hi Clearcal,
i would like to ask, if a single concrete beam with end to end 2 x supporting. (the size is 300mm of the supporting) shall I make the selection as attached photo?

Hey @Tztp_ping ! Thanks for posting here! This will of course depend on your engineering judgement - so take what I say with a grain of salt as I don’t have the full info of your project.
But if you’re designing for shear/moment/deflection, on a long span, I’d normally expect to see just one support at each end. Having two supports close to each other does some weird things with stiffness that can end up artificially decreasing your moment loads.
