The biggest difference between the
old and new codes should pay
attention to using the characteristic
value of bearing capacity instead of
the standard value.
The current norms correspond to the
selection of the foundation with the
standard value, that is, the bottom
area of the foundation, and the
calculation of the foundation should
not be confused according to the
The basis for settlement check
calculations required is different from
the old code, so be careful not to omit
The requirements for steel structure
foundation treatment (including filling
soil) should be clearly marked, all data
requirements should be filled in, and
corresponding information should be
submitted for new processes.
The pile type, bearing layer, bearing
value, test pile requirements, anchor
pile requirements, and settlement
requirements should be stated in the
selection of pile foundation.
The connection requirements of piles
and caps must meet the requirements
of the specification.
In addition to satisfying the requirements
of bending and shearing resistance, the
foundation should pay attention to local
pressure. At present, some foundations
often neglect the shear calculation
except for the calculation area.
