Abstract:
This research paper demonstrates the use of a new crack control model, described in detail in PART I of the series, based on the results of in-place analyses of semi-massive reinforced concrete (RC) tank wall segments. The following results of the measurements are presented: changes in the temperature profile of the segment along its height and the imposed strains and changes in crack widths as a function of time. The calculations take into account the stages of the occurrence of imposed and external loads and the resulting changes in the crack widths. The results obtained are also presented with reference to the currently applicable provisions of the current European standard. In addition, the authors point to those elements of the model from EN 1992-3 that should be analyzed at this stage to make possible amendments to the guidelines of the standard.
