Wood members under axial and bending loads book
This chapter considers the four basic design cases for axially loaded members and the corresponding loading conditions that are as follow: Tension: Truss members, diaphragm chords, drag struts, and shear wall chords, Tension plus bending: Truss bottom chord members, Compression: Columns, wall studs, truss members, diaphragm chords, drag struts, and shear wall chords and Compression plus bending: Exterior columns, wall studs, and truss top chord members. Some examples of members subjected to combined axial tension and bending loads include truss bottom chords and door headers subjected to bending from gravity loads and tension from acting as a chord member in a roof or floor diaphragm. Bending plus tension occurs at the bottom of the member at the point of maximum moment, where the moment and tension force are at their maximum values, Creating maximum tension stress in the tension or bottom fiber of the member.
