The conjugate frame analogy is extended to the treatment of continuous space frames. Fundamental relationships between the actual structure and the conjugate structure are derived for a general case, and then specialized for frames with straight members of constant cross-section. The latter are used for the derivation of simultaneous equations which, in conjunction with the static equilibrium conditions, yield the redundant quantities.

A simple technique for writing the elastic equations for rectangular grids, based on the equation of virtual work, is presented.
Reinforced concrete structural members subjected to direct and bending stresses are in common use. The design of such members as columns with eccentric loading, arch sections and rigid frames involves the solution of cumbersome cubic and higher degree
equations. A graphical method suggested below gives a simple and rapid solution.
