((Estimate the Reliability of FRP Reinforced Concrete Slabs Subject to Significant Permanent Loads Using Finite Element Method))

Today, Sunday, 5/21/2023, at 9 Am in Ibn Al-Haytham Hall

The thesis submitted by the student aims to:

- Estimating the reliability of concrete slabs reinforced with polymer bars and comparing them with slabs reinforced with steel bars

-Study of many factors that affect the behavior of concrete under high-level stresses in the long term

The discussion committee consisted of:

-Prof. Dr. Amer Muhammad Ibrahim,               Chairman

-Prof. Dr. Shilan Mahmoud Hama,                     member

- Dr. Muhannad Haqqi Ismail,                             member

-Prof. Dr. Akram Shaker Mahmoud,                  member and supervisor

The master thesis included:

- Creating a number of models of concrete slabs reinforced with iron or polymer bars

-Comparing the experiemntal results with the results of the ANSYS program and noting the extent of compatibility between them by comparing the load and deflection diagram in the case of short-term loading and comparing the deflection curve with time in the case of long-term loading.

- Studying many factors that have an impact, such as the ratio of reinforcement, type of material of the reinforcing bars, compressive strength, and the ratio of the length of the bars to their thickness, and knowing the extent of their effect on the properties of reinforced concrete.

Results :

The study showed great agreement between the experimental and analytical results using the ANSES program, as the effect of all factors appears during short-term loading, while it does not appear during long-term loading in some factors, such as the effect of the type of reinforcement material and the effect of the reinforcement ratio.

- Reasonable reliability was found using code equations for long-term design, and the reliability index (beta) is constant for all previously studied models.

- ANSYS results are more reliable than theoretical results

discussion was attended by the Head of the Civil Engineering Department and a number of professors and graduate students in the department

congratulations to the student for obtaining her degree. We wish her the completion of her academic journey...and the discussion committee’s success and academic advancement.
