This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Earthquake Engineering Sectional Committee had been approved by the Civil Engineering Division Council. This standard is intended to reduce the risk of death and injury that may result from the damaging effects of earthquake on building which predate the current seismic codes [IS 1893 (Part 1) : 2002 ‘Criteria for earthquake resistant design of structures: Part 1 General provisions and buildings’, IS 4326 : 1993 ‘Code of practice for earthquake resistant design and construction of buildings’ and IS 13920 : 1993 ‘Ductile detailing of reinforced concrete structures subjected to seismic forces — Code of practice’] or have not been designed for earthquake forces. This standard describes a set of key steps and procedures for the assessment of the expected seismic performance of existing building in the event of a design level earthquake and where found necessary, strengthening of existing structural systems and elements for improved seismic performance. Seismic forces for evaluation criteria of existing buildings are different from those meant for the design of new buildings. Appropriate modifications are made to address the issues of reduced serviceable life and acceptable risk for higher importance. Further, to account for uncertainty in the reliability of available information about the existing structure and the condition of structure components, strength calculations need to be suitably modified. For deficient buildings, a broad outline for the design seismic strengthening measures has been developed and the interface with current design codes in general terms has been identified. In the formulation of this standard, assistance has been derived from the following publications: Code: *************************************** |
