By analogy with the previous chapter, the analytical procedure of an approximate analysis of roofs on the circular plan is based on the membrane theory of depressed shells and is put into efect depending on the dimensionless parameter [bar.S] = 0,125qR / Et, relative longitudinal rigidity of the boundary support [bar.k] = [(EA).sub.k] / EtR and coefcient [beta], which specifes the surface form (Trofmov, Yeremeyev 1990).
