effective and can be successfully utilized for structural and non-structural applications in construction. Bamboo is one of the oldest traditional building materials. Bamboo building construction is characterized by a structural frame approach similar Bamboo has a long and well-established tradition as a building material . The aim of this publication is to offer a general intro- duction to bamboo as a construction material, with the key areas of preservation and jointing addressed in.
The the improvement in the economical aspect combined with construction activities in urban development have exploited ecological benefits. An engineered Bamboo can substitute the conventional resources of the mother earth and now the steel in making tensile stresses of RCC members and also trend is passing to the rural area too. From the beginning it reduces the consumption of cement in building. A traditional rural building is based on adaptations to the local Compared to urban areas, rural areas suffer more from the environment, and is often built with the labor of the villagers concentration of deprivation.
With incomes generally lower themselves without the need for external mechanized inputs.

This living in climatically suitable houses are all fine notions, but has implications for social sustainability of rural communities the durability of buildings is also an important consideration. There is a distinct lack of training maintenance, whereas a building with conventional materials and skill-enhancement in rural areas, not only for conventional like cement and steel is far sturdier, and has a longer life span.
This has adversely These conventional materials increase the overall cost of affected housing and building programs for all target groups construction . Providing construction guidance, and roof are made of materials that needs to be replaced information and counseling to local people will help in frequently in rural areas .
The use of these "cost-effective options" economic growth of common people. It is expected that large will change the negative perception of "low cost housing" eg.
Though the information in this regard has been Buildings with conventional materials like cement and steel developed, there has been a large gap in application. Therefore consume very large quantity of energy.
Why Bamboo is Used as a Building Material
Energy consumption access to building materials, technologies and construction in buildings occurs in five phases. The first phase corresponds delivery systems for cost effective construction activity is an to the manufacturing of building materials and components, important need in rural areas.
The second and third phases correspond to the energy used to transport materials The cost of construction is increasing by 50 per cent over the from production plants to the building site and the energy used normal inflation due to hike in the cost of basic building in the actual construction of the building, which is respectively materials and labor.
Consequently, even basic housing is now referred to as grey energy and induced energy. Fourthly, beyond the reach of a common person in rural areas. There is energy is consumed at the operational phase, which an imperative need to utilize technology options leading to corresponds to the running of the building when it is occupied.
Finally, energy is consumed in the demolition process of Although many attempts for evolving cost- effective buildings as well as in the recycling of their parts, when this is technologies have been made at the laboratory level by various promoted . Further, the 'awareness' Cost-effective construction technologies can bring down the level of these alternative and sustainable options has been embodied energy level associated with production of building minimal among users as well as professionals .
The existing materials by lowering use of energy-consuming materials. The construction practices in rural areas, using conventional cost-effective construction technologies would emerge as the options, lead to misuse of scarce and costly materials. Such most acceptable case of sustainable technologies in Rural practices have a larger environmental impact in terms of India both in terms of cost and environment.
The lack of support through building regulatory system is another factor that has Cost-effective construction technologies, which apart from inhibited the use of cost effective options in construction reducing cost of construction by reduction of quantity of sector of rural areas. As a cumulative effect, the building building materials through improved and innovative structures offered to the rural people are either expensive and techniques or use of alternate low-energy consuming Journal of Civil Engineering and Environmental Technology Print ISSN: ; Online ISSN: X; Volume 1, Number 6; August, Bamboo as a Cost Effective Building Material for Rural Construction 37 materials, can play a great role in reduction of CO2 emission Bamboo Bambuseae is a tribe of flowering perennial and thus help in the protection of the environment.
Giant bamboos are the Bamboo is one such material, which can be used by the rural largest members of the grass family. In bamboos, the community in their construction, which has extensive potential internodal regions of the stem are hollow and the vascular in building industry when supported with required treatment bundles in the cross section are scattered throughout the stem and trained workers.
The dicotyledonous woody xylem is also absent. The absence of secondary growth 4. Bamboos are The majority of bamboo construction relates to the rural some of the fastest-growing plants in the world, due to a community needs in developing countries.
It is mainly used in unique rhizome-dependent system. More than 10 genera are housing but other common types of construction include divided into about 1, species . Further applications of bamboo relevant to construction include its use Characterized by the type of rhizome and the formation of as scaffolding, water piping and as shuttering and upright canes there are three main groups of bamboo. The first reinforcement for concrete. They form long and thin extensions of the rhizome whose buds produce single shoots Bamboo has historically been used as a building material due are regular intervals.
The sympodial bamboos constitute the to its inherent properties, being regenerating, biodegradable, second group. They have short, thick rootstocks the tips of with high tensile strength, and lightweight. However, despite which produce the canes. The third group is called climbing its innumerable qualities one does not get to see bamboo as bamboos.
