A two-way reinforced concrete building floor system is composed of slab panels measuring

6\times 7.5m

in plan, supported by shallow column-line beams cast monolithically with the slab as shown. The slab is assumed to have a thickness of

180mm

. The beam dimensions

350\times 500mm

will be assumed. Design the exterior panel to carry a live load of

7k(N)/(m^(2))

in addition to the self-weight of the floor. Use

f

'

c=28

MPa,fy=420MPa

. Slap

=6\times 7.5(m)/(h)=180m(m)/()

Beam

=500\times (350)/()

L*L=7k(N)/(m^(2))+

self weigh of floor

/P_(-C^('))=28\mu p(a)/(f)g

exterior Beam:-

(a)

I_(b)=1.5I_(D)=1.5((300(500)^(3))/(12))=>I_(b)=5.46\times 10^(9)mm^(47)

interior Beam:-
