where I read this, but I think it's
Speaker 2: in the back of my head that on certain tall
Speaker 2: superstructure buildings they have this gigantic weight or something up
Speaker 2: on the very top of the building, not outside, but inside,
Speaker 2: so that when the building swighs by wind. Describe that?
Speaker 2: Am I correct in this? Am I describing it correctly?
Speaker 1: Yes, it exists. It's called the act. There's active or
Speaker 1: fastive tune dampers, so it's a massive There's one that
Speaker 1: you can find videos that are amazing online in Taiwan.
Speaker 1: I think it's the Taipa Tower and maybe I got there.
Speaker 1: If you just search Taiwan earthquake damper, people find that
Speaker 1: there's videos of that.
Speaker 2: That's a tough one to say, right, yeah, so some some.
Speaker 1: Are so you have the weight on top to to
Speaker 1: to reduce the motion on top because the building it
Speaker 1: shakes at the bottom, but the waves move and it
Speaker 1: wants to make the top move a lot. And so
Speaker 1: these big some of them are are are moved and controlled.
Speaker 1: But just the fact that you have a lot of
Speaker 1: weight on top if it uses the motion on the
Speaker 1: top and so, and it's awful useful for those very
Speaker 1: tall buildings when there's a lot of wind because people
Speaker 1: sometimes get seasick even from the motion in tall Oh yeah.
Speaker 2: Never thought about that. And look at builds, big structures
Speaker 2: like the birds Khalifa, I mean, in other buildings, it
Speaker 2: looks like they're continuing to build. I've read somewhere I
Speaker 2: think Saudi Arabia is looking to build a building that's
Speaker 2: what well upwards I think of, even like a half
Speaker 2: a mile. Maybe I'm incorrect, but I hope they're paying
Speaker 2: strict attention to what's under that ground. Obviously,
