of the beam are analyzed by combining the theories for curved beam analysis and for the beam on elastic foundation analysis.The governing equation is derived for the radial displacement of the outer beam.With adequate boundary conditions this equation is solved analytically.The equivalent stiffness of...
The application of the standard virtual work expressions to the large displacement-small strain domain merely requires the replacement of the standard linear strain-displacement relations by the quadratic ones. In fact, the geometrical stiffness matrix of an arbitrary finite element can be derived immedi...

Matrix Structural Analysis" by J.S. Przemieniecki, pp 388-391, McGraw-Hill, 1968. His derivation is for a 2D beam (6 DOF), but is easily extended to 3D (12 DOF). I've successfully used this to determine beam buckling as well as the effect of end-loading on the lateral ...

A stiffness matrix for a beam element with shear effect on an elastic foundation is developed using the differential-equation approach for plane-frame analysis. Small-displacement theory and linear-elastic material are assumed. The contribution of the shear stresses to the deflection of the beam in...
The concept to increase the fundamental natural frequency (below which no vibration could occur) of a structure as high as possible is commonly adopted to make the structure better in dynamic environment. Due to design limitations, the fundamental frequency of a beam can be increased via adding ...
In general terms, the stiffness of a material is calculated by using the following equation: stiffness = Force displacement The Young’s modulus stress-strain curve shown above is a good way of graphically demonstrating stiffness. The ratio of stress to strain is the elastic modulus (stiffness...
The formation of thestiffness matrix[K] is the most crucial step in the matrix solution of any structural problem. We shall show in the subsequent work how thestiffness matrixfor a complete structure may be built up from a consideration of the stiffness of its individual elements. First, howev...
