Solid sections are gradually replaced by the hollow in most of structural applications various engineering fields due to their attracting features such as light-weight and high specific strength. In present investigation, one attempt was made investigate detail about flexural capability an aluminum tube (AHT) with square cross section. The objective investigation is study influence stress conce...

Uncapped, hollow polymeric microstructures were fabricated on a silicon substrate using electric field induced stretching and detachment. Initially, square or cylinder microposts were generated using a solvent-assisted capillary molding technique, and a featureless electrode mask was positioned on the top of the microstructure with spacers maintaining an air gap (∼20 μm). Upon exposure to an ex...

Three models are established under the multivariate nonlinear regression analysis technology, and on the base of the existing and survey data, which are the double-lane road alignment safety evaluation model, the psychological reaction of driver safety evaluation model and the driving safety comprehensive evaluation model. Then, a quantitative evaluation of the experimental section is made by t...

Thin-walled hollow steel columns, either circular or box shaped, are commonly used as piers in bridges. Recent earthquakes, e.g. Hyogoken-Nanbu or Kobe 1995, on the other hand have shown that these columns are vulnerable to damage when subjected to earthquake loading. This paper presents a new innovative thin-walled hollow steel column fabricated of corrugated plates, “thin-walled steel columns...
