Great Wall steel casting: How to control the quality of steel casting Nodes

The steel casting Nodes is the hinge of force transferring in the design of steel structure and play an important role in the whole steel structure. It is the intermediate switch station for transferring the floor load and roof load to pillars. We can understand simply that ,if it appears quality problems of steel casting nodes in anti-seismic progress , the whole floor would collapse.Thus it is very important.
