Lateral torsional buckling analysis of truss-braced timber arches

Abstract Buckling analysis of arches is an important issue of the design of timber structures containing such structural elements. In the article an analytical and an approximate solution is proposed for lateral torsional buckling analysis of truss-braced timber arches. Application of the proposed m...
