%K beams of changeable rigidity, loading with temperature, &#-1279;nite-difference method
%X The paper presents solutions of beams with changeable rigidity. The &#-1279;nite-difference method was used for calculations. The way of construction of matrixes of displaced equation systems was presented. A solution for several static schemes of changeable rigidity beams loaded with mass and temperature gradient between bottom and upper plane of beams was given. Matrixes with their coef&#-1279;cients of general designations make it possible to get solutions for beams of the same static schemes but different rigidities.
