For a beam 50ft long, laterally braced at the center.Dead .2k/ft Live .8k/ft
I set the unbraced length in two ways, one way is assign a translation restraint at the center, this way gives a correct answer.
Another way is use the overwrite to set the LTB ratio as .5.But this give me a different design section.This way is from the manual
Could anyone tell me what is the reason ?
Thanks
