A single layer latticed shell of two force members is the sort of pure discrete system that appears best suited for a micro field approach. Although such systems are in popular use, their analysis by rational field methods is not well developed; thus, the coverage here is introductory in nature. The object of this section is the statics analysis for the member forces in a latticed shell or curved truss work whose geometry is such that a projection of its nodes on a plane form on evenly spaced pattern of points suitable for description by Cartesian coordinates (but not necessarily orthogonal). That is, the members running in the two coordinate directions and in the diagonal direction from x,y to x + 1, y + 1 (see Fig. 9). Here the discrete coordinates will be labeled x and y to conform with existing publications.
