Robust, or Risky? What Makes an Earthquake-Resistant Building

A skyscraper's credentials aren't visible from the sidewalk, but you can rest assured that steel is more pliable than brick or concrete, and that modern skyscrapers are subject to stringent seismic standards. "You don't just want to build something that's stronger, you want to be able to control where it gives," engineer Aaron Reynolds says. To do that, architects add "dog bones" to the frame?areas of reduced width on the building's steel beams. These weak zones absorb shaking, diverting strain from its welded joints. If you're inside a high-rise during a quake, stay put; you run a greater risk of being hit by debris outside.
