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.

                                                                                                                                                             

 

 

 

TENSEGRITY STRUCTURE

  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.

                                                                                                                                           

 

 

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.

 

                                                                                                                                     

 

 

Thermo-mechanical Analysis of Mass Concrete 

Early age cracking is a critical issue in mass concrete due to the development of high thermal gradient at early stage because of high heat of hydration. The team is working to model the internal heat of hydration with incorporation into a thermo-mechanical numerical model for further analayis with validation against a real test case of 1 cubic meter volume.
