Masonry
It is mainly used for load bearing walls
taking vertical and horizontal loads. It can be used for buildings up to 20
storeys. But unfortunately here the quality of masonry is not up to that
standard. So 2 or 3 storeys can be done.
Reinforced and Prestressed Concrete
RCC if properly handled good for shear wall
construction is very durable and fire resistant. RCC can be cast to any
required shape. It is used for a variety of construction including tall
buildings. Prestressed concrete is used for large span buildings ,bridges and
towers.
Good quality control is not given to RCC
structures so in India resulted in failures in earth quakes. But quality of
prestressed concrete is come to the standard in india because major companies
are using it.
Structural Steel
Its main advantages are strength speed of
erection and prefabrication. It is used in buildings bridges trusses and space
frames. Steel requires fire and corrosion protection. In steel buildings foundation
s are done by concrete walls and claddings with masonry or other materials. Steel
structures are done in workshops and assembled at site is better in quality but
requires good workmanship. Welding must be of good quality. Steel offers good
compressive and tensile strength so lighter structure is the result. Main
advantage is it can be recycled.
Wood
It is used for up to 3 floors. It gives
warmth what steel and concrete lacks.
Wood has long been used in western countries and in Japan in historical
structures. Wooden domes are done in USA and Japan which diameter is 160-180m.
In India wood is used in windows and doors. Treated rubber is good for
furnitures and for small building roofs.
