Why nodes are so important for steel structure design
Structural design principles: strong nodes weak components
In the design of the steel structure, the node plays the role of the power transmission hub, occupying the key position in the whole structure. The nodes act as intermediate transfer stations for transferring the load on the beam and the load of the roofing floor to the column. In the seismic process, if the node has quality problems, the whole floor will collapse, so strengthen the node design is important.
