Stability and load bearing capacity of a truss with elastic braces

摘要

The present paper is devoted to the numerical and experimental investigations of stability of a truss stiffened by elastic braces. The model of a real roof truss scaled by factor?was investigated. In the research the linear buckling and non-linear static analysis of the truss shell and beam model with geometric and material non-linearity is presented. The initial imperfections were assumed in the form of the first buckling mode. As a results the buckling and limit load was found related to the truss bracing stiffness and the threshold bracing condition was obtained necessary to provide maximum buckling resistance of the truss.
