Stiffness Matrix for Buckling Analysis of Tapered Steel Members

Web tapered members are vastly used for steel structures. However, calculating their critical buckling loads involves applying numerical integration or charts or complicated equations. In an attempt to develop a simple, yet an accurate, solution for this problem, a closed form stiffness matrix for buckling analysis of web tapered steel member is proposed, which could be applied to a wide range of tapered steel structures. Moreover, with the advance in steel member design using "Direct Analysis Method", the critical buckling load of a column is considered with an effective buckling length equal to its unbraced length. Applying the closed form stiffness matrix, developed in this research, yields the critical buckling load for a column with any boundary conditions. Verification examples are provided to illustrate the accuracy of the procedures.
