Abstract
Bamboo is the world's fastest-growing grass species.Although bamboo is a resilient and sustainable engineering material, its use in the building sector has been limited.The limitation in the usage is most likely due to its nature, which might vary depending on the species and origin, creating a challenge in establishing standard design guidelines.As a result, further research into the fundamentals of bamboo as a structural material is required.The Finite Element (FE) method is used in this study to evaluate the elastic critical buckling loads and mode shape of two local bamboos under different lengths and boundary conditions.The proposed local bamboo was modelled in ABAQUS software version 6.14.The findings reveal that Dendrocalamus asper has greater buckling strength due to its physical dimensions than Bambusa vulgaris under the same length and boundary condition.In terms of length and boundary conditions, six-meter length bamboo with fixed-pinned ended conditions can resist higher elastic critical buckling load than six-meter bamboo with fixed-free ended conditions.Consequently, the difference in elastic critical buckling load between the finite element approach and Euler's theory calculation is less than 2%, indicating that the two methods are in good agreement.
