Research Activities

            Research by the faculty is carried out in three distinct groups of Structural Engineering, Water and Environmental Engineering, and Geotechnical and Highway Engineering.

 

 Structural Engineering

            The three major themes addressed by the research groups in our department are including: Applied Mechanics, Reinforced Concrete Technology and Numerical Methods.

            The group of applied mechanics is currently engaged with the following research:

 -   Free-vibration analysis of tanks containing more than one liquid

 -   Investigation of the elastic and plastic behavior of encased castellated I-beams

 -   Solution of triangular plates having variable thickness and different boundary conditions

-   Local, distortional, lateral and post buckling of curved beams, composite structures and                 moving plate

 -   Investigation of strength of masonry columns under axial loads.

The vast use of Reinforced Concrete (RC) structures all over the country and the need to revision of Iranian Concrete Code necessitate novel research works in prestigious universities of the country. On the other side, the essential changes in traditional concepts of Concrete Technology and emerge of new materials and admixtures in concrete mixes have created attractive fields of research all over the world. These are good reasons to attract the professors and the graduate students (Master and Ph.D.) of the Department of Civil Engineering to focus on the aforementioned subjects; both experimentally and theoretically. Some of the current research subjects being conducted in the structural and material laboratory of the department are as follows:

-   Ductility and moment redistribution in continuous RC beams and frames

-   Flexural, shear, and tortional strengthening of RC beams and frames with Fiber Reinforced Polymers (FRP)

-   Debonding phenomenon in FRP strengthened RC members

-   Surface preparation and its effect on debonding of FRP composites from concrete beams

-   Novel substitute methods to surface preparation to postpone debonding of FRP sheets from concrete substrate

-   Mechanical and durability properties of High Strength Concrete (HSC) and High Performance Concrete (HPC)

-   Mechanical and physical properties of Fiber Reinforced Concrete (FRC)

-   Mechanical and rheological properties of Self Compacting Concrete (SCC)  

-   Novel procedures for mix design of HSC, SCC and FRC

Numerical simulation of engineering problems involving studies on mesh-based and mesh-less methods.  In the mash-based part, mainly focusing on finite element method, the studies are performed on error estimation and adaptivity, continua with incompressibility behavior, topology optimization of structures, discrete Green’s functions and wave propagation in domains with periodic material properties (with application to problems with multi-scale features).  In the mesh-less part, the studies are conducted on the Finite Point Method as well as a new boundary collocation method using fundamental exponential bases.
