Steel composite bridge

Hi all.

I hava some question about steel composite brige as follows:

1. To calculator stress point of section, Rm Bridge automatic use short-term section for live load and load case type Non-permanent and use long-term section for load case type Permanent?

2. To check Negative moment and positive moment of section composite, Rm Bridge use UltSup to check Moment Strength I, II, and III. Other way, to check section steel as flange and web, we use UltRes and ResChkSup to check?

3. To calculator deflection of steel composite bridge, RM Bridge automatic use short-term section to calculator?

Thank you for reading and hope get your reply.

Best regards.
