IS 1893 (Part 1) : 2016 - Criteria For Earthquake Resistant Design Of Structures - General Provisions And Buildings


The provisions of this standard are applicable for design of structures like parking structures, security cabins and ancillary structures taking into account appropriate earthquake effects as per this standard. This standard is also applicable for design of temporary elements, such as scaffolding and temporary excavations.

This standard does not deal with construction features relating to earthquake resistant buildings and other structures. For guidance on earthquake -resistant construction of buildings, reference may be made to the latest revisions of the following Indian Standards:  IS 4326, IS 13827, IS 13828, IS 13920, IS 13935 and IS 15988.

The provisions of this standard are applicable even to critical and special structures, like nuclear power plants, petroleum refinery plants and large dams. For such structures, additional requirements may be imposed based on special studies, such as site-specific hazard assessment. In such cases, the earthquake effects specified by this standard shall be taken as the minimum.


The standard includes detailed provisions on general principles and design criteria for earthquake hazard assessment such as  load combinations,  design acceleration spectrum to be used for  determining design seismic force; detailed provisions on buildings  covering therein building configurations, plan irregularities and  vertical irregularities of buildings that needs to be addressed in the planning, calculation of the  estimated lateral force  on buildings  based on suggested factors including on response reduction factor and importance factors for buildings, determination of approximate fundamental transnational natural period of  buildings with basements, step back buildings  and  buildings on hill slopes,  reinforced concrete frame buildings with un-reinforced masonry infill walls and for those  with  open  storeys,  flat slab structures,  permissible deformation limits,  procedure for evaluation of liquefaction potential of soils, etc. Various maps of India depicting seismic zonation, epicentres of past earthquakes, principal tectonic features, principal lithological groups have also been provided.

IS 13920 : 2016 -Ductile Design and detailing of reinforced concrete structures subjected to seismic forces-Code of practice

IS 13920 : 2016 - Ductile Design and detailing of reinforced concrete structures subjected to seismic forces-Code of practice  since it was first published in 1993. Most of the older provisions have been redrafted and modified for greater clarity and new provisions have been added. Much of the this revision is based on the IITK-GSDMA document of proposed draft provisions. To Download II    Click Here    II

SP 16 :1980 - Design Aids for Reinforced Concrete to IS:456

The structural practice handbook  SP:16-1980   Design Aids for Reinforced Concrete to IS:456-1978  has tables and charts that helps structural engineers to rapidly design simple sections. Even though the design aid is based on the 1978 code, it continues to be used without revision as there have been no major changes to Section 5, on which the design aid is based.

------------- Repair and Rehabilitation of Concrete Structures --------------- By, Poonam I. Modi & Chirag N. Patel

Since the subject of repairs and  rehabilitation is very exhaustive and entails great complexities /  varieties in terms of types of distress / deterioration, materials and techniques available for repairs and rehabilitations, it has always been a daunting task for the authors to select aspects to be covered in this book.  Following sections gives the panoramic view of this book organized into six chapters: Chapter 1 (Introduction)  gives quick overview and relevance of repairs and rehabilitation of  structures besides outlining general scenario of prevalence of deterioration of concrete structures,  broad reasons for distress in structures explaining what can go wrong with structures, and a general  roadmap and steps to be followed for carrying out any structural repairs and rehabilitation. This section also defines some of the important terms that are used in this book. Chapter 2 (Distress in Structures- Serviceability and Durability...
