Splet28. jul. 2024 · Figure 5.3. 1: Trusses are made entirely of two-force members. This means that each member will either be in tension or compression, as shown here. Trusses can be broken down further into plane trusses and space trusses. A plane truss is a truss where all members lie in a single plane. This means that plane trusses can essentially be treated … 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.
SpletFigure 9.1: Degrees of Freedom. Since there are only rotational DOFs in this structure, and no translational DOFs (i.e. all nodes remain at the same points in space), then this top structure shown in Figure 9.1 is considered to be a non-sway frame. In contrast, a sway frame is a structure where any of the joints can translate or displace.
