Members carrying both axial force and bending moment are subjected to an interaction between these effects. The analysis of a beamcolumn using stability functions as an alternative to the stress stiffness matrix is discussed. Explicit expressions for stability functions for threedimensional beamcolumns, in terms of member length, crosssectional properties, axial force, and the end moments, are derived. The effect of flexure on axial stiffness and the effect of axial force on flexural stiffness and stiffness against translation are considered in the derivation of stability functions. The effect of axial force on torsional stiffness and the effect of torsional moment on axial stiffness are neglected. The nonlinear stiffness matrix of a threedimensional beamcolumn using the stability functions is presented by modifying the linear elastic stiffness matrix for a beamcolumn which includes the effect of shear deformations available in the literature. A numerical example showing the calculation of stability functions for a given beamcolumn is also presented. |
