- Description
- Bridge dynamic properties measured under a given vibration intensity condition would give a true picture of the behaviour for that particular condition. However, the use of the model derived from such data may not be reliable when applied
for the prediction of response under a different vibration intensity condition. Therefore, it is necessary to investigate the structural dynamic behaviour at different levels of excitation in detail. This paper focuses on the experimental investigation of modal property variability at different levels of excitation. Both weak ambient vibration tests
(induced by nearby traffic, wind and possibly microtremors) and forced vibration tests
with different applied input force induced by eccentric mass shakers were performed on
the Nelson St off-ramp bridge (an 11-span post-tensioned concrete, box girder structure forming a part of the motorway network in Auckland’s CBD). Three separate system identification methods, namely peak-picking (PP), the frequency domain decomposition (FDD) and the data-driven stochastic subspace identification (SSI) method, were applied
for accurate structural modal parameter identification. It was found that the three output
only identification techniques are able to extract natural frequencies of the structure reliably, while the time domain SSI method yields the best mode shape estimates and PP may not be able to give accurate mode shape estimates for some modes. The variability of the dynamic properties for the 1st vertical and lateral bending modes was examined. A
general trend of decreasing natural frequencies and increasing damping ratios was observed with increased level of vibration intensity.

- Study on the fundamental period of vibration of steel moment resisting frames

- Keywords: Fundamental period ; Eurocode 8 ; Drift limitations ; Moment resisting frames
- Description
- This paper aims at addressing the variation of fundamental period when the ductility and the damageability criteria varies. In order to investigate the influence of drift limitation on the fundamental period of vibration a huge parametric study using modal dynamic analysis, composed of 144 designed cases of steel moment resisting frames has been conducted. These are compared with the code prescribed fundamental period. It is observed that as the drift limitation varies from the more relax to the most stringent the fundamental period decreases and therefore the stiffness of the frame increases. The obtained period from the code are in the same range to the one obtained from the modal analysis when the strict drift limit is employed in the design.
