Dynamic Model Tests, NORAD Combat Operations Center

摘要

A study is presented on the design and test of a model which is dynamically similar to the South Building of the NORAD Combat Operations Center complex. The primary objective of this investigation was to study the behavior of a shock isolated building module subjected to dynamic loading. The design of a scaled model and its important parameters are presented. Dynamic rigid body response of a building module mounted on coil springs has been analyzed. Theoretical scaling relationships and governing displacement-time histories and acceleration-time histories are derived. Test results and analyses with a comparison of the theoretical predictions are presented. The results show a verification of response predictions; it is concluded that response predictions for the actual facility to similar scaled inputs are valid. (Author)
