General
The material properties given in this section are
nominal values, to be accepted as characteristic values
in design calculations.
Structural Steel
The provisions in this section are applicable to
the steels commonly used in steel construction, namely,
structural mild steel and high tensile structural steel.
All the structural steel used in general
construction, coming under the purview of this standard
shall before fabrication conform to IS 2062.
Structural steel other than those specified in 2.2.2
may also be used provided that the permissible stresses
and other design provisions are suitably modified and
the steel is also suitable for the type of fabrication
adopted.
Methods of Design
Structure and its elements shall normally, be
designed by the limit state method. Account should be
taken of accepted theories, experimental information
and experience and the need to design for dumbi]ity.
Calculations alone may not produce Safe, serviceable
and durable structures. Suitable materials, quality
control, adequate detailing and good supervision are
equally important.
3.1.2.2 Where the limit states method cannot be
conveniently adopted; the working stress design (sef~
Section 11) may be used.
3.1.3 Design Process
Structural design, including design for durability,
construction and use should be considered as a whole.
The realization of design objectives requires
compliance with clearly defined standards for
materials, fabrication, erection and in-service
maintenance.
Loads and Forces
3.2.1 For the purpose of designing any element,
member or a structure, the following loads (actions)
and their effects shall be taken into account, where
applicable, with partial safety factors find combinations
(see 5.3.3):
Limit State of Serviceability
Serviceability limit state is related to the criteria
governing normal use. Serviceability limit state is limit
state beyond which the service criteria specified below,
are no longer met:
