The design examples provide coverage of all applicable limit states whether or not a particular limit state controls the design of the member or connection. This paper presents two simple methods for the design of steel gusset plates. Results for design purposes An example from his book is shown in Figure 9 which shows the calculated stress distribution in a gusset plate with a discontinuous bottom chord member at the panel point of a truss.

Example 12 Design the same plate of Example 11 using the stiff approach and assuming 1 ¼ diameter bolts. In general the height of the truss members can be taken as the 115 or 120 of the panel length Tachibana 2000Typical cross section for truss members are I-section and box.
