Användbarheten av Beam EC2 inom betongelement : En jämförelsestudie mellan beräkningsprogrammen Beam EC2 och Concrete Beam

Concrete is a versatile building material used all over the world. Today's constructions in building and civil engineering have high requirements and complexity that require a carefully executed dimensioning in connection with planning. Calculation programs that work based on standards are a tool for designers in calculation work. Complicated programs or ambiguities in the programs can take up important time, therefore good and clear programs are necessary for time efficiency. This thesis has compared the calculation programs Concrete Beam and Beam EC2, which both are calculation programs used for dimensioning concrete beams. Concrete Beam is used by most constructors in Sweden, while Beam EC2 is a new calculation program that is not used to the same extent. There is therefore a need to evaluate the respective calculation programs in order to increase knowledge in the construction industry about the differences between the calculation programs, as well as to open up the possibility of using more calculation programs in the future. The aim of the thesis is to investigate whether there are differences between Concrete Beam and Beam EC2 when dimensioning a concrete beam. To implement this, the differences in factors such as ease of use, available functions and a calculation result are examined. A smaller sensitivity analysis is also performed to analyze the stability of the calculation programs' values. The thesis is carried out as a case study with input from a completed reference project by Sweco Sverige AB. The reference project contributes realistic values ​​that are used as input data in the study. The values ​​from the reference project are supplemented with smaller hand calculations for the loads acting on the beam, for example the dead weight and the wind load. This is because values ​​from the reference project are missing. The implementation involves applying the specified values ​​for the inputs from the case study and the hand calculations in the program
