The only concern about time history analysis is that the input (random function) introduced as ground vibration in the system. Hard assumption to make e?? Different types of excitation activates different modal frequencies and mode shapes. There is no direct link with ambient.
However, there is...
The operational modal analysis is based on unknown input and known output. The latter means that the environmental and operational conditions are not known during testing, and the aim of the test is the accelerations. Secondly, the accelerations (time-series) transformed to spectral densities...
I would give a closer look tomorrow . I think that it would be helpful if you can send me one or two of hand-drawings of the bridge relative to the details-position of bearings, in order to give you a more detailed answer. See contact details in...
Hi Mohandes2018,
I`m also in Model updating, time-series analysis and modal identification of bridges.
In CSI bridge you can simulate the integration by going to the bridge bent data (in components menu) and checking the 'Girder support condition Integral'. As for the seating of the deck in...
Hi all,
I have a four-storey, three bay in x, and two bay in y RC building.
The calculated areas of both shear and longitudinal reinforcement in beams were ok. However, in columns, although I get the longitudinal reinforcement correctly, there is no shear reinforcement calculated.
Do anyone...
