Regression Analysis of Bending Perpendicular Property of Guadua Angustfolia (Iron Bamboo)

bamboo is said to be sustainable as it is a renewable and versatile product. The group of giant woody grasses is proven to be the fastest growing plants and extensively in most parts of the world. Guadua angustifolia is one of the most used materials in bamboo construction. Due to its small internode distance and the straightness of long bamboo culms, it allows it to be a versatile material when used in construction. The demand for assessing the mechanical properties of bamboo has also been increasing in the construction industry. Structural codes and standards are limited for some bamboo species since there are insufficient studies regarding the matter. In this study, the bending strength of G. angustifolia ‘Kunth’ (commonly known as Iron Bamboo) perpendicular to the fibers was established to characterize the bending property of the bamboo species. The latest PNS ISO 22157:2020 test protocol and guidelines from PNS ISO 22156:2021 were used to establish the bending strength from 41 characterized bamboo samples sourced from Cotabato City,
