Aims at seismic microzonation of a city, laboratory investigation of seismic behaviour of pile and full-scale confined masonry buildings to draw design features for earthquake resilient constructions.
The main concerns under engineering of earthquake disaster mitigation are minimizing the damage and to ensure the buildings are safe against earthquake. In past decade, CSIR-CBRI has attempted to undertake the studies in pilot scales in and around Delhi, Jabalpur and Dehradun. Several approaches have been followed at International level on modal testing of buildings for confined masonry structure and pile foundation. However, no concerted efforts have been made to evaluate the seismic behavior of buildings under varying stress conditions. As a consequence, an efficient seismic analysis and design of buildings has not been yet established in practice for earthquake resistance. Internationally, seismic micro-zonation of cities has been attempted by most of the developed/developing countries, by adopting different approaches as a preparedness measures. However, due to complex geological and geotechnical conditions of Himalayan region the same need to be carried out in India as well.
