DESIGN  Of  BUILT-UP  MB SECTION : PROGRAM INFO./LIMITATIONS. ( Actual program is available in Super Civil CD )
This program designs Built-up ISMB  section under axial load and bending moment. The bending moment can be about X-X axis or Y-Y axis or both together. Built up section consists of flange plates of equal sizes  placed at the  top & bottom of ISMB section.
Structural steel design is as per Indian Standard No.IS:800-1984.
Yield stress fy = 250 Mpa. E = 200000 Mpa.
Increase In stress factor is applied to permissible stresses, hence stress ratio is always taken as less than or equal to one.
Only following ISMB  members are used in design.
MB100	MB150	MB200	MB250	MB300	MB350
MB400	MB450	MB500	MB600
