Comparison of the displacement time history curves between various structures reveals that after demolition of corner column the top displacement at demolition site of 10-story frame-shear structure is at the highest level, which is about 1/100 of the span of the long-side frame beam.
Under the conditions of the given support displacement excitation amplitude and excitation frequency and displacement time history of which actual effect on cable end is feedback from displacement sensor at the tip of the actuator to MTS controller and is recorded, the true displacement time history signal and corresponding amplitude-frequency characteristic curve under the two working conditions are shown in Figures 15 and 17, respectively.
From actuator displacement time history in Figures 6 and 17 we can see that although displacement excitation amplitude instruction sending to the actuator is [W.sub.B] = 3 mm and [W.sub.B] = 5 mm, the actual displacement excitation amplitude which interacts on bridge support did not be reached, which is lower than the given value, and they are [W.sub.B] = 2.5 mm and [W.sub.B] = 4 mm, respectively; the excitation frequency can be obtained from the spectrum curve, [[omega].sub.B] = 4.763 Hz and [[omega].sub.B] = 4.766 Hz, respectively, which are also not the given value 4.90 Hz, so in the process of numerical simulation, the excitation amplitude and frequency of bridge bearing should be analyzed by adopting the real value of the actuator, which is reliable and effective.
