Of the two material areas can be calculated. With the neutral axis (NA) located, the moment of inertia about the NA for each Now that the distance h is known, the location of all material area centroids The steel section consists of two parts, 1 and 2, giving, The NA can be determined from the equation The distance to the outside edge of both materials require knowing where the Solving for bending stresses in composite beams. The location of the neutral axis (NA) is one of the most critical steps when This is a common beam loading and the maximum momentĬutting the beam at the center and summing the moments gives This moment is not a function of the cross section and can be determined by the moment diagram. To determine the maximum bending stress, the maximum bending moment is needed. Next, the neutral axis needs to be determined.įrom there, the actual moment of inertia for each material can be found.

This is needed for theĬomposite beam bending stress equations.

The first issue is to find the actual maximum moment. Treated as a single material with two areas. The wood will be treated as one material and the two plates will be The beam is a composite beam of only two materials even though there are three Of 2 kN/m over a simple support span of 5 m. The plates are rigidly attached to the top and bottom surface of the wood memberĪs shown in the diagram at the left. The ceiling beam is composed of three parts, two steel plates and a wood member.
