Stability of rigid frames with nonuniform members
Buckling capacities of rigid frames with nonuniform members are analyzed by numerical method using divided segments; fundamental and higher buckling loads and modes result from eigenvalues and eigenvectors of matrix which is product of sidesway flexibility and second-order stiffness matrix; sidesway flexibility matrix is obtained directly from shape of rigid frame and elastic properties of segments; second-order stiffness matrix is defined by axial forces in segments; method is approximate in that flexural stiffness coefficients of segments are those for uniform sections and without axial forces; computer and numerical examples are included.
