Abstract – Reinforcing steel, used in reinforced concrete
ductility is achieved through concrete crushing [2], or the limit of working stress needs to be kept lower than that of ultimate strength such that reinforced section provides clear information before it goes to failure. The average tensile modulus of Gudua Angustifolia type bamboo is on the order of 20 GPA[3], thus the modular ratio Esteel/EBamboo =10.
worldwide, is expensive. As a result, there is a proposal to use bamboo as a reinforcement in concrete, in the form of culms or strips. Bamboo is a highly renewable and versatile resource, characterized by high strength and low weight, and is easily accessible using simple tools. Numerous studies are being conducted on the productivity and usage of bamboo as a reinforcement. This research paper specifically focuses on the performance of bamboo as a structural reinforcement for fivestory buildings under earthquake conditions. The necessary inputs for this research were obtained from experiments and used in the ETABS software to analyze earthquake cases.
2. PROPERTIES OF BAMBOO 2.1 Physical Structure of Bamboo Bamboo is most compared with wooden products because of its similar chemical structure. However, the physical structure of Bamboo is not the same as other wooden members. Wooden products have anisotropic properties, and they contain grains that are oriented in the same direction throughout the complete structure. On the exterior edge of every node, branches form different types of leaf structures that look like grass. Bamboo has parallel fibers that are reinforced along the axial direction of the Culm.

1. INTRODUCTION Generally, reinforcing steel is used as a rebar material for construction. However, due to rising concerns about energy and the environment, searches are going on for non-polluting materials that need less energy. Finding a substitute using all types of waste or fiber is being developed. In this era, the choices of people are categorized on price and quality, but due to lack of awareness and knowledge about available materials, forces people to use industrialized materials. While manufacturing 1kg of steel produces 1.85 tons of carbon dioxide, almost 8 percent of global carbon dioxide emission, while Bamboo emits only 80 times less carbon dioxide. Steel carbon footprints are 2.2-2.8 kg CO2/kg and 0.25 kg CO2 /kg for Bamboo. Talking about its mechanical properties, the tensile strength of Bamboo is quite high, and its specific weight is comparatively higher than that of steel, making it an attractive substitute for steel. For Bamboo, the tensile strength-to-specific weight ratio is six times greater than that of steel. [1].
2.2 Shrinkage and Swelling Bamboo behaves the same as wood and changes its dimension when it loses or gains moisture content. Bamboo is categorized into hygroscopic type material. The moisture content usually changes with having change in the corresponding humidity and temperature of the surrounding atmosphere[4].
2.3 Bending B Bending is the most important parameter as it is directly related to the material’s initial and ultimate strength. The bending property of any member is mostly dependent upon its cross size. Because of this ability, Bamboo can be treated as a substitute for reinforced steel in the construction of buildings[4].

2.4 Elasticity
Generally, it is a common practice that an underreinforced concrete section is preferred for a design in which reinforcing materials yield first that of concrete material which helps to inform the occupants that the building is going to have failure soon. Bamboo is also a brittle type of reinforcing material and failure is not acceptable, either an over-reinforced design is prescribed by which limited

The enormous elasticity of Bamboo material makes it a very good building material for earthquake-prone areas. Also, Bamboo has very low weight. This helps for smooth transport and works easily, thus the use of cranes and other big machines becomes unnecessary[4].
