ABSTRACT
The externally applied loads acting on the pin-jointed trusses are usually due to snow and self-weight, and also due to wind, as shown in Figure 6.1. In Figure 6.1, the snow and self-weight loads act vertically downwards and the wind loads are usually assumed to act horizontally. Thus, for structures such as that shown in Figure 6.1, where the externally applied loads are assumed to act at the pin-joints, the internal members of the framework resist the externally applied loads in tension or compression.
