FITTING MODEL PARAMETERS OF PRESTRESSED CONCRETE BRIDGE: COMPUTATIONAL ASPECTS

Abstract eng:
Many tasks, in our case fitting parameters of a numerical model, need enormous computing time that is not usually easily accessible. Here enormous means many days or months when a common computer is used. Nowadays there exists a possibility to utilize distributed resources like grid or volunteer computing. This contribution is focused on an application of distributed computing for fitting model parameters of a real structure. We are focused on a three-span prestressed concrete bridge in Mělník. This 23 years old bridge has a serious problem with an excessive deflection. The evaluation of monitoring results clearly shows that after 23 years since putting the bridge into operation the deflection is still growing.
