In the past century, a new form of concrete evolved called prestressed concrete. In prestressed concrete, initial compressive stress is induced in the concrete before actual loading. So, it can withstand tensile stresses in a better way.
IS:1343-2012 comprises the criteria and necessity for prestressed concrete members. It gives the general requirements of details, material, workmanship, and technology.

In IS 1343: 2012, the discussion of prestressed concrete is divided into 4 sections.
The section 1 is General section describing symbols used in code and reference, the scope of the code and terminology is given.
The section 2 is on material, workmanship, and inspection and testing.
The section 3 in IS 1343: 2012 is on the design requirements of the prestressed concrete elements.
The section 4, the last one is dedicated to structural design with limit state design theory.
