This is a standard pitched Roof Steel Truss Column Overhang Connection Detail. This detail illustrates 2 types of steel trusses. One with I-section profile top and bottom chords and the other with SHS section profile members.
Connection with a bolted top plate welded onto the supporting column with stiffener plates. Moment resisting connection bolted onto the bottom truss chord member. Column web is reinforced with stiffener plates.
All truss members are welded together with fillet welds.
Roof trusses, are commonly used in order to achieve large spans for creating large open space areas. Instead of large heavy primary girder beams, with very large profile sections, trusses also reduce the cost per steel unit weight of the construction.
Size of the truss and truss members depend on the loading conditions, design criteria as well as architectural restrictions. By enlarging the truss overall depth, greater loads can be achieved but in some cases this is not feasible due to architectural restrictions. Variations of truss depth and truss members can achieve the desired loading requirements, thus creating an infinite number of possible truss variations.
On top of that, truss openings can be very easily used, for passing all mechanical and electrical services within the truss depth, thus eliminating further downsizing of the ceiling clear height. Once the mechanical ducting services are obtained, one can design the truss with given minimum and maximum depth and sizing in order to achieve the best feasible result.
This is a great truss detailed drawing template that can be used with almost every design. Sizing can be altered with minimum CAD commands to match every design requirements.
