composite beams design using IS800:2007

Question

we are using latest version 20.07.11.45 Build of SS6. 
 using Deck generation method for composite Slabs. 
 using code IS800 :2007 LSD & WSD , design of composite beam is showing ' WARNING: DESIGN OF SECTION FOR MEMBER # 7 IS NOT SUPPORTED.' 
 Using I800 : 1984 WSD the Program is design the beams. 
 Kindly Guide How to design the Composite beams using IS800: 2007 LSD & WSD.

The composite beams or the composite deck design facility in Staad is only available for the AISC Code. For more information on the composite section design in Staad you may refer to the chapter no. 1.7.7, 2.4.1.7 and 2.5.13 of the Technical Reference Manual.

As you have confirmed that STAAD is supporting composite beam design using AISC. but when we are using the IS800 : 1984 design code the composite beams are showing the results. Are these results with composite design or W/o composite design. should we follow these results????. STAAD file is also attached.

Hi, 
 
Although IS IS800 : 1984 code delivers the design results in the output file for the composite member system but here the design is simply done for the steel section, the concrete section is simply ignored and hence the compotire section design is not performed per Indian code.
