Performance Of Various Parameters of Buildings Under The Composite Action Of Blast Load And Earthquake

Abstract

An earthquake (or quakes, tremors) is shaking caused by sudden movements of rocks in the Earth's crust. They can be extremely violent. Earthquakes are usually quite brief, but may repeat. They are the result of a sudden release of energy in the Earth's crust.

Some of the largest earthquakes of the world have occurred in India and the earthquake engineering developments in the country started rather early.This paper briefly reviews the development of earthquake resistant design of Indian structural buildings. Measurement of ground acceleration of ground started from 1930’s and data calculations were made possible in 1940’s. Design and development were formulated in late 1950’s to 1960’s. Non-linear response was introduced in seismic design in1960’s and capacity design concept was generally introduced in1970’s for collapse safety. The damage of statistics of reinforcement concrete building in 1897 Assam earthquake consideration the movement of building performance with the development of design methodology. Buildings designed and constructed using outdated methodology should be upgraded. Performance based engineering should be emphasized, especially for the protection of building functions following frequent earthquake.It has clearly underlined the inadequate preparedness of the country to face damaging earthquakes. The paper discusses the developments of earthquake engineering in India during the last one hundred years, the current status of earthquake risk reduction in India, strengths and weaknesses of Indian model of earthquake engineering developments, and the future challenges.
