The initial boundary-value problem on the heat conduction 
in shells reinforced with fibers of constant cross section has been 
considered. It has been established that the specific, anisotropic, 
inhomogeneous properties of such a shell are determined by its heat 
conductivity dependent on the thermophysical properties of the phases 
of the composite material of the shell, the parameters of its reinforcement, 
and the geometry of this shell. The ways of reducing the three-dimensional 
problem on heat conduction to the two-dimensional one and the possibilities 
of reducing the dimension of this problem for thin shells of revolution 
reinforced symmetrically relative to their axis by two units have 
been determined. The stationary temperature fields of concrete thin 
shells of revolution with different Gaussian curvatures and different 
reinforcement structures have been compared. It is shown that the 
reinforcement structure and the geometry of a shell of revolution 
substantially influence the temperature distribution in this shell, 
which opens up a wide range of ways selecting designs of such shells 
with improved thermophysical parameters.
