Many problems of long spanning in structural engineering can be resolved through the use of steel trusses. These days, long span structures are very popular– from sport arena roofs to auditorium galleries, airport terminals, railway stations etc….
A truss is a triangulated assembly of interconnected elements, pinned at the nodes and typically having all external forces and reactions applied at the nodes (Figure 1). Trusses are extremely strong and a very cost-effective solution when compared to other structural options
Column base plates are provided beneath steel columns in order to transmit the applied design forces safely to the foundations. Steel columns are heavily loaded and their cross-sections are typically small…….
The most common form of steel connections in steel-framed structures is simple connections. These are connections that are incapable of transmitting significant bending moment between the frame elements.
