Chinese Code GB 50007-2011

STAAD Foundation Advanced now supports the standards for foundation design for China per the GB 50007-2011 Code for design of building foundation for the following types of foundations:

1. Isolated footings that have a sloping profile (also known as sloped footings or tapered footings)
   
2. Isolated footings that have a stepped profile (also known as stepped footings)
   

Both these features are available through the General mode of the program.

Modification to the Parameters Used in Length and Width Increments for Footing Sizes

In past versions of STAAD Foundation Advanced, for isolated footings the Footing Geometry page had two options known as Plan Dimension Increment and Length/Width Ratio.

As a result of this change, two of the options previously available named Fixed Width and Fixed Length (available when Calculate Dimension was selected as the Design Type) are no longer available. Fixed Width can be simulated by setting the Dim Increment Along Global Z to 0.0. Similarly, Fixed Length can be simulated by setting the Dim Increment Along Global X to 0.0.

Refer to Footing Geometry form (Isolated Footing) for additional details.

Other Enhancements

1. Defects that were reported on design of pedestals per the ACI code for isolated footings have been rectified. However, as a result of this change, only a limited amount of details are currently provided in the output. The full extent of the details of the calculations, as was available in past versions, will be restored in a future version.
2. The design of isolated footings per the US code has been enhanced to reduce the time it takes to calculate a suitable footing dimension. This improvement should be most noticeable in jobs where there are several footings being designed to several service and ultimate load cases.
3. Some errors in the seismic design of vessel foundations per the Indian code have been corrected.
4. Some errors in the analysis and design of Tank foundations have been corrected.
5. A representative sketch showing the pile arrangement is henceforth included in the calculation sheet for jobs where a pile arrangement is calculated prior to the design of the pile.
   

   For SFA files which were created using past versions, the engineer will have to re-generate the pile arrangement and re-run the analysis if he/she wishes to see the sketch appear in the calculation sheet.

6. For mat foundations on piles, mesh generation failed in earlier versions of the program for situations where pile springs were defined outside the boundary of the mat region. This has now been rectified.
7. An error which caused the beta angle of the column to be ignored when the foundation design was launched from within STAAD.Pro has now been corrected. For beta angles that are not a multiple of 90 degrees, the column is assigned a dimension which equals to the sides of the smallest bounding rectangle whose sides are parallel to the global X and Z axes.
8. An error that caused the sign to loads to be erroneous when they are derived from support reactions imported from an ISM file has been corrected.
9. Several new instructive messages informing the user of potential errors in the input have been included for various modules. An example of such a message would be one which advises the user to re-mesh the mat if any of the parameters affecting the mesh generation, such as pile positions, coordinates of loaded areas and control regions, are modified.
