- Ground motion characterization for seismic design and performance assessment is one of the thrust areas. This includes various aspects including the characterization of multi-component seismic excitation, spatial variability of ground motion, critical orientation, probabilistic seismic hazard assessment, choice of ground motion intensity measures, ground motion prediction equations, selection and scaling of ground motion for performance based earthquake engineering etc.
- Understanding the behaviour of irregular buildings involving asymmetry, setbacks, in-plane floor flexibility etc. and the long span bridges subjected to multi-component spatially varying ground motions is one of the science questions that we have been aiming to address.
- Seismic resilient structural design with and without using passive control is another thrust area. We explore various possible applications of supplemental devices including dampers and their mounting system.
- High performance fibre reinforced concrete (HPFRC) and its possible contribution to the seismic resistance is another direction where we have been focusing. We explore the constitutive properties of HPFRC and possible contributions from the metallic and non-metallic fibres with varying shapes.
- Characterization of system properties and damage localization through ambient signatures is another area we have been exploring.
- Our group is awarded with research funding from several agencies including DST, CSIR, MoES, STARs/MHRD, GUJCOST and SERB.
