The FE model, calibrated and validated against the experiments, was used to perform a parametric study over a wide range of section slenderness.
Trish Hall, a long-time writer and editor who has led a wide range of sections at The New York Times, was promoted on Friday to assistant managing editor for features.
Upon validation of the finite element models, parametric studies were performed to assess the structural response of HSS sections over a wider range of cross-section slenderness, cross-section aspect ratio and moment gradient.
The models were first validated against the experimental results after which parametric studies were performed to generate data for a wider range of cross-sections.
The parametric studies were carried out to generate additional structural performance data over a wider range of cross-section aspect ratios and slendernesses, loading combinations and bending orientations.
In addition, extensive parametric analyses of similar columns, but with a wider range of cross-sections, subjected to pure torsion were carried out using the SOFiSTiK software.
The test results were employed in a parallel numerical simulation programme for the validation of finite element (FE) models, by means of which a series of parametric studies were carried out to extend the available results over a wider range of cross-section sizes, member lengths and loading combinations.
A parametric study is carried out with various section sizes, lengths and concrete strength in order to cover a wider range of member cross-sections and slenderness which is currently used in practices to examine the important structural behaviour and design parameters, such as column imperfection, non-dimension slenderness and buckling reduction factor, etc.
Instead, it is offering a wider range of prices within each section, with some seats becoming more affordable and others more expensive.
