RESEARCH FOCUS 1: ENVIRONMENTAL EFFECT ON DYNAMICS OF STRUCTURAL SYSTEMS

Team I4S is focused on the research on estimating the health of infrastructures and providing an optimal solution for restoring them.

EFFECT OF ENVIRONMENT ON HERITAGE INFRASTRUCTURE

Understanding the effect of temperature and other adverse environmental agents on heritage structures is an important step towards maintaining their health. Victoria Bridge in Mandi town is one such age-old steel suspended bridge that took its test of time. Our group is investigating its current health and expected service life.

Tension+Integrity; a unique structure type that is stable because of the prestress in its tension members. Team I4S is exploring newer ideas for form finding and stability analysis for this structure type. Besides, the variation of its dynamic behaviour under varying temperature is also one of our interest.

RESEARCH FOCUS 2: STOCHASTIC FILTERING AND SYSTEM ESTIMATION

Team I4S is developing novel Bayesian Filtering techniques for identification of complex stochastic systems using the noisy response measurements. Application for this research can be health monitoring complex infrastructures using their ambient vibration response.

NOISE ADAPTIVE ROBUST FILTERING TECHNIQUES

Robust Bayesian algorithms are one of the team's major interest. In this attempt, noise adaptive algorithms that are robust against measurement outliers and sudden change in the system are developed.

MODELLING AND ESTIMATION OF STRUCTURAL DAMPING

Damping in structural systems is still a mysterious topic for research. Hardly there is any model or estimation technique that can perfectly model/estimate damping in a system. This team is focusing on developing techniques for an efficient modeling approach that takes its basis on estimated damping values.
