Strain-stressed state of reinforced concrete containment shell of NPPs with prestressed reinforcement beams

A technique is developed for PC computation of the cladding; it allows to perform a sufficiently reliable and fast assessment if the strain-stressed state (SSS) of a structure in the process of reinforcement beam prestressing. ASTAN-PUCHOK software package for IBM PC/AT is developed. The package is intended for calculating intricate thin-wall structures manufactured in the form of rigidly-jointed fragments of round plates and shells of revolution, taking into account arbitrary changing in the plane and meridian loads. Shell fragments can be uniform and reinforced. The method of load expansion into Fourier's Seria by the angular coordinate and the method of finite element are used in calculations
