Abstract
7190 Lateral torsional buckling of l-sections in grade 55 steel The introduction a new grade of higher yieldstrength steel into the British Standard of Specification for structural steels has created much demand for research on structural behaviour. To provide soundly based design data for laterally unsupported beams the theoriesdeveloped to date have been reviewed and extended to applyto steels of higher yield strength. As a further result the requirements of future work in this field have been highlighted and the basis and limits of existing theories explained. A series of tests on beams of universal I-section in DL30 steel undera uniform bending momentwascarriedout to verify theproposeddesignstresses... 7190 Lateral torsional buckling of l-sections in grade 55 steel The introduction a new grade of higher yieldstrength steel into the British Standard of Specification for structural steels has created much demand for research on structural behaviour.
