| Summary |
If a double-layer membrane structure has an enclosing space of which the air tightness is high， deformation in the inside membrane is induced due to the deformation of outside membrane caused by wind pressure， The authors named this phenomenon “drumming" and analyzed this phenomenon. The analysis method is an approximate one which simplifies the outside and inside membranes as band-shaped membranes and considers the inner space as that of adiabatic change. From the analytical results， it was understood that the stress in the inside membrane could reach very near to stress in outside membrane when the air permeability of the the inner space is zero. When the permeability increase with the existence of openings， the stress in the inside membrane decreases dramatically.
