Designing According to the Chinese Building Code 1

[PEFLWI]

Has anyone had to design per the Chinese Building Code?
How similar is it to the IBC?
Is the steel and concrete design similar to ASIC and ACI?

I had to envelope the GB codes and IBC for a project in China over 10 years ago. I remember the GB codes being different in many ways. I don't think there is a lot of direct cross-over with US codes, but the underlying principles are similar of course.

If you have any specific GB code questions, I still have an English-translated copy of GB50009-2001 and a Chinese copy of GB 50010-2002.

bones206:
would you be willing to upload GB500092001?

Thanks.

I'd prefer not. Don't really want to paint a target on my back. But I'm happy to look up specific provisions if that would be of help.

 

[PEFLWI]

Does the steel specification use allowable stress design? How does it handle stability? Does it use the old alignment chart approach?

Sorry I've been very busy lately and hadn't had a chance to look into this.

3 Basic design requirements

3.1 Design principles

3.1.1 For all calculations except fatigue calculation, the limit state design method based on probabilistic theory is
adopted, using design expressions with partial safety factors.
3.1.2 Load-carrying structures shall be designed according to the following ultimate limit states and
serviceability limit states:

1. The ultimate limit states include: strength failure of members and connections, fatigue failure and
excessive deformation no longer suitable for carrying load, loss of stability of structures and members,
formation of mechanism and overturning of the structure.

2. The serviceability limit states include: deformations affecting normal use and appearance of a
structure, structural and non-structural components, vibration affecting normal use, local damage
(including concrete cracks) affecting normal use or durability.

3.1.3 In the design of steel structures, different classes of safety shall be adopted according to the
consequence of damage which may be caused by a structural failure.
Steel structures of industrial and civil buildings, in general, shall be taken as safety class 2, whereas for
a special building structure the safety class shall be dealt with individually in conformity to its actual
condition.

3.1.4 In designing a steel structure according to the ultimate limit state, the basic combination of load
effects shall be considered and, if necessary, the accidental combination of load effects shall also be
considered.

In designing a steel structure according to the serviceability limit state, the normal combination of load
effects shall be considered, whereas for composite steel and concrete beams, the quasi-permanent
combination shall also be considered.

3.1.5 In checking the strength and stability of structures or structural members and also the strength of
connections, the design value of loads shall be used (i.e. the characteristic value of loads multiplied by
partial safety factor for loads), whereas in checking fatigue, the characteristic value of loads shall be used.
