I appreciate JAE's reply. It does seem ridiculous to design for full load in the longer direction when the shorter direction takes more of the load. I've read that slabs should be designed for equal deflection in each direction. That is where the deflection is the fourth power ratio of the length to the width, thus for both directions to act together, the load should be apportioned according to that ratio. That makes perfect sense to me. To design for the longer direction taking full load, that reinforcement would never be activated. Does the ridiculous actually rule and common sense become the ridiculous?
