00:00:03.439 --> 00:00:03.799
<v Speaker 1>Taxic.

2
00:00:05.440 --> 00:00:11.880
<v Speaker 2>This is the seventy seven WABC Mini cast. Doctor Doulay

3
00:00:12.000 --> 00:00:14.039
<v Speaker 2>is our special guest and what I wanted to get

4
00:00:14.080 --> 00:00:17.000
<v Speaker 2>to doctor, and I appreciate your time as always is

5
00:00:17.120 --> 00:00:21.280
<v Speaker 2>your connection to building risks and what happens with buildings today.

6
00:00:21.359 --> 00:00:24.239
<v Speaker 2>That's another area of expertise. Describe that to the audience

7
00:00:24.280 --> 00:00:27.839
<v Speaker 2>because it's a powerful thing in today, you know, blending

8
00:00:27.920 --> 00:00:32.079
<v Speaker 2>architecture construction, how do we build safer buildings knowing what

9
00:00:32.119 --> 00:00:34.719
<v Speaker 2>we know about earthquakes, so.

10
00:00:34.719 --> 00:00:38.600
<v Speaker 1>We know that earthquakes bring shaking, and shaking is different

11
00:00:38.679 --> 00:00:42.600
<v Speaker 1>than just the natural loads that we have. It shapes

12
00:00:42.640 --> 00:00:45.840
<v Speaker 1>in three dimensions. It's left and right and up and down.

13
00:00:46.479 --> 00:00:50.399
<v Speaker 1>So that creates, as we can imagine, it generates a

14
00:00:50.439 --> 00:00:53.359
<v Speaker 1>lot of forces on buildings, so they need to be

15
00:00:53.439 --> 00:00:59.359
<v Speaker 1>designed more safely. So those building codes that get updated regularly,

16
00:00:59.840 --> 00:01:04.640
<v Speaker 1>and there's different techniques that are used to make buildings

17
00:01:04.640 --> 00:01:12.359
<v Speaker 1>safer and so over the years, over the years of

18
00:01:12.519 --> 00:01:16.000
<v Speaker 1>the building code improves, the newer buildings tend to be

19
00:01:17.040 --> 00:01:22.239
<v Speaker 1>more resilient to earthquakes. The goal of the building code

20
00:01:22.239 --> 00:01:25.480
<v Speaker 1>is to prevent collapse. And one thing that people don't

21
00:01:25.519 --> 00:01:29.040
<v Speaker 1>tend to realize is that well something built to code

22
00:01:29.079 --> 00:01:32.000
<v Speaker 1>doesn't mean that the building is usable after an earthquake.

23
00:01:32.400 --> 00:01:36.239
<v Speaker 1>It can be damaged beyond repair. The goal is to

24
00:01:36.319 --> 00:01:42.519
<v Speaker 1>save lives, so to really reduce the chances of collapse.

25
00:01:42.640 --> 00:01:45.920
<v Speaker 1>But after that maybe it's it's too damage and needs

26
00:01:45.959 --> 00:01:51.120
<v Speaker 1>to be torn down and rebuilt. So not on. Yeah,

27
00:01:51.200 --> 00:01:53.840
<v Speaker 1>that's the purpose of the building code is really to

28
00:01:53.920 --> 00:01:57.480
<v Speaker 1>save lives, not necessarily to make a building last forever.

29
00:01:58.159 --> 00:02:01.599
<v Speaker 2>Absolutely, Am I correct? Doctor? And this assessment I've read somewhere.

30
00:02:02.040 --> 00:02:03.959
<v Speaker 2>Can't see where I read this, but I think it's

31
00:02:03.959 --> 00:02:05.719
<v Speaker 2>in the back of my head that on certain tall

32
00:02:05.760 --> 00:02:10.319
<v Speaker 2>superstructure buildings they have this gigantic weight or something up

33
00:02:10.400 --> 00:02:13.400
<v Speaker 2>on the very top of the building, not outside, but inside,

34
00:02:13.719 --> 00:02:16.360
<v Speaker 2>so that when the building swighs by wind. Describe that?

35
00:02:16.520 --> 00:02:18.719
<v Speaker 2>Am I correct in this? Am I describing it correctly?

36
00:02:18.800 --> 00:02:22.400
<v Speaker 1>Yes, it exists. It's called the act. There's active or

37
00:02:22.439 --> 00:02:26.400
<v Speaker 1>fastive tune dampers, so it's a massive There's one that

38
00:02:26.639 --> 00:02:30.360
<v Speaker 1>you can find videos that are amazing online in Taiwan.

39
00:02:30.919 --> 00:02:34.879
<v Speaker 1>I think it's the Taipa Tower and maybe I got there.

40
00:02:35.240 --> 00:02:40.479
<v Speaker 1>If you just search Taiwan earthquake damper, people find that

41
00:02:40.520 --> 00:02:42.080
<v Speaker 1>there's videos of that.

42
00:02:41.719 --> 00:02:45.199
<v Speaker 2>That's a tough one to say, right, yeah, so some some.

43
00:02:45.400 --> 00:02:49.560
<v Speaker 1>Are so you have the weight on top to to

44
00:02:49.560 --> 00:02:53.199
<v Speaker 1>to reduce the motion on top because the building it

45
00:02:53.360 --> 00:02:56.080
<v Speaker 1>shakes at the bottom, but the waves move and it

46
00:02:56.280 --> 00:02:59.159
<v Speaker 1>wants to make the top move a lot. And so

47
00:02:59.319 --> 00:03:03.560
<v Speaker 1>these big some of them are are are moved and controlled.

48
00:03:03.919 --> 00:03:05.560
<v Speaker 1>But just the fact that you have a lot of

49
00:03:05.680 --> 00:03:09.199
<v Speaker 1>weight on top if it uses the motion on the

50
00:03:09.319 --> 00:03:12.560
<v Speaker 1>top and so, and it's awful useful for those very

51
00:03:12.560 --> 00:03:15.120
<v Speaker 1>tall buildings when there's a lot of wind because people

52
00:03:15.479 --> 00:03:20.400
<v Speaker 1>sometimes get seasick even from the motion in tall Oh yeah.

53
00:03:20.639 --> 00:03:23.319
<v Speaker 2>Never thought about that. And look at builds, big structures

54
00:03:23.319 --> 00:03:25.680
<v Speaker 2>like the birds Khalifa, I mean, in other buildings, it

55
00:03:25.680 --> 00:03:27.919
<v Speaker 2>looks like they're continuing to build. I've read somewhere I

56
00:03:27.919 --> 00:03:30.879
<v Speaker 2>think Saudi Arabia is looking to build a building that's

57
00:03:30.879 --> 00:03:33.680
<v Speaker 2>what well upwards I think of, even like a half

58
00:03:33.719 --> 00:03:36.599
<v Speaker 2>a mile. Maybe I'm incorrect, but I hope they're paying

59
00:03:36.639 --> 00:03:39.439
<v Speaker 2>strict attention to what's under that ground. Obviously,
