This study mainly focusing on to reduce the cost of materials which are utilized for construction purpose particularly steel. Steel is the material which is used for all types of reinforcement in column, beam and slab. The main disadvantage of this material that it easily corrodes when it interacts with moisture and due to this effect, its strength is also greatly reduced and it leads to durability problem in buildings. For reducing this effect, we utilize the bamboo rebars as a reinforcement in the place of steel for not only to increase durability property but also to enhance the utilization of low-cost and efficient materials for construction purpose. The bamboo can be replaced in structural member with certain percentages such as 25 %, 50 %, 75 % and 100% as a main rebars. The bamboo rebars were placed in both tension and compression zone on 0.7 m beams. The beams are tested under loading frame and test results are obtained. In loading frame, two-point loads were given in one-third of position on both ends in beam. From the test result, it was compared with conventional beam in flexural strength, deflection and their crack pattern and it shows that 25 % bamboo replacement beam obtain greater strength than other percentage of bamboo beams. From our research, we recommend that bamboo can also be utilized in members instead of steel in structural members. © BEIESP.
