"I don't know why I write science fiction. The voices in my head told me to!"

| House-of-Cards Construction | ||
| Architectural technique that uses computers to help buildings maintain their balance during earthquakes. |
Vinge tantalizes us with a glimpse at a future construction technique.
| Juan liked to sit by the outer wall, especially when the classroom was on the third floor. You could feel the wall sway gently back and forth as the building kept its balance. That sort of thing made his ma real nervous. "One second of system failure and everything will fall apart!" she had complained at a PTA meeting. On the other hand, house-of-cards construction was cheap - and it could handle a big earthquake almost as easily as it did the morning breeze. |

The implication is that a building of this kind is really like a self-balancing robot. Although most tall buildings today are built to flex with stresses like wind and mild earth tremors, as far as I know this is just an idea.
One technique that appears to be in current use is called the "isolated base" technology. This uses a flexible support placed between the foundation and the structure itself; it counteracts the motion of seismic waves. As the earthquake moves the foundation one way, the support moves the other way, and the building stays almost stationary.
I can't find anything on this kind of technique in actual use, but maybe a student of architecture or engineering could chime in.
