In contrast, the accelerograms can be selected in such a way that the diagrams display softening behavior and the resulted collapse diagram show a high collapse probability.
Meshes that were dominated by buckling deformation showed relatively high collapse strength and were prone to exhibit brittle characteristics in their stress strain curves.
However, the high collapse casing (HCC) shows a higher resistance to collapse pressure so that it has obviously improved collapse properties in excess of API ratings.
Muramatsu (1963) pointed out the sharp changes in the vertical displacements around Gifu City, from uplift to subsidence, and the high collapse rate of houses along the Gifu-Ichinomiya line.
Hence, a new high collapse model with manufacturing imperfections, strength differential (SD) effect, yield-to-tensile strength ratio, material hardening and intermediate principal stress effect, which can predict the collapse strength of HCC, has been presented based on unified strength theory.
Numerical and experimental comparisons show that the calculation results of new high collapse model are much closer to the test data than that of API and ISO models, which will make great improvements in the casing design of deep and ultra-deep wells on the basis of HCC material safety.
