Sway frame truss
SpletFrames are classified as sway or non-sway. A sway frame allows a lateral or sideward movement, while a non-sway frame does not allow movement in the horizontal direction. The lateral movement of the sway frames are accounted for in their analysis. Frames can also be classified as rigid or flexible. SpletBefore defining sway frames and non-sway frames, it is useful to note the common design practice for evaluating safety of structures against stability. It is often convenient to …

As a structural system, the strength of the space frame truss system is typically developed in parallel series of planes between columns, following civil engineering practice, called “bents.” Each bent is a ...
SpletRoof Truss Design. Architectural style, types of roofing material, methods of support of column framing, and relative economy are the principal factors influencing a choice among the three basic types of trusses: bowstring, pitched, and flat. In addition, side- and end-wall height and type, roof shape, and bracing requirements must be considered.
SpletThe sway produces relative lateral displacement of the ends of some of the frame members, which causes moments in addition to those due to joint rotations. The final moments are obtained by superposition, as shown in Figure 7.22, the magnitude of the sway being obtained from equations of static equilibrium known as the sway equations. merge header cells in pagesSpletframe shown in Fig. 4 to support 750 kips, using A36 steel (Fy = 36 ksi).
