Element Approach

A new finite element approach described in this paper uses an equivalent plane rectangular truss element to replace the traditional plane rectangular element in the nonlinear analysis of reinforced concrete structures. The major advantage of this approach is the simplified finite element model with reduced degrees of freedom and without the need of using displacement functions. The new approach can also trace the formation, development, and location of cracks in the reinforced concrete structures. The results of numerical analyses of structural examples showed that this new approach gave satisfactory results to the engineering problems in comparison with those obtained using the more complicated FE package ANSYS8.0.

The author has created a new technology for concrete beam, column, slab, wall and shell reinforcement computation according to the finite element program COSMOS/M analysis results and code of practice valid in Lithuania. A brief description of the technology is included in the article. Computer programmes COSARM and COSMAX were designed for slab, wall and shell reinforcement computation. Results can be visualized graphically. New computer programmes BEAM, COSBEAM, COLUMN, COSREC and COSCIR were created for beam and column reinforcement computation. The new technology extremely enlarged the possibilities of the powerful finite element program COSMOS/M and enabled to compute very complicated reinforced concrete structures.
