Abstract: The capacity of columns can be increased by using crossarms and pretensioned stays. It is shown that the buckling load of a single crossarm stayed column is a function of the stiffness of the stays, and the ability to ...

Abstract: The elastic and inelastic buckling of cruciform section columns formed from four equal leg angles is examined. The elastic critical loads for flexural, torsional and plate building are determined. Two different and extreme ...

Abstract: The nonlinear behavior of space truss members is described and modeled. The interaction between a space truss member and its adjoining structure is detailed and the “Chordal Snap Through” phenomenon is described. A nonlinear ...

Abstract: Results are presented from an investigation on stiffening wideflange steel beams for torsional loading. Four types of stiffeners, involving either plate elements or small sections of channels, were used for pin ended, fix ...
