A platform for research: civil engineering, architecture and urbanism
The study of load tracing begins with gravity loads and a grid of horizontal elements. The primary elements are called girders, the secondary elements are called beams. Secondary implies that these members have a lower hierarchical standing, they rely on (connect to) the primary members which we call girders. The beams may be long, or they may be short. Architectural concerns may call for having longer beams connecting to girders, which may have shorter spans but subsequently larger bending moments. Good practice would call for having both of these elements at roughly the same depth so that floor thickness remains somewhat constant. In timber and steel construction, it is common to assume that the secondary beams are simply supported at their ends, i.e. they do not transfer bending moment to the girders. This is symbolized by a gap in the drawing of the connection. In this chapter, the girders are also always assumed to be simply supported to the columns, but along their length they carry moment across each connection. Thus, in Fig. 3.1, the girder passing from span AB to span BC does transfer moment at that intersection, whereas the beam along B connects simply to the girder at B, no moment is transferred.
