Combined Loading for Wood Members
Thus far, we have discussed structural members subject to bending stress against one axis or pure axial stress (tension or compression). Oftentimes, however, structural members must be designed to resist a combined loading condition. For example, the load on a column may be off-center, causing both an axial stress and a bending moment. This chapter includes discussions of the following types of combined loading: single axis bending and axial tension, single axis bending and axial compression, eccentric loads on columns, and biaxial bending. Figure 7.1 illustrates these loading conditions.
