Contemporary Wooden Staircase Designs

Wooden Staircase Designs - Well, so today we shall learn how to design stair cases. So, far we have done design of slabs, design of beams, design of columns and design of footings. So, one of the important element for the in any building or structure that is stair cases, because that one only will help us to go from one floor to another floor. You will find out different kind of stair cases. We can say this is our that lecture number 26, which we are going to deliver on the design of stair cases. This one type of stair case, you will not find out merely, but this is one type sometimes even in our campus also we can find out few of them. This is the same view; the different view of the same structure. So, here you can find out as if the stair case, you can say as if the bricks one after another it is just kept and you are going from the one floor to another floor.

This is another type, compare to the other one you can see another type. Here, wooden staircase paint ideas I think I can show you. This is your stapes and were you can find outthe beam, in the back there is a beam and these beam is supporting and I think the last view will be better, yes here there is the beam here and over that all the steps are supported. So; obviously, the past one which I have shown there is one kind and this another one kind of stair cases, which is supported by the beam and over that your steps are there. In that steps you can say easier can cantilever beam again. So, that you can design. But the most popular one. So, this the other view this 1, we will find out most of the design you will find out this type of stair case, this is the most popular 1 and we shall design this 1. But I shall tell you that how to design the other stair cases also. What you have to find out, what you have to do for any stair case what you have to do and you have find out what is the governing, 1 the bending moment how it is acting about which axis and then according to that you have to design as well as shear force also.

So, this is your 1. So, you can say this portion is continually work, wooden staircase handle designs this is 1 column and this is another column, which is supported by the 2 beams; 1 this side and this side and this slab, this is the 1 you have. I think that is all I have the photograph so for concern. So, but I can say here; there is 1 stap here, you can see those staple all the steps. So, you have to consider the dead load of the steps also, weight of the steps also and this is called waist slab. So, how to design this 1; if you like to say that I should not consider this, the last 1 I have told the steps 1 after another, but here we are assuming this stapes are supported by this slab. So; that means, I can design that slab. If I know draw that figure we can say; so this is your slab which we have to design. Over that, you have these steps, these are the steps. So, what we have to do; we have to design what about this depth, this is called waist. There are two things: 1 is called rise R and this is called tread T. So, we have if we make it very very different one, in the sense, I can write like this, sometimes we can project little bit; so let us make it some kind of projection and then I can go again this kind of steps. Yes like that it will go. So, if we move and then you have; it is supported these steps are supported by this slab.
