    Quizzical Pursuit
    —The Architecture Puzzler

    Created by Dave Guadagni

    Solution to Last Week's Puzzler
    Architecture Puzzler #94

    Question

    Suppose you designed a "viscous damper" to minimize rotation placed on a moment frame joint during an earthquake. How would you describe this design to your client?

    Answer

    A viscous damper can be thought of as a shock absorber about 10 feet (3 meters) long placed on the top of a shear wall. It allows the shear wall to transmit energy from its diaphragm to the structure frame over a period of microseconds rather than all at once.
     


     

    Okay, got it? Now try this week's Puzzler:
