Project 1

Metro rail projects are necessary for metro cities. Its a only way to cope up with traffic jam and fastest comunication.

Here is a part of Ahmadabad metro rail project. Architectural drawings of Kankariya East station has been drawn. Before detailed drawing design is must for safety purpose. Data for design should be collected thoroughly. A Staad pro model is also given.

Dead Load

Verticle shear wall of reinforced concrete is 0.75m thick 10m wide and 20m high. Unit weight of concrete is 25.00kN/m3. So dead load will be 0.75m X 25kN/m3 = 18.75kN/m2, or 0.75m X 20m X 25 kN/m3 = 375.00kN/m. Total shear wall load will be 375.00 X 10 = 3750kN. For Two No of shear wall it will be 7500kN.

Roof slab of reinforced concrete is 1m thick 10m wide and 22m long. As the unit weight of reinforced concrete is 25 kN/m3 dead load will be 25kN/m2. Total load will be 10 X 22 X 25 = 5500kN

Plateform level slab is 2m thick 10m wide and 22m long. As the unit weight of reinforced concrete is 25 kN/m3 dead load will be 50kN/m2. Total load will be 11000kN

Concourse level slab is 1.2m thick 10m wide and 22m long. As the unit weight of reinforced concrete is 25 kN/m3 dead load will be 30kN/m2. Total load will be 6600kN

Plateform slab is 0.70m thick 10m wide and 13.5m long. As the unit weight of reinforced concrete is 25 kN/m3 dead load will be 17.5kN/m2. Total load will be2362.5kN

4No shear wall to support plateform deck is 0.60m thick 10m long and2.5m high. As the unit weight of reinforced concrete is 25 kN/m3 dead load will be 15kN/m2. Total load will be 1500kN

1No shear wall to gaurd is 0.60m thick 4.5m long and 2.0m high. As the unit weight of reinforced concrete is 25 kN/m3 dead load will be 15kN/m2. Total load will be 135kN

2No 10m long beam are of 2m X 0.75m. As the unit weight of reinforced concrete is 25 kN/m3 dead load will be 37.5kN/m. Total load will be 750kN.

Thus total load of structure will be 7500kN + 5500kN + 11000kN + 6600kN + 2362.5kN + 1500kN + 135kN + 750kN = 35347.5kN

IRS Live load for metro rail

Axle loading for each axle is 17t, Spacing in between end to first axle is 2150mm. Axle to 2nd adjusent axle 2200mm. Gap between first set up axle to 2nd set up 12400mm. Total length of car is 21100mm.

Earth pressure load

Verticle

Shear verticle wall is 18.5m below ground level, inner side is filled with soil 3.5m.

So P1 = 18 X 3.50m = 63.00kN/m2 and P2 = 18 X 18.5m = 333.00kN/m2

Horizontal

K1 = 0.35 X 18 X 3.5 = 22.05kN/m2

K2 = 0.5 X 18 X 18.5= 166.50kN/m2
