Science Buddies: "Ask an Expert"

Hello, I was wondering if anyone knew which is better: base isolation or tuned mass damper and the scientific principles behind it. Thanks.

Hello mewto,

Are you planning a hands-on science project? If you are, please provide more information about your project, including your hypothesis and the experiments to test that. This forum is for students who are doing hands-on science projects. Otherwise, there are other sites on the web where your questions would be more appropriate.

Thanks!

Hello. Thanks for replying. Let me elaborate further. I'm planning an experiment in which I'll be comparing tuned mass damper and base isolation. I'll be using 2 structures, and fitting one with with a tuned mass damper, and another with base isolators. However, I have some questions. For one, I don't have a hypothesis yet b/c I don't know the scientific principles behind them well enough to compare the two methods. I also don't know how I'll be constructing the tuned mass damper and the base isolators. In addition, I'm not sure how I'll measure the reaction of each structure to the shake table. So it would be awesome if anyone could please tell me about some scientific principles behind the 2 techniques so that I can better conduct this experiment.

Hello mewto,

You have interesting questions, however, these forums are for students (and their teachers and parents) in grades K-12 who are doing hands-on science projects.

You are welcome to browse the Science Buddies project database but the experts here have limited time and must focus on the students.

Here's a link to some discussion regarding shake tables.

Hi mewto,

In addition to the resources Madeline pointed out, you might also find the following discussion of earthquake-resistant building designs interesting:

There is also a YouTube video describing what a science fair experiment that explores how base isolation and tuned mass dampers perform in making a building "earthquake-proof:"

Hope this helps!
