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...

Select a suitable wide flange section to support the beam loads shown in the figure below. Use ASTM A992 steel and allowable stresses of 0.66 Sy for bending and 0.40 Sy for shear. Be sure to generate a list of candidate beams from which, you will choose the lightest. Determine the factor of safety in bending for the beam you select. Find the deflection at the end of the overhang using the beam you selected. What is the total weight...

An I-beam has a flange width b = 200 mm , height h = 200 mm ,
web thickness tw = 8 mm , and flange thickness
tf = 12 mm . Use the following steps to calculate the
shear stress at a point 65 mm above the neutral axis.
Part A - Moment of inertia
The shear formula includes the moment of inertia of the whole
cross section, I, about the neutral axis. Calculate the moment of
inertia.
