“…Compared to boron treatment, using copper chrome boron (CCB) preservatives resulted in a higher Modulus of Rupture (MoR) and CS for the treated bamboo. This indicates a positive influence on the suitability of bamboo, especially in structural applications [14]. Scanning electron microscopy (SEM)-energy dispersive X-ray (EDX) analysis revealed that an increase in bamboo fiber content without a corresponding increase in natural rubber latex content resulted in the formation of void spaces within the concrete.…”

Bamboo holds significant global economic importance as a non-timber forest product. Its fibers can be utilized in concrete reinforcement, a concept known as bamboo fiber reinforced concrete. Nevertheless, further investigation is required for Bamboo Fiber Reinforced Concrete, with a specific focus on bamboo tensile strength. This study aimed to foretell the BTS through several machine learning techniques, including artificial neural network, extreme learning machine, and support vector regression. A total of 30 samples from the previous literature article were considered for predicting Bamboo Tensile Strength. The dataset was split into two parts, with 80% allocated for training data and 20% for testing data. The outcome from the data testing shows that the extreme learning machine predict very sensitive to random errors in the observed target. The results show that a positive correlation was found between key input parameters, such as the shorter dimension of bamboo, the longer dimension of bamboo, cross- sectional area, modulus of elasticity, and area, in relation to the output bamboo tensile strength.

This study investigates the influence of varying concentrations of boric acid (BA) preservative on the physical and mechanical properties of light red meranti (LRM) found in Sarawak. LRM or Shorea leprosula samples were treated with various concentrations of BA via the dip diffusion method using American Society for Testing and Materials (ASTM) standards. The physical property, particularly the retention rate and mechanical properties, bending strength, modulus of elasticity (MOE), tensile and compression strength parallel to grain of impregnated and control samples were tested to determine the effects of BA preservative. The retention rate was found to increase with increasing BA concentration and higher surface area to volume ratio. The mechanical properties in terms of the MOE and tensile strength parallel to grain were found to be greater than those of the control samples, whereas the bending strength and tensile strength parallel to grain were lower. Amongst the results, only the retention rate and MOE showed significant interaction effects at 5% level of significance between all factors tested (samples size and BA concentration for retention rate and BA concentration for MOE).

“…The cavities in the bamboo trunk separated by membranes and called nodes. The internode length of bamboo varies, and the intermediate internodes are longer than the base and shoot apex, as in [1], [2], [3], [4], and [5]. Fasteners transmit shear forces and prevent or reduce movement between bamboo and concrete panels.…”

Bamboo ropes assembled in parallel and filled with mortar to create a composite structure. This study uses fixed loads and uses the EYM method. The purpose of this study is to investigate how connection strength, maximum load and stiffness values in normal weight concrete. The concrete design 25MPa used for threaded connections with diameters of 6 mm, 8 mm, and length of 40 cm. This study provides a maximum stress analysis of bolted joint strength and joint behavior. In this test, the study yielded a P-max value of 88.25kN at 6 mm diameter and a P min value of 16.87kN at 6 mm diameter for each variation of the sample. The P-Max value for 8 mm diameter is 29.71kN and the P-Min value for 8 mm diameter is 10.1kN. The stiffness values for each variant with a K-Max value of 41.53kN for diameter six and a K-Min value of 0.96kN for diameter six are 1.98kN K-Max value and 1.98kN K-Min value for diameter 8 mm, 0.21kN for diameter eight. The lateral resistance gives the same result of 8.8kN as for the ones melting point model. The maximum value of the pivot strength at 6 mm diameter and 40% load is 41.53kN/mm2. The highest value of the 40% load test with a diameter of 8 mm is 1.98kN/mm2. Two angle variations used in the test: 45° and 60°. The angular change of the sample damaged during the test was 60°, and the sample damage was 8 mm in diameter.
