Slide 2:
Example 1
Calculate the dead load of a R.C.C. beam
Size of the beam is 23 X 30 cm. Length of the beam is 5.0mt.
Calculate the dead load of beam
Slide 3:
Example 2
Calculate the dead load of a Steel beam
Size of the beam is 30 cm. diameter round pipe 6mm thick
Length of the beam is 5.0mt.
Calculate the dead load of beam
Slide 4:
Example 3
Calculate the dead load of a R.C.C. slab
Size of the Slab is 3.0mt by 5.0 mt., Thick ness is 12 cm.
Calculate the dead load of slab
Slide 5:
LIVE LOAD
Let us calculate the Live load on structure
We have to refer the International building codes for live load
Live load is as per the usage of the building.
Slide 6:
Example 4
Calculate the live load of a R.C.C. slab
Size of the Slab is 3.0mt by 5.0 mt., Thickness is 12 cm.
Calculate the live load on slab for residential building.
Slide 7:
Example 5
Calculate the live load of a R.C.C. slab
Size of the Slab is 3.0mt by 5.0 mt., Thickness is 12 cm.
Calculate the live load on slab for school building.
Slide 8:
Spanning systems of R.C.C. Slab One-way slabs
One way slabs are spanning in one direction, Suitable for 1.8 to 5.0 MT.
Also suitable for moderate loads
One way slabs are supported by concrete beams or load bearing walls
In short direction
Two–way slabs
Two way slabs are spanning in two direction,
Suitable for medium spans and heavy loads
When we transfer the load of slab
it should be transferred in one way slab
to adjoining longer side of wall or beam half –half
it should be transferred in two way slab
on all four sides of wall or beam.
