Question
“Because the strain values are negative, does this mean that we keep it as a negative value? For example, when calculating the force in the top chord, if the max measure strain is left negative, the force will then be a negative value. Or, instead, do we put this number as a positive value?”
Response
Exactly what sign you use doesn’t matter so long as you’re consistent. You’d like to understand what it means. I suggest that you review Dr. Moon’s lecture notes to understand whether you expect the top chord to be in tension or compression. The sign will mean one or the other of those.
