Simulation of flowsheet configuration was performed with ASPEN HYSYS™, using the two columns model.
Although we did not directly measure stress, based on the concept of the three column spine model [ 32], we propose that increased BMI may indirectly contribute to axial stress.
Because the tension leg platform is normally supported by four vertical columns, model experiments are carried out to study the diffraction of regular waves by a four-cylinder structure.
More encouragingly, the simulations successfully demonstrated the differences in performances of three columns without changing model parameters other than concentrations of nitrate in the influent.
In the next column (Model 1), the three indicators of adverse family psychosocial characteristics have been included in the same model.
For the 1-story frame model, paths A and C require only three column removals before collapse is initiated whereas path B involves the removal of four columns.
Two duplicate columns modeled sub-aerial tailings weathering alone, a third modeled the effects of long-term floodplain tailings contamination and a fourth modeled that of a tailings dam spill on a previously contaminated floodplain.
The parametric study was performed in two stages by considering two different sets of column models.
Two single-column models with different boundaries were shown to have low accuracy.
The explicit expression of resistance functions of the beam that are used in the SDOF model are obtained from a simplified nonlinear static analysis of two beam-column models.
