Steel Bar Design

[Anonymous]

Hello,

Happy new year to everyone

I just saw webinar 3 (steel design) and I got the following questions:

What is the correct way to model and design the element, in this case a purlin. (see the following captures)

1. To model a single element (742) from node 630 to node 618 and assign design parameters

2. To model elements separated by nodes (663, 664, 665) and define a "superbar" to assign design parameters

Is there any difference? What is the correct practice? Design parameters are the same in both cases, right?

Thanks in advance

What is the way you'd measure the deflection limit(s) for this purlin: between end nodes or for each of 'spans' separately?

That's a good point.

The structure is something like this:

I'd measure deflection limits for each of spans separately.
