Hence, this study aimed to look for a solution to <br>address these challenges. This study investigated, both qualitatively and quantitatively, three testing protocols <br>in determining bamboo’s tensile strength parallel to fiber – (1) ISO 22157, (2) a modification of ASTM D143, <br>and (3) Pittsburgh Method. The success rate, test duration, load rate and transmission, specimen preparation, <br>equipment fabrication, and execution of the three protocols were compared. The physical properties of <br>bamboos, such as moisture content, density, and shrinkage, were also measured in the study. The results of the <br>study showed that the modified ASTM D143 test is the most viable method to use in testing the tensile strength <br>parallel to fiber of bamboos. Modified ASTM D143 produced the highest tensile strength with value equal to <br>100.36 MPa, compared to specimens tested under ISO 22157 with tensile strength only reaching 94.11 MPa, <br>while Pittsburgh Test produced the lowest tensile strength of 76.78 MPa. Modified ASTM D143 also yielded <br>the lowest confidence interval which implied good consistency. Modified ASTM D143 is the recommended <br>test protocol based on the results of this study as it gained the highest success rate during testing, lowest testing <br>duration and the easiest to execute.</p>}, number={74}, journal={GEOMATE Journal}, author={Martin De La Cruz and Luis Lopez and Richard De Jesus and Lessandro Garciano}, year={2020}, month={Oct.}, pages={31–36} }
