Nodal rotations are produced by bending and shear effects and bending rotations can be easily calculated using Euler?Bernoulli?s stiffness matrix method. Nevertheless, shear rotations are traditionally neglected, as their effects are practically negligib...

The high strength and stiffness-to-weight ratios of structural steel often result in relatively slender members and systems, which are governed to a great extent by stability limit states. However, predicting the stability of slender structures is diffic...
