Further Due to Revision of Existing Codes the Design Seismic Forces Are Increased and Code Provisions Made Stringent to Avoid Damage Failures E.G., In the 2002 Edition of Indian Seismic Code Is 1893, Hyderabad Has Been Upgraded to Seismic Zone Ii from Seismic Zone I of the 1984 Edition. Hence Most of the Buildings Which Were Safe As Per the Previous Code Have Become Unsafe As Per Provisions of the New Code. Hence the Need to Determine the Seismic Safety of All the Existing Buildings and Strengthen the Weaken Ones to Resist the Seismic Forces Prescribed By the New Code. Hence the Importance of This Research Works. Further Most of the Existing Buildings Were Not Designed to Resist Even the Earthquake Forces Prescribed By the Old Code. There Is Greater Need to Evaluate the Seismic Safety of All Such Buildings As some of Them May Need Demolition to Avoid Loss of Life In Future Earthquakes. the Remaining Buildings Will Need Retrofitting and Repair.
A Constant Study Is Carried Out By Varying the Seismic Areas, Soil Type and Store Number, Etc., Changing Only One Parameter at a Time. a Method For Determine the Seismic Security of Existing Reinforced Concrete Structure Based on the Indian Seismic Code Is Proposed. the Results Are Validated By Comparing Them With Methods Currently In Use In Other Countries. It Is Hoped That the Method Developed Will Be Useful In Presenting a More Comprehensive Seismic Safety Evaluation Code For Use By the Indian Designers. the Need For Evaluation Arise ...
