... and provide lateral bracing for supporting steel framing. A typical method of attachment is a field-welded connection between the supporting steel and steel embedments in the precast planks. 8.3 ... Many panels can achieve a fire rating when used as part of an approved ceiling assembly. The panels are typically attached to steel framing with cold-formed -steel clips (see Fig. 8.12)....

... external force and reaction on that part of the truss; i.e., all forces acting on the free body must satisfy the three equations of equilibrium [Eq. (3.11)]. For three-dimensional structures, the equations ... For some structures, however, such changes in dimensions may not be negligible. In these cases, the equations of equilibrium should be defined according to the deformed geometry of the...
