Sine ( one-frequency-at-a-time ) tests are performed to survey the structural response of the device under test ( DUT ).

In the past decade, this observation leaded to the attraction of the theoretical studies toward the near-field effects of the earthquake rotational loading on the structural response.
13.
This is clearly not a linear resonance phenomenon, even if the bluff body has itself linear behaviour, since the exciting force amplitude is a nonlinear force of the structural response.
14.
Three PASDE canisters, located throughout the cargo bay, also photogrammetrically recorded structural response data of the " Mir " solar arrays during the docked phase of the mission.
15.
In fact, the SSI can have a detrimental effect on the structural response, and neglecting SSI in the analysis may lead to unsafe design for both the superstructure and the foundation.
16.
However, The design of the scaled structures under the partial similarity condition must follow a deliberate methodology to ensure the accuracy of the scaled structure in predicting the structural response of the prototype.
17.
Such wooden coasters, while limited in their path ( not supporting loops ), possess a certain ride character ( owing to structural response ) that is appreciated by fans of the type.
18.
An active vibration control system, known as the " active control of structural response system ", reduces airframe vibration by up to 80 % which increases crew comfort and minimises the buildup of stress on the airframe.
19.
However, the calculated response can be very sensitive to the characteristics of the individual ground motion used as seismic input; therefore, several analyses are required using different ground motion records to achieve a reliable estimation of the probabilistic distribution of structural response.
20.
The NIST report provides an analysis of the structural response of the building only up to the point where collapse begins, and asserts that the enormous kinetic energy transferred by the falling part of the building makes progressive collapse inevitable once an initial collapse occurs.
