The connection points of the frame are on the top and perpendicular to the side. I had significant snow load on the shelter, and the load bearing became in direct alignment with the frame connections and they all bent. I liked everything else about this shelter but itn is not able to withstand more than 12" of snow load considering at some point it will melt and become very heavy. Perhaps if the connection points would have been at 45 degrees to the load, or reinforced in some manner, the shelter should have been able to manage the load as it appeared to be very sturdy when I constructed it. I wish I had known about the load limitations as I would have bought the premium frame instead. Now I am back to needing a new shelter as the frame no longer has any integrity to handle even a minor amount of snow.
