Steel Fuses


It is the goal of structural steel designers to make a building with replaceable energy-absorbing elements, and then put the building back together again. They think from within their specialty, and wish to totally ignore the foundation, and the physics of the earthquake. Thus, we have had 'basement isolation', and all sorts of goodies.

Here is another one. Alright then students, what do they forget? They forget that a building is filled with all sorts of non-steel elements, like people, and waterbeds, and drywall. Hospitals are full of things that don't like to roll down unlevel floors. Yet, I can't totally get down on these things, because they now require decent real-time seismic analysis.

So, you will see these things installed, until something new comes along.
