I’m modeling a composite bridge to run modal analyses and understand the natural frequencies of the bridge and I need some advice.
I’m using a beam model with a composite thin walled section and I’m wondering whether the effective width of the concrete is calculated automatically by aqua. From a few tests and the manual I’d understand it does, but how?
Also, in one of the tutorials it is suggested to use a shear connection with a width of 100mm between the top flange and the concrete, what is the range that can be used and why 100mm is suggested?
A big thank you to everyone that can help with this doubts
