How are slab reports load calculation made?

[engineer_yildiz]

DEAR IDECAD FAMILY (FORUM USERS AND FOLLOWERS, AUTHORITIES) IN ORDER TO LOOK SIMPLE BUT THE POINTS THAT CAN BE OVERLOOKED ARE UNDERSTANDABLE: 1- RIVER AND CASSETTE FLOORING IN THE FLOOR REPORTS" IN THE FILE". HOW DOES THE PROGRAM DO ITS CALCULATIONS? 2- CAN YOU EXAMPLE USING THE VALUES IN THE ATTACHED PICTURES? 3- WHEN WE WANT TO FILL THE RIBBON AND THE CASSETTE BETWEEN THE FRAME 3A) HOW SHOULD WE INTERVENT THE PROGRAM? 3B) CAN YOU SHOW A CALCULATION EXAMPLE FOR THE HOUSING FILLING CALCULATION BY REFERENCEING THE ATTACHED PICTURES?

Hello dear engineer_yildiz, For Rib, 1. The value of 450 + 57 appearing in the report means the following. 0. 450 tf/m total fixed load on the slab -> (ConstantLoadValue you entered + SlabLoadWeight) + Rib Beams Spacing D(for 1 meter) (FixedLoadValue + SlabLoadWeight you entered) ) = 0.15 + 0.12*2.5*1 = 0.450 tf/m (This value is the value of 450 appearing in the report.) tooth weight = (RibBeam Height H - Rib Slab Thickness d) *concreteUnitWeight *1 tooth weight = (0.35- 0.12) *0.1* 2.5*1 = 0.0575 tf/m (The slab height is subtracted because the slab self-weight is taken into account one above. This is the 57 kgf/m value shown in the report.) As rounding visible in NZ03 is 450 +57 kgf/m . 2. The slab constant load value that appears on the report is 0.22 (for NZ02): (the ConstantLoad Value you entered + the FloorTreeWeight)*(RibBeamTeeth Width w + 2*RibBeams Spacing D/2) (for 1 meter) (0.15 + 0.12*2.5) * (0.1+2*0.4/2) * 1 = 0.45 * 0.5 =0.225 tf/m Self weight = [(RibBeam Height H- Rib Tile Thickness d ) *RibBeamTooth Width w *ConcreteUnitVolume*1 = (0.35-0.12)*0.1*2.5*1 = 0.0575 tf]/m[/ Total constant load = 0.225 + 0.0575 = 0.2825 tf/m [ u]3. If the value of 0.14 tf/m for the cassette is[/u] Since the cassette has teeth in both directions, load analysis is performed within a ratio depending on the tooth spacing. In the 2nd direction, Ratio2 = CassetteBeamsRange D1 /(CassetteBeamsRange D1 + CassetteBeamsRange D2) Ratio2= 40/(40+40) = 0.5 (the ConstantLoadValue you entered + SlabLoadWeight)*(CassetteBeamToothWidth w + CassetteBeamsRange*1 (Ratio for 1 meter)) (0.15+ 0.12*2.5)*(0.10+0.4*0.5)*1 = 0.135 tf/m Self weight = [(CassetteBeamHeight H- CassetteFloorThickness d) *CassetteBeamToothWidth w*ConcreteUnitVolumeWeight*1 = (0.35-0.12)*0.1*2.5*1 = 0.0575 tf/m[/size ] Total constant load = 0.135 + 0.0575 = 0.1925 tf/m

3- WHEN WE WANT TO FILL THE FILLING BETWEEN RIBBON AND CASSETTE 3A) HOW SHOULD WE INTERVENE WITH THE PROGRAM?

You should add the hollow block weight as the weight per square meter to the load you entered in the flooring settings.

According to the above calculation, if we consider 1 tooth in 1 m, I think the calculation may be missing. In STA4CAD, N 15/30 for 55 cm unit, 15 cm tooth in 40 cm, hollow slab load calculation for 7 cm slab thickness is as follows: G concrete layer + tooth = 0.07x0.55.1.0 + 2.5x0.15x0.23x1.0 = 0.1825 tons of bricks =0.7x0.23x0.4 =0.064 ------->there may be an error here if you ask me. 0.1825+0.064 =0.2465 tons 0.2465/0.55=0.449 t/m2 ----------->what ratio in 1 m2 0.449+0.17=0.619 t/m2 ------>tile coating + hollow block brick+concrete cover and tooth The values that Mr. Serdar shared with me in this way, when I do it myself in idecad, I find it to be 0.445+0.086=0.531 because I bought a total load of 0.1 ton/m2 of hollow brick. Some of our friends in the municipality say that the load is missing in order to take them to the safe side and they send it.

when I do it myself in idecad, I find the total load to be 0.445+0.086=0.531 because I bought 1 ton/m2 of hollow brick. Entering it as a coating value will provide sufficient data entry for you to consider the hollow block load.

Hello, ideCAD' In addition, adding the m2 weight of the hollow block brick to the coating weight and entering it as the coating value will provide sufficient data entry for you to consider the hollow block load. m wants me to do it.

Hello ; I calculate the toothed slab infill weight as follows and use it in the slab load analysis I made in the "Settings - Load library - Slab load library" section in 7.022.

Hello there. First of all, what is Tg? And I will use the hollow block material Bim Filler. Unit volume weight is 500 kg/m3. Is it okay if I use 0.15+Tg now?

Hi. First of all, what is Tg? And I will use the hollow block material Bim Filler. Unit volume weight is 500 kg/m3. Is it okay if I use 0.15+Tg now? in the top post (

) The Tg index is shown as the weight of the hollow block filling material. It is explained once again below to ask you again. The weight of the hollow filling material should be calculated according to the material used and added to the coating weight.

Thank you.
