Learning Goal: To calculate the shear stress at the web/flange joint in a beam and use that stress to calculate the required nail spacing to make a built- up beam. A built up beam can be constructed by fastening flat plates together. When an l-beam is subjected to a shear load, internal shear stress is developed at every cross section, with longitudinal shear stress balancing transverse shear stress. If the beam is built up using plates, the fasteners used must...

Review An engineered wood beam (Figure 1) will replace a portion of a structural wall as part of a house renovation. The beam can be modeled as a simply supported beam with a span L = 18 ft and an uniform distributed load w = 810 lb/ft . The beam is to be constructed as an I-beam with nails securing the flanges to the web. The flanges are 6 in wide and 1 in thick. The web has depth 18...

Figure 1 shows A fully symmetrical I beam of area A1 = 5472 mm?, and second moment of areal = 59.9 x 10 mm' that is strengthened by attaching a plate of 10 mm thickness and 100 mm breadth at the top as shown in Figure 2. Pairs of 12 mm diameter steel bolts are used at regular 200 mm spacing along the beam to connect the plate to the I beam in an arrangement as shown in Figure 3....
