Ambient Vibration Tests at Some Buttress Dams in Romania

Ambient Vibration Tests of Structures − a Review

A literature review on the subject of ambient vibration testing is presented, and a review of a recent study to illustrate state-of-the-art in the application of the ambient vibration method. Reports on testing of full-scale structures by the ambient vibration method began to appear regularly around 1970, with about 3/4 of all contributions devoted to the experiments in buildings, dams, chimney...

Ambient vibration tests of a cross-laminated timber building

A Study of Dynamic Characteristics of a Multistory Building Using Ambient Vibration Tests (TECHNICAL NOTE)

Dynamic characteristics of a typical multistory building in Iran have been studied in two different stages of building construction, using ambient vibration tests. Finite element models have also been used to determine these characteristics and to verify test results. The results indicated the agreements and also differences between conventional theoretical models and the behaviour of real stru...

Ambient habitat noise and vibration at the Georgia Aquarium.

Underwater and in-air noise evaluations were completed in performance pool systems at Georgia Aquarium under normal operating conditions and with performance sound tracks playing. Ambient sound pressure levels at in-pool locations, with corresponding vibration measures from life support system (LSS) pumps, were measured in operating configurations, from shut down to full operation. Results indi...

Comparisons between Ambient and Forced Vibration Experiments

The ambient and forced vibration techniques for testing full-scale structures are critically compared. Both methods, based on small level excitation, may be used to determine many mode shapes and frequencies of vibration and the corresponding damping values, with adequate accuracy for most purposes. The two techniques give mutually consistent results. The mode amplitudes determined by ambient a...
