Dr.Structure, the equation used @7:39 should be x=L/2 + (L/6)((a-b)/(b+a)).

@DrStructure 6 жыл бұрын

b is the taller side of the trapezoid. If b is significantly larger than a (the shorter side of the trapezoid) then your equation could result in a negative value for x, since (a-b) becomes a large negative number. But we know that x cannot be negative given that it is the distance from the left end of the beam. How do you explain that?

sir I have a doubt initially you have told that load is distributed as surface distributed load and one dimensional distributed load... later you have considered the load as trapezoidal load from slab ( VIDEO NO SA34 LECTURER) I have a little bit confusion in that what is the difference between initially you have told about surface distributed, one dimensional load and trapezoidal load of the two way slab... plz kindly reply sir

@DrStructure 7 жыл бұрын

Thanks for the question. There is no discrepancy between the two explanations. A load that is distributed over a surface often needs to be translated into a line load. The shape of the line load depends on the geometry of the surface and the load pattern on the surface. Let's limit our discussion to rectangular slabs. If the slab is supported by four beams on its edges, then depending on the dimensions of the slab (whether we have one-way slab or two-way slab) we get a different load pattern on the beam. Say, the surface load is uniformly distributed, then if the slab is one-way, the line load would also be uniformly distributed. But if the slab is two-way, the line load would be trapezoidal because of the Yield Line Theory, as is indicated in SA43. Now, let's consider a non-uniform surface load. Let's say there is snow on the roof, and the distribution of the snow is not uniform, there is a bigger pile of snow at one end of the roof creating a rectangular profile. If the roof is a one-way slab, then the line load due to the surface load is also going to be triangular. If the surface load had a trapezoidal profile, the line load would also be trapezoidal. So, the trapezoidal shape of the line load (on the beam) could be due to the load profile on the roof, or it could be due to the fact that we have a two-way slab.

Dr. Structure sir yes now i understood very clearly how does load transmitted to the beam from your explanation . Awesome....

Nice video, I want to convert a slab load (kN/m2) into beam load (kN/m), is there any video I can visit?

We don't have a video that deals specifically with the case you've mentioned.

Ok, it's alright. I think the method name is envelope method. I have surfed on the internet but I found some different types of equations. Still confused where is the right equation.

Dr . Structure, 6.59 Is it equal 2×12=24 ?

@DrStructure 6 жыл бұрын

If the 2 in your equation is the average of the heights of the trapezoid, then yes! :) The area of a trapezoid equals to the average of its two heights times its base.
