Weld

Welding connection between steel members could take up axial tension, shear and bending moment.

For fillet welds, the connection strength depends on the weld thickness.

In general, the welds in the flanges are used for resisting bending moment and welds in the web are used for resisting shear.

The following is a example for checking of weld strength for a UB section:

As-built Drawings from BD

In the past, if you want to obtain the record plan from the Buildings Department, you have to fill in the Appendix of PNAP110 and return the Form to 13/F of the Buildings Department's office.

In January 2009, BD has launched online system BRAVO which allow the public to access the record plan system.

In order to view the list of record plan for a specific site, you have to pay $36 first. The BRAVO system does not allow copying and screen capture for the drawings. You have to pay for printing of the record plan.

However, you could in fact save the record plan (in tiff format) to your local computer.

The BRAVO system use viewone to view the record plan. The temporary files will save at c:\user\Your_Username\Viewone\cache

The BRAVO system has disabled the copy & paste function of Window System. In order to save the files, you have to zip the record plan into zip file and then MOVE the file to other folders.

For viewing calculation, you can press "F3" in order to save all pages at the same time.

However, you need to decode the ".tif" files by a small programme "decode.exe" with the following command in DOS mode:
"decode OLD.tif NEW.tif"

You may use batch file if you wish to decode many files.
This trick can really help you saving a lot of money.
