The Influence of Variable Cross-Section of System Modeling Mining Support Structure on the Value of Critical Load under Active and Passive Specific Load

The Influence of Variable Cross-Section of System Modeling Mining Support Structure on the Value of Critical Load under Active and Passive Specific Load

SZMIDLA Janusz, JURCZYŃSKA Anna

Abstract. Theoretical considerations and results of numerical computations regarding a slender column modeling mining supporting structure were presented in this paper. The system was subjected to a selected case of a specific load (follower force directed towards the positive pole), active and passive. The numerical simulations presented in this article refer to the influence of a cross-section variable along the axis and the geometry of a structure implementing an external load on the value of critical force.
