Tiivistelmä
The thesis was commissioned by an engineering company, to develop alternatives and best practice for peak value management when analyzing concrete slab structures with FEM design software. The purpose of the thesis was to find out various factors affecting the modelling of the reinforced concrete slab and its dimensioning, and to solve the singularity problems that affect the dimensioning of the reinforced concrete slab. The aim of the thesis was to create a clear and easy-to-read guideline for the modelling of reinforced concrete slabs, focusing on the management of singularity values.
The thesis consists of a theoretical part, which explores acceptable ways to deal with singularity values management, and a calculation part, where different approaches to the problem are tested using the FEM model and Excel calculations,and compare the results obtained between these two.
The result of the thesis, the guideline for optimized concrete design taking into account the management of singularity values, is a confidential annex. The public part of the thesis takes a stand on the correct FEM modelling of the reinforced concrete slab and gives an insight on how to analyze singularity values when designing a reinforced concrete slab.
