The Strains in multi-ply fully bonded membranes were analyzed being based on the theory of elasticity, and a simultaneous differential equation was obtained in the previous paper. This paper is in advance of the previous one and deals with strains in multi-ply membranes in the following cases; (1) fully bonded membranes are partly ruptured, and (2) membranes are partly loose laid over the joint of substrate. Partly ruptured membranes such as the former case are sometimes discovered in actual roofs, and the differential equation in the previous paper can be applied in this case except the boundary conditions at the joint of substrate. The method of partly loose laying membranes over the joint of substrate, as the latter case, is often used in roofs constructed with prefabricated roof planks. In this case, a new differential equation is obtaind for strains in loosed membranes, and the equation in the previous paper can be also applied for fully bonded membranes. Both equations are combined with boundary and series conditions, then all integral constants are determined and strains induced in each membrane can be obtained.
