Beam deflection error in cassette flooring

[pelinimo]

Hello, I am solving a 2-storey villa as cassette flooring. I couldn't save my 2 beams from the deflection error. Can you help me? I also enter the floor as 10 cm and the cassette tooth height as 35 cm. Since I want to make the beams as horizontal beams, is it a suitable solution if I increase the beam height to 40 cm, make my floors 15 cm and make the cassette tooth height 40 cm? Do I have to remove the flooring by 15 cm so that the cassette teeth remain 25 cm? My project is attached.

Hi, I recommend increasing the beam heights to overcome the deflection problem. Increasing the beam pressure reinforcement also contributes to the reduction of the deflection value. In addition, when the elastic deflection value of the beam is examined in the analysis model window, it is seen that it reaches higher values than the deflection value calculated depending on the cracked section rigidity in TS 500, I recommend you to examine these values as well. If you want your cassette teeth to remain clean at 25 cm, you should choose 15 cm plate thickness at 40 cm tooth height. Good work.
