Units & System of Units

Unit is defined as the numerical standard used to measure the qualitative dimension of a physical quantity. Mass or Force, Length and time are accepted as basic quantities, then all other quantities are derived quantities.

ü SYSTEM OF UNITS

         FPS : foot, pound, second
         CGS : centimeter, gram, second
         MKS : meter, kilogram, second
         SI     : System International

ü SI UNITS

Accepted throughout the world and is a modern version of the metric system. Length - metres (m), Mass - kilograms (kg), Time - seconds (s) are selected as the base units and Force in newtons (N) is derived from Newton’s Second law.

Electric Current – Ampere (A)
Temperature - Kelvin (K)
Amount of substance – mole (mol)
Luminous intensity – Candela (cd)

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

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
