Hey guys welcome back to my channel, In this

video i am going to teach you the very basic thing,

THAT “HOW CAN WE CALCULATE THE DEAD LOAD OF SLAB” OK. Since, all of us know that density=mass/

volume therefore, mass=density x volume ok.

we can calculate the dead load of slab in three different forms

1. dead load per unit area the second form is

total dead load on slab and we can calculate the dead load in the form of UDL, in order

to calculate the bending moment ok!. Assume the thickness of slab if it is not

given. In our case we have 150mm as thickness of

slab. You can findout the deadload per unit area

since, density of the RCC is known. Dead load of slab can be finout by density

multiplied by slab thickness. therefore, multiply these two values, 2500*0.150

then you will get it as 375 kg per meter square. This dead load is per m^2 ok!. Here we are interested in finding out the

total dead load of the slab. Total dead load of the slab can be find out

by mass=density x volume. we know the thickness of slab, we know the

width of the slab and we know the length of the slab. so, area can be find out by multiplying

width and length. 6 x8=48 m^2.

if you multiply area with thickness of the slab then you will get volume ok!. Here, 0.15 x 48 this is the volume of the

slab. voulme is multiplied by density which gives

us mass. so, total dead load=2500 x 0.15 x48=1800

KG. Generally we calculate the dead load in the

form of udl to findout the bending moment. so, to calculate the dead load in the form

of udl we must know the effective span of the slab. Assume the effective span of slab as 6m. Therefore, udl=total dead load of the slab

divide it by 6 i.e., effective span. Dead load in the form of udl=total dead

load / effective span. which gives us 300kg /m ok!

this is in the form of udl. dead load is also can know as self weight

ok! don’t get confuse between self weight and

dead load
