After earning a BE in civil engineering with a structural specialty from the Lebanese university (Engineering department) and a research Master in geomechanics, civil engineering and risks from Grenoble Alpes university, I did a PhD thesis in 3SR laboratory (Grenoble Alpes university), in collaboration with CEA Saclay and Iffstar.
My research internship at 3SR dealt with the seismic study on RC structures. As for my PhD, the work focused on the modeling of concrete heterogeneities and their consequences on the mechanical behavior of concrete or Reinforced Concrete (RC) structures. During my PhD, I participated in different national and international conferences and published numerous articles in top-tier academic journals.
Since my PhD graduation in 2017, I worked at several universities in France and Lebanon as an assistant professor, which allowed me to teach different courses in several areas, especially in structural, material and soil areas and participate in the supervision of research projects. I have worked in Polytech Grenoble, City university and Angers university.
Since 2022, I was appointed as assistant professor in the civil engineering department in Balamand university. Due to the structural background of my studies, I was assigned undergraduate and graduate courses focusing on the design of reinforced concrete buildings (Etabs and shop drawing) and the finite element modelling of different concrete and reinforced concrete structures.
Research Interest
The research work focus on the modeling of concrete heterogeneities and their consequences on the mechanical behavior of concrete or Reinforced Concrete (RC) structures. These heterogeneities lead to the spatial variability of the concrete tensile strength at different scales. Thus, the influence of this spatial variability on the mechanical behavior and concrete cracking pattern is particularly enhanced using a Stochastic Finite Element (SFE) method accounting for statistical size effect.
The methodology used can be summarized, then, into two tasks:
• The estimation of the mean, dispersion and distribution of the tensile strength at
first crack, for structures of different sizes.
• The propagation of the variability on the tensile strength in Finite Elements (FE)
models.
A direct application of these approaches is currently done in the university of Balamand using the experimental tests performed in the laboratory on reinforced concrete beams subjected to 4-point bending load. Different concrete mix are being tested.
