Jordan Eliminations in Force Analysis When Changing Beam Structural Design

Purpose: The aim of the work is to study changes in forces in cross sections of a statically indeterminate beam when changing the structural design. Methodology: Jordan elimination is used to solve the system of equations. Jordan elimination used in the force analysis is considered on the example of the formation of a statically indeterminate beam by connecting two previously calculated statically indeterminate beams into one. Research findings: The data obtained for two separate statically indeterminate beams and Jordan elimination allow to calculate the forces and displacements for a statically indeterminate beam obtained by connecting two separate beams without the need to solve a new system of resolving equations.
