WebFor a rectangular wood beam, shear is not carried equally across the section, and has a maximum stress higher than an average stress. So when we calculate shear stress, we divide the shear force by the area of the section, but must also multiply by 1.5. Then we can check the shear stress with the allowable shear stress, from the material tables. WebWood beams are generally designed for bending stress and then checked for shear and deflection. Using allowable stress design, the required section modulus is found by dividing the maximum bending moment by the adjusted allowable bending stress, Fb ' , as shown in Equation 1.24.

WebWorking Properties: Ipe lumber can be somewhat difficult to work with, especially with hand tools. Can have quite a blunting effect on cutting edges. Recommended that you use a reduced cutting angle, keep edges sharp, and always predrill for nails or screws. Have numerous extra drill bits handy. http://faculty-legacy.arch.tamu.edu/anichols/index_files/courses/ends231/symbols.pdf
