Abstract
This paper presents a possibilities for increasing the
efficiency of non-linear analysis for reinforced concrete
beam structures by application of the finite element method
(FEM). A various procedures for discretization of the beam
structures are discussed. Special attention is paid to the two-dimensional
beam finite element (beam FE).
Opposite to standard approach (i.e. Finite Layer Technique - FLT), which means discrete change of material properties, proposed procedure suggest calculation of crosssection stiffness based on "continuous" change of material properties. If discretization is performed by a low number of layers, because of assumption of constant axial stress, in standard FLT, errors appear in approximation. Proposed procedure partially solve this problem. purchase the full-text of this paper (price £20)
