[0002] A truss made of steel bars as top chord, bottom chord and web members and connected by resistance spot welding is called a steel bar truss; a combined load-bearing slab in which the steel bar truss and the bottom plate are connected as a whole by resistance spot welding is called a steel bar truss floor slab.
