I have come across this topic in practice exams and find the more I study the more confused I get. If your given a long span in which a wood truss, glulam or a steel truss are all potential options, how do you know which one to use?
I know things like construction type, occupancy, aesthetics, constructability, delivery truck size (maximum typically 60') all come in to play however if those specifics are not given I'm finding it difficult to decipher between the right systems.
As an example, Architects Studio Companion lists Wood Glulam and Open Web Steel as long span options in most use cases however not Truss, why?
Any insights would be greatly appreciated.
