This study aimed to evaluate some basic mechanical properties of selected bamboo species that are applicable to structural applications. Seven bamboo species planted inside the Central Mindanao University Campus were tested, namely: Dendrocalamus merrillanus, Elmer; Gigantochcloa atter, Hassk; Bambusa vulgaris Var. Schrad; Dendrocalamaus asper, Schultes. F; Dendrocalamus latiflorus, Rehm.; Bambusa vulgaris Schrad.; and, Bambusa blumeana, Schultes were subjected to four-point bending test,

Result showed that Dendrocalamaus asper, Schultes. has the stronger compressive strength at an average of 104.02 MPa, Dendrocalamus latiflorus, Rehm. has the stronger shearing strength at an average value of 12.65 MPa, while Dendrocalamus merrilanus, Elmer has the stronger flexural strength with and average value of 188.39 MPa. All six bamboo species tested is 2-6 times stronger than 80% stress graded Vitex parviflora Juss. (Molave) in compressive strength, 1.7-4.4 times stronger in shearing strength and 1.4-7.85 times stronger in flexural strength.
