PREFABRICATED COMPONENTS.

1.LONG WALL SYSTEM :

The main beam (or) load bearing wall are placed to the long axis of building . it is applied to the building with large prefabricated and similar to traditional brickwork . The longitudinal wall crosses the floor load must posses not only thermal .

2.             How are roofing members in prefabricates classified ?

Ø  Small roofing members.

Ø  Large roofing members.

Ø  Reinforced planks (or) ties .

Ø  Light weight concrete roofing members .

Ø  Small reinforced concrete roofing members .

Ø  Purlins .

3.             How are the prefabricated component classified ?

a) Based on the area (or ) size of prefabricates

. b) Based on weight of prefabricates .

c) Based on the

function . d) Based on

the shape .

e) Based on the material .

4.What are the space bordering ?

These members are used to give spaces like walls both load carrying and partition walls . this may (or ) may not contain doors and windows the provision for the same is as per the requirement . Another example for the space bordering member are floor slabs .

5. What is the meant by surface forming members ?

In the case of surface forming members, the load carrying and surface bordering are united and a uniform load carrying surface is found loaded by complex forces and economic shapes.

Example : Shell structures folded plates structures etc.

6. differentiate  between synclastic  and  Anticlastic  .

In the case the synclastic the curve of the shell in the same side (eg : hemispherical shell ) where as in the case of anticlastic the curvature of the shell is in opposite direction eg: hyperbolic shell (saddle shell ).

7. Write a short on dome structure .

A dome is a space structure covering a more (or ) less square (or ) irregular area . The best known example is the dome of revolution , and it is one of the earliest of the shell structure.

Excellent examples are still is existence that were built in Roman times .

8. Define shear wall .

These are simple type and these shear walls under forces and horizontal shear along its length are subjected to bending and shear walls.

To resist these forces , the uniform distribution of steel along its length is used in simple shear

9.             Different classification of shear walls .

1)Plain rectangular shear wall

2)Bar bell type .

3)Framed shear wall .

4)Coupled shear  wall.

5)Care type .

10). What is ring system ?

# Load bearing walls and beams are placed in both ways longitudinally and transversely . In the building with ring system of support floors are normally supported on all four edges and span is two direction .

In skeleton construction these floors are placed directly on columns .
