Summary: A program for the nonlinear nonlocal numerical analysis of space problems by the finite element method, using a microplane model for brittle-plastic material concrete is to be worked out. The programme should involve both monotonous and cyclic static loading as well as the creep effect. The problem of slab and column punching for a flat slab structural model is to be analysed by this programme. The structure is loaded by a vertical force and by bending moment ap to failure. The results obtained by this numerical analysis are to be compared with the results of model tests known in the world.

Keywords: Constitutive relations, Microplane model, Nonlinear, Nonlocal, Monotonic, Cyclic, Viskosity, Creep, Concrete, Softening, Hardening

Research goals: The aim of the project is to work out a programme for the nonlinear nonlocal numerical analysis for space problems by the finite element method in which the microplane model for the brittle and plastic concrete will be used. The programme will include static loading, both monotonous and cyclic, as well as the possibility of loading the structure by given displacements. This programme will be used to analyse the problem of slab and column punching for the flat slab structural system. The results obtained by this numerical analysis will be compared with the results of the model analysis of an identical structural system by the authors A.A.Elgary and A.Ghali, published in ACI Structural Journal September-October 1987. The results of the analysis will be presented at professional congresses and published in journals both in our country and abrood.
