Abstract: This study discusses the results of experiments on flexural strength of the concrete beams using bambo strip notch as reinforcement, with variations in the distance between the notch at 40 mm and 50 mm. The flexural parameters assessed were the flexural moments and load-deflection behaviour. The number of concrete beams specimen was 9 units. One sets for 3 beams containing round steel 8 mm as reinforcement and two sets of 6 beams containing bamboo as reinforcement were tested for flexural strength under third point loading. All beam specimens size is 110x150x1700 mm. The data recorded while tested the flexure were a failure load, deflection and failure models. The failure loads of beams increased with increase in the number of notches bamboo strip in the tensile zone. The ultimate moment experimental and theoretical of bamboo strip notched concrete beams increased, with increase the number of notches bamboo strip in the tensile zone. Thus it can be concluded that inclusion of bamboo strip notches as reinforcement in tension zone improved the flexural capacity of concrete beams.

Abstract: In this study, the classification of modes of failure, the observation of microscopic failures and the mechanical properties of Semantan bamboo strips were investigated. Specimens were loaded in bending and shear parallel to grain. Specimens were taken from internodes and node parts in bottom, middle and top portions of bamboo culms. From the classification, different modes of failure occurred in different parts of Semantan bamboo culms loaded in bending and shear. From the microscopic observation, the failures occurred in both parenchyma and vascular bundles regions for all classified failure modes from all tests, except for Even Splitting Mode from shear. This mode exhibited failure in parenchyma only, without any failure in vascular bundles regions. The Maximum Stress (σml) values between failure modes for both tests were significantly different. Generally, anatomical behaviour at different culm’s parts had influenced the different modes of failure and microscopic failures of Semantan bamboo strips loaded in bending and shear.
