Analysis of Creep in Reinforced Concrete Beams Using Eurocode

This technical report presents an analysis of the creep behavior of reinforced concrete beams in accordance with Eurocode 2, utilizing a three-parameter rheological model. The study aims to assess the effects of creep on structural performance through numerical modeling of two beam configurations: a simply supported beam and a cantilevered beam. The report begins with a basic literature review on creep, defining it as the progressive increase in strain under constant loads, influenced by factors such as humidity, temperature, and concrete composition. The analysis employs the European Standard EN 1992-1-1 to calculate the creep coefficient and compares it with results obtained from the three-parameter model. Detailed equations and methodologies are provided for calculating deflections and strains over time, considering both models. The findings illustrate how creep affects deflections and stress distributions within the beams, highlighting the importance of accurately modeling this phenomenon for structural integrity and safety.
