According to deformation features of pre-twisted bar, its elastic bending and torsion buckling equation is deduced. The equation indicates that the bending buckling deformations in two main bending directions are coupled with each other, and bending and twist buckling deformations are also coupled with each other because the cross-section shear center does not coincide with the shape center. However,...
With the extensive application of pre-twisted beam in engineer structure, it is very important to carry out systematic analytical research of pre-twisted beam, put forward a dependable mechanics analysis model and the calculation theories. The paper carries on mechanical property based on small deformation assumption to get the displacement general solution, and verify its accuracy using ANSYS software...
