ANALYSIS OF STRUCTURES IN THE FORM OF A SHALLOW RETICULATED HYPERBOLIC PARABOLOID WITH ACCOUNT OF GEOMETRICAL NONLINEARITY

Cover Page

Abstract


Numerical procedures for nonlinear analysis of flexible reticulated shells in the form of hyperbolic paraboloid are proposed. Geometrical relationships with account of large displacements and shear deformations are used. The discrete model of shell is reduced to continual model with effective rigidities. The finite difference energy method and continuation method are used for analysis of shallow reticulated shells in the form of hyperbolic paraboloid with different types of boundary conditions
