“…However, reliable quantification of its tensile strength is problematic as it is naturally occurring, therefore giving bamboo a wide variability in strength. Therefore, studies on its performance have mainly aimed at finding the optimum percentage of reinforcement that gives a maximum level of ductility under loading. Khare recommended that an optimum of 4% longitudinal reinforcement should be utilized in the design of bamboo‐reinforced concrete structure, in order to maintain an appreciable ductile behavior before ultimate failure.…”

The use of bamboo as longitudinal reinforcement, coupled with the application of self-compacted concrete (SCC) in the construction industry, may be a promising solution to issues involving sustainable development in developing countries. This study seeks to investigate the flexural performance of bamboo-reinforced SCC beams with adequate transverse reinforcement. The major design parameters were the shear span-to-depth ratio, the percentage of longitudinal reinforcement, and the maximum size of coarse aggregate. The load-deflection curves, serviceability and ultimate failure characteristics, cracking behavior, and ductility measures were evaluated and discussed among tested beams. Results indicated that their structural performance at service and ultimate failure would be adequate when a material reduction factor of three is used with BS 8110 design code. However, to achieve maximum ductility, the level of longitudinal reinforcement should be in range of 2.6-3.1%. Furthermore, an increase in the size of coarse aggregate will greatly impact the degree of ductility.

Hence, to maintain a sustainable construction industry, several innovative studies have investigated the relative performance of alternative design methods and materials to conventional ideologies. [1][2][3][4] Javadian et al 5 noted that the contribution from developing countries to the overall demand on concrete as a building material is approximately 90%. Additionally, Hebel et al 6 established that developing countries also account for about 80% of the global demand of steel in the construction industry. However, most of such countries are unable to synthesize these materials, particularly cement and steel, and rely heavily on importation from others. Hence, alternative building materials, which are readily available, affordable, and able to exhibit adequate structural behavior under all forms of external loading, are greatly preferred.A suitable option will be to use bamboo as longitudinal reinforcement for concrete structures that are not subjected to severe loading conditions. Extensive researches 3,4,7-10 on the mechanical behavior of bamboo have revealed that it possesses a comparable tensile strength in relation to mild steel and, as such, can serve as a suitable replacement for steel. However, reliable quantification of its tensile strength is problematic as it is naturally occurring, therefore giving bamboo a wide variability in strength. Therefore, studies 3,4,11,12 on its performance have mainly aimed at finding the optimum percentage of reinforcement that gives a maximum level of ductility under loading. Khare 13 recommended that an optimum of 4% longitudinal reinforcement should be utilized in the design of bamboo-reinforced concrete st...

“…The research into the reduction of environmental impact and/or the use of cheap or recycled materials [ 12 ] represent viable ways to find low-cost structural solutions. Natural reinforcing materials were coupled with concrete to analyze the increase in strength and sustainability [ 13 , 14 , 15 ]. New biocomposite materials with bamboo strips [ 16 ] and composed bamboo elements [ 17 ] were proposed to extend the traditional use in scaffolding [ 18 ] to structural applications.…”

Experimental tests and constructive assessments are presented for a simple bamboo framed structure with innovative low-cost and low technology joints, specifically conceived for small buildings in developing countries. Two full scale one-storey bamboo frames have been designed by using the simplest joints solution among three different tested typologies. The entire building process is based on low-technology and natural materials: bamboo canes, wooden cylinders, plywood plates and canapé rods. The first full scale specimen (Unit A) is a one-storey single deck truss structure subjected to monotonic collapse test; the second full scale specimen (Unit B) is a one-storey double deck truss structure used to evaluate the construction time throughout assembling tests. The first full scale specimen showed ductility in collapse and ease in strengthening; the second one showed remarkable ease and speed in assembling structural elements. Finally several constructive solutions are suggested for the design of simple one-storey buildings; they are addressed to four purposes (housing, school, chapel, health center) by the composition of the proposed full scale bamboo frames. Ease of use and maintenance with a low level of technology contribute to application in developing countries although not exclusively.

This study aims to evaluate the performance of Landolphia buchananii shear reinforced concrete beams to establish the potential of Landolphia buchananii as a shear reinforcement of concrete beams. Tensile strength test on Landolphia buchananii was performed and reinforced concrete beam test was done. The performance of Landolphia buchananii shear reinforced concrete beam was compared to that of steel shear reinforced concrete beam. Varying size/area of shear reinforcement of Landolphia buchananii was used for beam specimen made of concrete of average compressive strength of 20.8 N/mm 2 . The results showed that the failure loads increased with increase in area/size of shear reinforcement. Tensile strength of Landolphia buchananii was found to be 65 percent lower than that of conventional mild steel. The study showed that Landolphia buchananii can be used as shear reinforcement in concrete beams and can be used as a substitute of steel under low loading regimes.
