Research at the Department of Civil Engineering
The faculty is actively involved in several multi-faceted research and consulting activities with high relevance to industry and society. The department has been at the forefront in areas such as Earthquake Engineering and Structural Dynamics, Geotechnical Engineering, Transportation Engineering, Fibre Reinforced Concrete, Prestressed Concrete, Geopolymer Concrete, Ground Water Hydrology, and Special Concretes. The notable among them are:
Earthquake Engineering and Structural Dynamics
Seismic isolation is emerging as a new trend in earthquake-resistant design with great potential for the future. A seismically isolated structure experiences reduced seismic forces and accelerations and moves essentially as a rigid body, preventing damage due to deformations. This is achieved by mounting the structure on horizontally flexible devices, known as seismic isolators, which make the structure move in a much slower and smoother fashion, avoiding resonance. Seismic energy imparted to the structure is substantially reduced or dissipated by the isolators, which are properly designed for such a purpose.
Advancements in Concrete Technology
Concrete is the single largest manufactured material in the world and accounts for more than 6 billion metric tons annually. Initial and life-cycle costs play a major role in today’s infrastructure development. There have been several notable advancements made in concrete technology in the last fifty years. Advances in concrete technology are concerned about the materials that are required for manufacturing concrete; workability, proportioning, mechanical properties, and durability properties of concrete; and various tests on concrete. The latest developments are aimed at the use of recycled materials in concrete for sustainability and design a concrete mix suitable for application under extreme application of forces.
Soil-Structure Interaction (SSI)
Soil-Structure Interaction (SSI) is an important research topic in earthquake engineering, which has attracted extensive attention for several decades. As a branch of SSI, Structure-Soil-Structure Interaction (SSSI) is a key research topic during recent years. It is an interdisciplinary field of endeavor, which relies on the application of soil and structural mechanics, soil and structural dynamics, earthquake engineering, geophysics and geomechanics, material science, computational and numerical methods.
