GEOLOGICAL SETTING OF DELHI
Delhi, the capital of India bounded by the IndoGangetic alluvial plains in the North and East, by Thar desert in the West and by Aravalli hill ranges in the South. The terrain of Delhi is flat in general except for a low NNE-SSW trending ridge which is considered and extension of the Aravalli hills of Rajasthan. Seismicity around Delhi appears to be associated with a major geological structure, which is known as the Delhi-Hardwar Ridge.
DELHI & SEISMIC ZONING
Delhi located in zone IV which has fairly high seismicity where the general occurrence of earthquakes is of 5-6 magnitude, a few of magnitude 6-7 and occasionally of 7-8 magnitude. Delhi thus lies among the high-risk areas. In the past, five earthquakes of Richer Magnitude 5.5 to 6.7 are known to have occurred in the UT of Delhi or close to it since 1720 AD. Two major lineaments namely DelhiHaridwar ridge and Delhi-Moradabad faults pass through the territory. Normal depth of 30 km may be assumed for these earthquakes.
Pockets with high rise buildings or ill-designed highrisk areas exist without specific consideration of earthquake resistance. The Central Business District namely Connaught Place, numerous District Centres and sprouting high rise group housing schemes are high risk areas due to the vertical as well as plan configurations. The walled city area, the trans-Yamuna area, and scattered pockets of unplanned settlements also figures as high risk zones due to their substandard structures and high densities. The city's settlement pattern needs to be viewed in relation to location and geological characteristics.
DELHI & EARTHQUAKES – A HISTORICAL PERSPECTIVE
Mahabharata mentions about earthquakes during the war at Kurukshetra (Circa 3000 BC). Earthquake of year 893 or 894 which took place not far from Delhi in which many persons died 1720 earthquakes (intensity IX in Delhi) Earthquake of 22 March 1825 (Intensity VI) Earthquake of 17 July 1830 (Intensity VIII) Earthquake of 24 October 1831(Intensity VI)
DELHI & EARTHQUAKES – RECENT HISTORY
Khurja earthquake (M6.7) of 10 October 1956 in which 23 persons were killed in Bulandshahr Earthquake (M6.0) of 27 August 1960 near Delhi wherein about 50 persons in Delhi were injured Earthquake near Moradabad on 15 August 1966 that killed 14 persons in Delhi. Damage to one of the minarets of Delhi's Jama Masjid during the (M4.0) earthquake on 28 July 1994. 1999 Chamoli earthquake (M6.5) took place about 280 km from Delhi. Several buildings in Delhi sustained non-structural damage possibility due to peculiar geological and geotechnical features if this area.
IT IS THEREFORE SEEN THAT DELHI IS PRONE TO SEVERE EARTHQUAKE DAMAGE BOTH BY NEARBY EARTHQUAKES AND BY LARGE EARTHQUAKES OCCURRING IN THE HIMALAYAS.
DELHI – STRUCTURAL SAFETY BACKGROUNDER
Vital issue of the earthquake safety performance of buildings, ancient monuments & infrastructure in Delhi, the capital city of India. As per Vulnerability Atlas of India (1997), for shaking intensity VIII, 6.5% houses in Delhi have high damage risk , and 85.5% houses have moderate damage risk. Most buildings in Delhi may not meet codal requirements on seismic resistance Disaster prevention involves engineering intervention in buildings and structures to make them strong enough to withstand the impact of natural hazard.
STRUCTURAL SAFETY & BUILDING CODES IN INDIA
Bureau of Indian standards, the National Standard Body of India, is a Statutory Organization under the Bureau of Indian Standards Act 1986. One of the activity is formulation of Indian Standards on different subjects of Engineering through various Division Councils. Bureau of Indian Standards has laid down the code of practice for design criteria of structures. Bureau of Indian Standards (BIS) has published the following seismic codes
IS : 1893 (2002) – criteria for earthquake resistant design of structures IS : 4326 (1993) – earthquake resistant design and construction of buildings IS : 13827 (1993) – earthquake resistance of earthen buildings IS : 13828 (1993) – earthquake resistance of low strength masonry buildings IS : 13920 (1993) – ductile detailing of RCC structures IS : 13935 (1993) – repair and seismic strengthening of buildings
BACKGROUND –
This multi-year project funded by the U.S. Agency for International Development (USAID) was designed to improve earthquake safety in several major cities in India. In particular, it addressed the vital issue of the earthquake safety performance of "lifeline buildings" (i.e., important facilities) in Delhi, the capital city of India. Delhi is located in seismic zone IV, the second highest earthquake hazard zone in India. Many lifeline buildings could be damaged when earthquakes strike, limiting the government's ability to deliver critical services.
RESPONSE –
To improve seismic safety in India by building capacity to undertake seismic assessment and retrofit projects. An experience-based, hands-on approach, pairing highly regarded and experienced US practitioners from the private, public, academic, and non-governmental sectors with local Indian counterparts to transfer knowledge and arrive at locally appropriate solutions. Five lifeline buildings selected to be retrofitted as part of this project - the Delhi Secretariat, the Delhi Police Headquarters, Ludlow Castle School, several buildings at Guru Tegh Bahadur (GTB) Hospital, and the Delhi Divisional Commissioner's Office.
Ludlow Castle School was retrofit using a prescriptive system of micro-concrete "seismic belts" developed in India and specified in the Indian building code. Two concrete office buildings at the Delhi Divisional Commissioner's Office complex were retrofitted using reinforced concrete shear walls. The retrofit scheme for the Secretariat was to consist of "wrapping" columns to improve their ability to deform during an earthquake Police Headquarters was to be retrofitted using a combination of new shear walls and modification of existing walls. At GTB Hospital, the retrofit was to consist of anchoring interior brick partition walls and equipment.
MODEL SCHOOL – development of comprehensive awareness and evacuation plans, conduct of preparedness drills, and commencement of structural retrofitting in Delhi’s government schools. Capacity building in earthquake engineering among Delhi government engineers. The Delhi Public Works Department created a "circle" for seismic retrofit within its organization Demonstrated how to identify vulnerabilities in buildings and how to reduce earthquake risk. Educated stakeholders about nonstructural concerns (falling hazards) that can pose immediate danger to building users, even without the occurrence of an earthquake. Produced a set of earthquake safety training manuals for teachers and students
STRUCTURAL SAFETY – CONCERNS & ISSUE AREAS FOR FUTURE
No legal framework to require that all constructions in Delhi must implement seismic code provisions. Systematic studies are needed on vulnerability of different types of constructions in the NCT of Delhi. Need to develop a rational seismic retrofitting policy, first for the government- owned buildings and later for the private constructions. Need for updating seismic code especially with regard to construction of bridges, flyovers & metro projects.
The Parliament enacted the Disaster Management Act in 2005. The Act envisages the formation of : National Disaster Management Authority (NDMA), State Disaster Management Authority (SDMA) & District Disaster Management Authorities (DMAs). Accordingly, the Delhi Disaster Management Authority (DDMA) was formed at NCT level in March, 2008. Eleven districts DMAs have been formed at district level.
The Disaster Management Act 2005 establishes:
