Graphs To Assess Damage To Buildings If Earthquake Occurs

HYDERABAD: The International Institute of Information Technology (IIIT) Hyderabad has developed graphs to assess damage to buildings in the event of an earthquake.

It has installed hi-precision state-of-the-art building vibration sensors in Chandigarh which, it claimed, provides real time check of the correctness of the graphs.

The technology called 'Tool for Comprehensive Seismic Risk Assessment of Buildings (CSRAB)' has been developed by Professor Ramancharla Pradeep Kumar, head of the Earthquake Engineering Research Centre at IIIT and his research team.

According to Kumar, this new damage assessment method can clearly say by looking at a prototype score card what kind of damage a building can undergo in future earthquakes.

The score card is called the Rapid Visual score of the building.

In this, the damage can be categorised under five categories - no damage, slight damage, moderate damage, severe damage, and collapse.

He said risk assessment has three components - hazard, exposure, and vulnerability. Hazard is the level of ground shaking expected at any location, exposure is number of people exposed to such a hazard and vulnerability is current strength of buildings.
