Structural Analysis
Elastic Flexural Buckling of Columns
A member subjected to pure compression, such as a column, can fail under axial load in either of two modes. One
Elastic Lateral Buckling of Beams
Bending of the beam shown in Fig. 3.90a produces compressive stresses within the upper portion of the beam cross section and
Elastic Flexural Buckling of Frames
In Arts. 3.41 and 3.42, elastic instabilities of isolated columns and beams are discussed. Most structural members, however, are part
Effects of Welding
Failures in service rarely, if ever, occur in properly made welds of adequate design. If a fracture occurs, it is
Effects of Grain Size
As indicated in Fig. 1.14, when a low-carbon steel is heated above the A1 temperature line, austenite, a solid solution of
Effects of Chemistry on Steel Properties
Chemical composition determines many characteristics of steels important in construction applications. Some of the chemicals present in commercial steels are a
Effects of Punching Holes and Shearing
Excessive cold working of exposed edges of structural-steel members can cause and cracking and should be avoided. Punching holes and
Effects of Thermal Cutting
Fabrication of steel structures usually requires cutting of components by thermal cutting processes such as oxyfuel, air carbon arc, and
