In Chapters 1 and 2 consideration was given to the structural analysis of beams and in Chapter 3 to the analysis of plane frames with loads applied in the plane of the frame. When the plane structural frame is subjected to loads applied normally to its plane, the structure is referred to as a grid frame. This structure can also be treated as a special case of the three-dimensional frame that will be presented in Chapter 5. Plane frames and grid frames are treated as special cases because there is an immediate reduction of unknown nodal coordinates for an element of the frame.
