Thin walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses.. Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have
Dec 12, 2013 · The finish rolling temperature of the thin walled high strength H beam steel is in the range of 750 °C–850 °C. The lower the finish rolling temperature and the faster the cooling rate, the finer the ferrite grains, the volume fraction of bainite is increased through water cooling process.
significant effect on the ultimate strength of thin walled I section beam columns only when it is less than 75. Changing h w /t w between 75 and 150 reduced the ultimate strength by about 3%.
In general, the simple formulas proposed herein give a reasonably accurate estimate of the strength of the beam columns over a wide range of the steel yield stress, and for the most part, they are applicable to the thin walled box beam columns made from both mild and high strength steels.
1. Introduction. The local and overall instability problem is encountered in eccentrically loaded high strength thin walled rectangular concrete filled steel tubular (CFST) slender beam columns with large depth to thickness ratios.

This study proposed a prediction formula for the torsional strength enabling to reflect the tensile strength of ultra high performance concrete (UHPC) beams based upon the thin walled tube theory. The remarkable ductile behavior of UHPC can also be attributed to the steel fiber reinforcement. This feature must be considered to provide rational explanation of the torsional behavior of UHPC
1. Introduction. Aluminium thin walled beams are commonly used structural members in the automotive, aerospace and manufacturing industry. Besides conventional advantages like high stiffness and high strength to weight ratio, they are also capable of dissipating high amount of impact energy evenly in large deformation collapses.

Mar 01, 2009 · The ultimate strength and ductility of high strength thin walled concrete filled steel tubular (CFST) beam–columns with local buckling effects, are investigated in this paper, using a performance based analysis (PBA) technique. The PBA technique accounts for the effects of geometric imperfections, residual stresses, strain hardening, local buckling and concrete confinement on the
1. Introduction Thin walled members with open section are widely used in structures for their high ratio of strength to weight. The loading capacity of these structures is closely related to the overall and local stability of thin walled members, leading to the investigation of the elastic and inelastic buckling analysis of these members.
