Methods of determining transverse mechanical properties of full-culm bamboo

► Edge bearing test to obtain transverse material properties of bamboo is proposed. ► Effect of through-culm-wall fiber gradation on edge bearing strength is explored. ► Strain profile shift of the neutral axis is less pronounced in thin wall sections. ► Observations will lead to more reliable through-wall properties being established. ► Properties may be used to refine modeling of full-culm bamboo materials.
