Also, in lightI wouldn't think so. I assume you mean they are lapped 2.5' over the supports. The purlins are then free to deflect independently (i.e. no momentash060- how would the transfer of moment work? I assume the flanges are not connected to one another in order to transfer rotation (and moment). DThere have been a number of threads about these - just take a look (search).
