The design output for composite beam as per LRFD 3rd edition code would look like what has been shown below. The software reports the moment capacity considering the composite section.

A gentle reminder for the below query.

Dear sir,

I tried with track 2 parameters but a report showing nothing for the composite beam. Kindly advise.communities.bentley.com/.../calc5-cb-7.7.std

The Design tab is not available for composite beam members because the output for the composite beam design is different compared to the output for non composite sections. You may use the TRACK 2 parameter to get a little more detailed output for the composite beam design.

Yes you need to use the RBH and THK. The RBH is correctly specified as 60mm but your THK should be 100mm.

Thank you, sir!

Dear sir,

I am waiting for the reply of the following query for one week. Kindly reply.

I am designing the composite beam.

1.but in results staad showing utilization ratio but not showing the steel design tab.although in the utilization table clause is not mentioned. How I can see how stad give this utilization ratio.(screenshot is attached)

2.is it necessary to assign the RBH AND THK parameter in design?If it is necessary did I assigned in my attached model correctly?.total thickness of concrete is 160mm from top flange of the steel beam to top of concrete slab.and the decking sheet height is 60mm.

When defining the composite section ( using the CM radio button within the Section Database ) you will be able to define the Density of Concrete (CD). Input that as 0
