Shear Strength of Red Meranti (Shorea Spp.) Timber at an Angle to the Grain
The shear strength is one of the parameters that is used for the design of beam members in wood buildings. Shear strength is also used as a parameter for bridge girder design. Red meranti (Shorea spp.) is a species that is easily found in Indonesia and is commonly used as a construction material for buildings, docks, or bridges. The objective of this study is to obtain an empirical equation for the shear strength with different grain angles from 0° to 10°. The research of the influence of the grain angle must be carried out under real conditions, since the direction of the wood grain is not perfectly 0° and the inclination of the grain can influence the shear strength of the wood. The method of making the specimens and the experimental methods refer to ASTM D143-22, and the total number of test specimens was 33 specimens. The tests were performed using a universal testing machine, with the test speed (crosshead) 0.6 mm/minute. The test results show that the shear strength of wood with a directional fiber angle ranging from 0° to 10° in a range from 2.77 MPa (10° grain angle) to 7.57 MPa (0° grain angle). The results of the analysis by the polynomial regression method give an empirical equation, namely Fv = 7.03 − 0.97θ + 0.066θ2 with R-Sq = 74.7%. Fiber angle has an effect on shear strength. Empirical equations offer advantages to building designers in calculating the design capacity of wood beams, especially due to shear forces.
