Dolmsund bridge (object state)
A condition of an object at a particular time, reflecting the object's ability to fulfil it's requirements.

Summary
:
The strain measurements from the bridge are compared to calculations from the design program NovaDesign. The comparison shows good compliance during the construction phases. Deviations occur after the two cantilevers are connected. Especially the bending strains in the main columns, where NovaDesign overestimates the difference between the strains in each side of the column. The normal strains from the programe shows good compliance compared to the measurements. The deviations may come frome differences in the rigidity between the column and the bridge deck as well as the effects from rebars in the columns. The length differences during the construction phases come from the functions of creep, shrinkage and temperature. Measurements from the bearings have been used to analyse how the mean temperature affects the length of the bridge. A review of the measurments of the bearings adjusted for temperature shows the rate of contraction in the bridge due to creep and shrinkage. It is shown that the rate of contraction in the bridge is higher while the concrete is newly cast.
