Short introduction to the programme package TULISA

This paper presents briefly the programme package TULISA as used for the static, linear and non-linear, elastic and elasto-visco-plastic analysis of the stress and strain state in the soil and around underground openings. The programme package TULISA has been developed as a combination of the previously developed programmes CUGRAV and BETHEV. This programme includes, from the CUGRAV programme, a model for the soil which is treated as a homogeneous material, wherein an adequate spatail discretization can be performed by means of mapped infinite elements, so that it is possible to perform the modelling of the influence of the surrounding infinite space. The part taken over from the BETHEV programme includes a very simple model for the concrete which is used to simulate its non-linear behaviour together with the reinforcement. The whole package is still being developed. A simple example from everyday engineering practice is given to illustrate some possibilities of the new programme package TULISA application.
