Abstract: The number of degrees of freedom for the stability analysis of plane frames may be considerably reduced by introducing axial constraints. Determination of the rank and basis of the constraint matrix by Gauss-Jordan elimination ...

Abstract: In this study, the dynamic stiffness method is employed for the free vibration analysis of helical springs. This work gives the exact solutions for the natural frequencies of helical beams ...

Abstract: This paper concerns the formulation of a new element-based method for the static behavior of a spatial bar, with variable cross section of an elastic and isotropic material, under arbitrary loads. Using only one element ...

Abstract: This work gives the exact solutions for the coupled flexural-torsional buckling loads of variable and open cross-section columns, loaded by variable axial force. Both the cross-section dimensions and the axial load can ...

Abstract: Two methods for the solution of beams on variable two‐parameter elastic foundation are presented. The first is based on using the exact shape functions for beams on variable two‐parameter foundation, in order to obtain the ...

Abstract: The number of degrees of freedom for the dynamic analysis of plane and space frames may be considerably reduced by introducing axial constraints. Determination of the rank and basis of the constraint matrix by Gauss‐Jordan ...
