Are the slab loads entered together with the pavement and the self?

[iek58]

When I calculate my hollow slab load, it comes to 0.684 tf/m2. When I right click on the tile and try to enter a "user defined" load, I enter 0.684 in the grabber section, but G=0.872 in the plan view. Is this because it only takes the entered user value as an overlay? calculating user value + program defined load (0.684+ approx 0.2)? if so, should we enter the slab load we found by reducing it by about 0.2? Finally, what are your dead and live loads that you use in hollow floor slabs? (in the room, on the balcony, in the building corridor, etc.) regards...

Re: about slab loads

when i calculate my hollow slab load, it shows 0.684 tf/m2. when I try to right click on the slab and enter a "user defined" load, I enter 0.684 in the grab section, but in the plan view I enter G It looks like 0,872. Is this because it takes the entered user value only as a coating? Does it calculate the user value + program defined load (0.684+ approx. 0.2)? If so, should we enter the slab load we found by decreasing it by about 0.2?

Yes, you must enter other loads other than the self-weight.The self-weight is automatically added to the load you have defined.

that is, it only takes the 7 cm plate on the hollow blocks as its own load? does not calculate teeth, hollow blocks, plaster etc.? I thought it wasn't just calculating the weight of the hollow block. am i wrong

i.e. it only takes the 7 cm slab on the hollow blocks as its own load? It doesn't calculate the teeth, hollow blocks, plaster etc. I thought you were not just calculating the weight of the hollow blocks. Am I wrong?

You created the slab with the weight of the slab thickness You can see it on the plan at the moment. After the calculation of the self-weight of the teeth, the program automatically takes it into account. You will assign all other loads to the program, except for "teeth+floor self-weight", cladding+plaster+hollow brick etc.

first of all, thanks for your reply, i understand from your article As far as the floor (7cm) and teeth (25cm) are automatically detected by the program and we only have to enter bricks, plasters etc. but to try it out, I drew a non-ribbed floor, it showed G=0.188, I converted it to ribbed, the value was again G=0.188, I converted it to cassette, the value was again G=0.188 here is my conclusion; please correct me if I am wrong in calculating the teeth, regards

[as far as I understand from your article, the program automatically detects slabs (7cm) and teeth (25cm) and we only have to enter bricks, plasters, etc., but to try, I drew a ribless slab G=0.188 showed ribbed I converted the value to G=0.188 tape again. The value is again G=0.188 here is my conclusion; please correct me if I'm wrong in calculating the teeth, regards

Hello again, you're wrong. Tooth weights are not shown on the plan. If it were, I drew a ribless slab while showing G=0.188 I converted it to ribbed, the value was still G=0.188, I converted to cassette the value would still not show G=0.188. The weight of the 7 cm slab would be 0.07*2.5= 0.175 tf/m2. If you see G=0.188 tf/m2 on the plan, a 0.188-0.175=0.013 tf/m2 coating It means you have given the load.You can also see the tooth self-weight in the flooring report.

thanks, I understood the installations, I went to the flooring report for checking, I couldn't find the part you mentioned, but something else caught my attention, two lines are shown for the cassette, but only one of the slab fixed load (N3004, 1) is visible. Is there an error in my definition? I also saw that in the ribbed tile, the single tile is shown in separate rows. What is the reason? respects

The report you added is the report of the loads on the rib/cassette teeth. You wrote that the slab constant load appears only in one (N3004, 1), it is not, it appears in both. The reason why more than one line is seen is because there are teeth in the x and y directions on the cassette. If the fixed loads look different, the number of teeth in the x and y directions is not the same, the amount of load falling on a tooth varies for this reason. The part you can't find is in the flooring report.

The explanation is for the questions and sample values in the following screenshots: Answers to the questions: a. 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]B. For the cassette:[/u] If the value is 0.14 tf/m, the load distribution is made within a ratio depending on the tooth spacing, since the cassette has teeth in both directions. In the 1st direction, Ratio2 = CassetteBeamsRange D1 /(CassetteBeamsRange D1 + CassetteBeamsRange D2) In 2nd direction, Ratio1 = CassetteBeamsRange D2 /(CassetteBeamsRange D1 + CassetteBeamsRange D2) Ratio= 40/(40+40) = 0.5 (FixedLoadWeight) that you enter (CassetteBeamToothWidth w + CassetteBeams Spacing D2 * Ratio2)*1 (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*ConcreteUnitVolume*1 = (0.35-0.12)*0.1*2.5*1 = [color =#FF0000]0.0575 tf/m[/color] Total constant load = 0.135 + 0.0575 = 0.1925 tf/ m
