It is well known that the continuum model of a shear wall is a sandwich beam which consists of 'stiff' and 'soft' layers. The paper presents the differential equation system of the multi-layer sandwich beam, and gives a method and closed formulas to determine the critical load in case of a concentrated force acting on the top of the beam. The paper also shows that the critical load of a multi-layer sandwich cantilever is - to a close approximation - equal to the critical load of a triple-layer sandwich beam, i. e. a sandwich with thick faces.