They can grow very irregularly and may form popular building material. Bamboo reinforced Concrete for the impenetrable thickets. Like the grasses they productivity and cycle of annual harvest outstrips any other have tubular blades, lancet-shaped cover leaves and panicular naturally growing resource, if today we plant three or four flowers and from a subterranean rootstock branch extensively structural bamboo plants, then in four or five years later we to form dense to loose bushes.
The following characteristics will have mature clumps, and in eight years we will have distinguish bamboos from grasses: the longevity of their enough mature material to build a comfortable, low cost canes, their branching and the lignification.
Like leaf bearing structure . Emerging Main characteristic features, which make bamboo as a with its definitive circumference from the soil without potential building material, are its high tensile strength and increasing in diameter later. The strength-weight ratio of bamboo also 4.
Above all It has also been found that bamboo acts very well in buckling bamboo is renewable raw material resource from agro-forestry due to low stresses than compared to steel. The dark spots, decreasing from left to right in the cross-section, are cellulose fibers together with Manuscript received November 12, The material between plastic.
Rays are places for the transport and storage of food, mostly sugar, but they weaken the material. Consequently, bamboo is stronger than wood, especially in shear. However can one expect bamboo to be as economically competitive?
A simple calculation will explain this.
However, wood used for beams costs much more than this, emphasizing the competitiveness of bamboo in structural use. When considering a material for structural use, the first question that arises is about its safety.
To make stresses between these different materials comparable, the value of the stress in the material when the building is in normal use is taken as the unit. This is Fig. In each of the three diagrams in Fig.
The lowest diagram is for steel, a material that is produced using a very Fig. The diagram in the creates is ten percent more than the one that a more even middle for wood and bamboo, which are natural materials, distribution pattern could offer — an excellent example of the shows a wide variety of stresses around the mean stress at structural design acumen of Mother Nature imagine a steel failure.
In these materials, specimen quality varies widely tube with high tensile steel on the outside and normal mild from very bad to very good.
Because of this uncertainty, one steel on the inside! The vessels take care of the transport of finds a large distance between the stress at failure and the 46 www. The use of timber If we take for d the value of 0. In the case of a disaster like a hurricane or an earthquake, however, the stresses will get multiplied. They In a similar way we get for A the value 0. We need a may become double the allowable stress. In such cases, stresses in steel will come into the area of failure, but not in comparison between I and A, but I is related to and A to timber and bamboo.
This means that steel structures will. Another comparison between the materials is shown in difference of 2. If numerical values, D Fig. Steel is the best and bamboo the second best.
In both cases, the value of I Moment of Inertia for timber is much less than that for bamboo. This indicates that the structural efficiency of bamboo is very good. This brings up IV.
Construction and Building Materials
The tube material they are accustomed to is the steel tube, which is very expensive. Consequently, engineers always use I-shaped profiles for beams. As can be seen, the bamboo I-Profile on the left is hollow tube, while the timber on the right has a Now consider Fig. How do their respective structures affect culm is on the left.
Imagine that the material from both sides the efficiency of these materials? Or, expressed in technical are pushed horizontally towards the vertical axis of terms, what effect does this structural difference mean for the symmetry, and see what happens. The result is something ratio between the moment of inertia I and the cross about the same as a steel beam profile!

The distribution of these fibers increases from the inside to the outside. In most bamboos, fibers corner and in the plane of the wall.
The results were more than satisfactory. Bamboo as a reinforcement in concrete structures has not been employed to the satisfying proportions till date. Is bending strength determined by bending stress orby shear? The bamboo as a reinforcement has been found to have the This depends on the length of the free span: in case of a short following mechanical properties free span, the bamboo does not act as a beam but as an arch,. If the free span is long, and if a four-point bending test is being run, pure Mechanical Property Value bending stresses will determine the strength.
Evidently, there mpa must be a boundary below which shear is the limit and above Ultimate compressive Ultimate tensile strength Many misunderstandings follow from a lack of In a real bending test, the nodes with the diaphragms act like a plastic hinge, resulting in Allowable bond stress 0.
But in a test with a short free span, they strengthen the arch-like behavior of the beam, resulting in less Modulus of elasticity Several researchers have come to wrong conclusions because they were unaware of this.
Bending tests Fig. These For bamboo reinforced concrete beams, the deformation is saddles should rest on the nodes, to avoid crushing of the approximately half that of steel. The allowable bending internodes. In bamboo reinforced concrete, bamboo shrinks more than Consequently, most of the time, the outcome was concrete as it loses moisture, completely breaking any bond disappointing.Seminars Topics.
The fibres of bamboo run axial. This research can help in deciding the use of Bamboo as a Structural and Constructional material in Buildings. Authors are also requested to name five independent referees together with institutional email addresses.
Imaginative possess .
With proper engineering, bamboo in combination with modern material technology as a use of Bamboo in building can aid in the growth of alternative building material in rural construction. Most bamboos non-timber forest resources due to the high socio-economic are hollow.
