Current Research Interests
Advances in the Civil Engineering scientific field evolved very fast the last four decades due to the use of numerical methods in an attempt to accurately model and analyze the behavior of our structures. This ability was provided mainly through the use of the Finite Element Method which is considered to be one of the most important discoveries of the 20th century. Furthermore, the development of new materials such as fibre reinforced polymers and their use in our structures increased the demand of numerically and experimentally investigating the mechanical behavior of our structures. Therefore, developing new design formulae through the use of state-of-the-art modeling is now a modern reality.
One of the main objectives of the research work performed and presented in the list below, aims towards the improvement of our build environment through the development of accurate algorithmic implementations that will provide objective and computationally efficient numerical models in order to develop safer structures and designs. Developing high performance and accurate algorithms that will provide the ability to study the mechanical behavior of our structures under ultimate limit state conditions, will allow the scientific community to derive answers and propose improved design methodologies for earthquake resistant structures or structures that use emerging materials. Furthermore, this technology can be used to assess the carrying capacity of existing structures thus providing us with the necessary tools in obtaining numerical results that will be computationally accurate and objective.
Since he was introduced for the first time to the “research world” (Sep. 2003), Dr. Markou managed to get involved in different scientific fields and work with numerous scientists from around the world. The list of his research interests is provided below:
- Modeling of Reinforced Concrete (RC) structures through the use of 3D detailed finite elements.
- Mesh generation techniques of embedded rebar elements for the modeling of reinforcement inside reinforced concrete structures.
- Mesh generation techniques of embedded rebar elements for large scale-models.
- Hybrid modeling (HYMOD) of structures.
- Seismic assessment of reinforced concrete bridges through the use 3D detailed modeling and push over analyses.
- Programming and software development of Finite Element Analysis algorithms.
- Fiber reinforced polymer (FRP) modeling through the use of FEM.
- Soil-Structure Interaction modeling and analysis with 3D detailed FE and HYMOD. Static monotonic, static cyclic and dynamic analyses.
- Seismic assessment of reinforced concrete bridges through the use 3D detailed modeling and push over analyses.
- 3D detailed modeling of A-C-GFRP deep beams.
- Accurate and efficient modeling of the cyclic behavior of RC structures.
- Development of design formulae for FRP reinforced concrete deep beams through the use of experimental and numerical investigations.
- Mesh decomposition methods and parallel solution algorithmic development.
- Large-Scale Dynamic Analysis of structures through 3D detailed FEM simulations.
- Modeling and design of retrofitted RC structures.
- Artificial Intelligence and Machine Learning in Civil Engineering.
- Dynamic Mesh updating techniques for solving fluid-structure interaction problems.
Research Goals and Objectives
It is undeniable that our world is heading towards a CAD-based design era that will one day utilize our engineers with the ability to enter the minimum required data within a software, whereas the corresponding software will provide within a few seconds the technical drawings, the environmental report, the cost estimation and the technical specifications that will make the under study structure a high quality product for the consumer. In addition to that, the development of software applications that will be able to assess any type of design that foresee the use of new immersed materials will also be something common in the not so far future. Finally, the assessment of the capacity of existing buildings through non-destructive tests and state-of-the-art nonlinear static/dynamic modeling is a research goal that will provide engineers with the ability to propose retrofitting techniques, technical interventions and form strategies towards developing a safer environment for our society.
Mastering these research challenges is of great importance and form some of the main research objectives of Dr. Markou’s work. Towards achieving these goals, the development of a strong international research team that will extend and enhance the pre-mentioned research work (M.Sc., PhD students, Post Docs and Research Assistants) has been the task of the last two years.

The initial idea that led to the creation of ReConAn v1.0 Finite Element Analysis Program was to provide an Analysis Tool for Reinforced Concrete Structures, a program that would use state of the art Finite Element Technology combined with Computational Advanced Arithmetic Analysis methods. ReConAn v2.0 is now available and supports both 32 bit and 64 bit operating windows systems. The next version (v3.0) will be released soon and will integrate the latest developments such as dynamic analysis, FRP material models and other.
ReConAn is a general FEA program that is able to use several Finite Elements, Material Models and Solution Procedure. In addition to that, ReConAn has the ability to combine any Finite Element in a single FEM model, through kinematic compatibility equations.
It is well known that every FEA program consists of three different parts. The first and the third parts are those that deal with the visualization of the FE model and the results that the second part produces. For the creation and the visual representation of the FEA models, an interface was developed that gives ReConAn the ability to read all required FEA information from a neutral text type file that Femap v9.0+ produces.
Femap provides comprehensive functionality in an independent environment for modeling, simulation and review of product performance results. Geometry creation; Import or export of several file types; Meshing; User interface; Results; API.
ReConAn uses two post-processing programs. The first one is Femap, which provides all necessary post-processing tools that a FEA code should have, such as stress and strain contouring, virtual animation etc. The second post-processing program is ReConAn Eye which is encapsulated inside ReConAn main code structure. ReConAn Eye is based on pre-build OpenGL libraries f90gl. The need for the creation of a second post-processor lied within the inability of Femap to illustrate discontinuities (cracks). One of the material models that ReConAn includes in its material libraries, is that of the 3D smeared crack material model. The smeared crack approach gives the arithmetic ability of modeling materials that are dominated by crack phenomena such as concrete. Due to the fact that Femap cannot illustrate 3D cracks at a Finite Elements gauss point, the development of a visual tool that could do so was necessary. ReConAn Eye has the ability of 3D crack visualization in addition to its basic abilities (3D graphical FE model illustration, deformations - animation).
The generic code of ReConAn is written in the latest Fortran programming language and the development was done with the use of Microsoft Visual Studio.

This software provides the user with the predictive tool for computing the fundamental period of reinforced concrete structures with bare frames. The predictive model was trained to account for the geometry of the frame, the presence of shear walls, and the soil material properties. Therefore, the ability to account for the soil-structure interaction phenomenon is also available. The training was performed through the use of machine learning algorithms on a dataset that was generated through the use of Reconan FEA and 3D detailed modeling.
