Notes on Safe Load Tables for Budabar-T-Bars
The Buda-T-Bar is imported from China, material used is Q235B, Q235 material is in accordance with PRC standard GB 700(previous version GB700-79 part A3 & C3), and here Q stands for yielding. According to PRC
National Standard GB700-88, the minimum yielding point is 235Mpa for thicknesses less than 17mm, tensile strength is between 375-400MPa, E=200~210 GPa
- The Buda-T-Bar is simply supported at both ends.
- The Buda-T-Bar is loaded such that the load acts vertically and equally on both sides of the web.
- The Buda-T-Bar is considered as being laterally unrestrained for the full span length.
- UDL loads are constant along the length of the bar.
- Point loads act at mid-span.
- 150mm minimum bearing support on to brickwork.
- Hot-dip galvanising to AS / NZS 4680:2006.
- Loads are in accordance with AS / NZS 1170.1:2002.
Note:
- a minimum of three courses of bricks must be laid above the lintel beam.
-
Load limited by deflection of 1/500 span. - Yielding stress fy=235 Mpa, tensile strength fu=375Mpa for both web and flange.
- Mass per metre calculation is based on 7850kg/m^3.
- Calculate bar length is span+150mm each end.
