How to calculate DEAD LOAD of SLAB


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
