Re: DILATATION PROBLEM Mr. recessive_07 MY RECOMMENDATIONS; -- Delete and re-enter the pool decks D43 and D62, (The support is corrected incorrectly.) -- Correct the geometry control errors, -- Too many beam spans (clear span 9 m and exceeds the deflection limit.) increase beam height slightly, -- recovery in columns enlarge the sides, -- If there is water in the pool, take the water load on the curtains and on the floor, -- 200 kg load on the floors seems like little to me. Good luck with. Unver ÖZCAN
