The span therefore represents phase of partial continuity from that of the previousproblem. The principle here involved is employed in the 272 THEORY OF FRAMED STRUCTURES Chap. VI design of a bascule span composed of two leaves connected by ashear lock. The principle must be modified, however, in itsapplication to a bascule span; for the leaves do not as a rulehave a constant moment of inertia, nor are they in perfectrestraint at the points of support. A constant moment of inertia and perfect restraint will beassumed in finding the shear V on the pin-connection at C,. I x-OkJl-x-- -hi
