Development of engineering approach to Ultimate strength and stability analyses Of EC shells using the limit equilibrium method

摘要

Geometrically nonlinear theory of limit equilibrium allows to solve many problems of ultimate strength and stability analyses of RC (reinforced concrete) shells, considering process of shell deformating after transition into a plastic state. In brought below examples of the solution of specific problems of analyses of RC shells under various loads and boundary conditions is shown, that during analysis it is possible to define a Deformed state of an elastic-plastic shells to the moment on reaching the limit state and to Obtain the values of bearing capacity of RC shells corresponding with accepted scheme of Deforming.
