| Summary: |
| This paper presents the procedure for stability analysis of frame structures in elasto-plastic domain. This analysis is performed using the code ALIN, developed in the C++ programming language. In this code the stiffness matrix is derived using interpolation functions related to the exact solution of the differential equation of bending of a beam according to the second-order theory. Also, the concept of tangent modulus is applied for the stability calculation in the inelastic domain. |
