Im designing a multistorey building. after i check the beam steel, it is coming very minimum. so i deleted all the loads and only self weight is applied. i noticed that my slab self weight is not being transferred to beam. my bema is 300x600 so in the equivalent load only 4.5kN/m is there which is the self weight of the member. but the beam and slab are in the same level. the joints are correct and the shell thin is used to design the slab. what do i do in this situation
