STUDY OF BAMBOO

STRUCTURES IN NAGPUR CITY

(LIVE CASE STUDY)GROUP 1

introduction

Advanced Construction Studio-I Semester VII

• Bamboo is a versatile, strong, renewable and environmentally friendly material.

• A member of the grass family, subfamily Bambusoideae, it is the fastest growing woody plant producing a mature fibre for use within three years.

• Bamboo has been traditionally used as a building material and in present times used in low cost housing, building temporary structures and other indigenous architectural expressions.

Advanced Construction Studio-I Semester VII

•Bamboo is an extremely strong fiber with twice the compressive strength of concrete, and roughly the same strength to weight ratio of steel in tension.

•Abundant, sustainable, and extremely resilient, bamboo has potential in the future to become an ideal replacement in places where steel cannot easily be produced.

•The structural advantages of bamboo are its strength and light weight whereby properly constructed bamboo buildings are inherently resistant to wind and earthquakes.

USAGE IN STRUCTURE• Roof Truss

• Columns

• Beams

• Fencing

• Bracing

• Binders

•Foundation

Advanced Construction Studio-I Semester VII

foundation• Bamboo is used foundation as reinforcement for

concrete.

• It is used in two ways: (i) single post footing and (ii) strip footing

Advanced Construction Studio-I Semester VII

columns• Columns are made of

bamboo used as vertical posts in

combination of two, connected by cross bracing inside and screwed with long

nuts and bolts.

Advanced Construction Studio-I Semester VII

Columns

• Sectional plan showing the through nut and

bolts, bamboo vertically used in combination od

two and horizontal binding member.

• The sketch shows the

typical column on the pavilion

with all its constituting

elements. The column is

embedded into the concrete

floor and attached to the

roof truss above.

Advanced Construction Studio-I Semester VII

Columns to roof • Columns are connected roof beams and

roof trusses which support the fibre material roof sheets. These are joined

through screws and bolts.

Advanced Construction Studio-I Semester VII

Columns to roof

• The sketch shows the bamboo column

connection with the roof rafters. The rafters are in a combination of two

and braced. The connections are done using nuts and bolts.

Roof truss • The roof truss is made of

inclined bamboo primary members (approx. angle of

45 degrees), bamboo rafters, horizontal bamboo binders and angle cleats.

Truss to roof cover• The roof truss is connected to the plywood pelmet through angle

cleats bolted into place.

• The horizontal beams in the roof truss support the fibre board roof

covering and are joint using j-bolts.

Advanced Construction Studio-I Semester VII

Electrical• Electrical wires have been concealed

within PVC pipes which are placed alongside the horizontal members for supporting the roof covering of Fibre

board.• Switchboards are provided at two

diagonal ends and tube lights are provided.

Advanced Construction Studio-I Semester VII

Bamboo connections• Plugin connection is

used in bamboo structures.

• This is a type of connection for greater diameters with long bolts and ring/plate.
