Popis: The lateral-torsional buckling occurs in a beam when the beam's unsupported length is greater. The beam will fail by lateral-torsional buckling when the compression flange is free to rotate and displace laterally. The lateral stability of the I-section is an important factor in the design of pre-engineered buildings. The design to resist the bending and twisting in the frame I-section that is rafter and column in lateral direction flange bracing acts as a restraint to resist lateral-torsional buckling. The top flange is connected with purlins to act as a lateral restraint. The bottom flange torsional moment is resisted by flange bracing. Increasing the flange bracing decreases the unsupported length of the compression flange, so there is a decrease in lateral-torsional buckling. If the non-dimensional slenderness ratio ( λlt
