Web4.1 Introduction to Trusses. A truss is a structure composed entirely of two-force members; that is, the members that have two equal and opposite forces applied at two points. Thus, since the members do not exert any torque on each other at the joints, they are considered to be pin connected. However, welded and riveted joints may be considered ...

WebCombined Stress Index (CSI) The summation of axial and bending stresses divided by their respective allowable stresses for a specific truss member. This ratio, or index, represents the structural efficiency of the member. The CSI shall not exceed 1.00. WebSteel and timber trusses are usually designed assuming pin-jointed members. In practice, timber trusses are assembled with bolts, nails or special connectors, and steel trusses are bolted, riveted or welded. Although these rigid joints impose secondary stresses, it is seldom necessary to consider them in the design procedure. http://swscorp.net/wp-content/uploads/2014/08/ttb-how-to-read-a-truss-design-drawing.pdf how important is sleep and why
