Question

Quizplus · Accepted Answer

The question mentions that one type of girder is a built-up wooden girder, which suggests that the other type is not wooden. Steel girders are a common alternative to wooden girders and are often used in floor systems for their strength and durability. Cement girders are not a common alternative to wooden girders, as they would be extremely heavy and difficult to work with. Rebar girders are typically used to reinforce concrete and are not a viable option for a wooden floor system. Spiral girders are not a common type of girder and would not be a likely answer. Therefore, the best choice is A) steel girders.
