Through the structural design of the industrial building in South Asia PU Factory, designers discuss the internal force analysis, selection of sections, design of panel joints, deformation computation and layout of the bracing steel truss with the corbel for cranes. Some problems on the structure are also discussed.
Keywords: steel truss; corbel; crane; deformation computation; secondary moment
