Özet:

 

An approximated model and mathematical formulation are  presented for the uniform torsion analysis of closed moderately  thick-walled, thick-walled, and solid cross-sections.  For this  purpose, the considered section is ideally divided into thin-walled  closed strips one inside the other.  Using this model and Bredt's  theory, the torsional moments carried by each strip are obtained.  Then, considering that the number of the imaginary strips is  sufficiently high, formulas are derived for the maximum shearing  stress and the angle of twist of the considered cross-section.  To  demonstrate the accuracy and efficiency of the formulation, results  for several cross-sections having exact or numerical solutions are  presented.  These results show that the formulation gives accurate  values for solid and hollow sections with regular curvilinear  contours.  On the other hand, although for the thin-walled and  moderately thick-walled sections there is high accuracy in the  results, for the thick-walled and solid ones the accuracy decreases  gradually.  Thus, it is thought that the derived formulas can be  useful especially for the analysis of a wide class of closed  thin-walled and moderately thick-walled cross-sections subjected to  torsional loading.
