Types of Structures Framed structures: Plane trusses: Composed of straight members connected at their ends by flexible connections. Subjected to loads and reactions only at the joints (connections). Members of a plane truss are subjected to only axial forces . Plane frames: Composed of straight members connected at their ends by rigid (moment resisting) or flexible connections . Subjected to loads at the joints and on the members . Members of a plane frame may be subjected to bending moments, shears, and axial forces . Space trusses Space frames Surface structures: (CEE 232) Plates Shells 4
