| Abstract: | The roof of a combined workshop is an orthogonal spatial square pyramid grid with bolt-sphere joints and welded-sphere joints.Authors introduce stress of two kinds of joints produced during construction and the control measures.The steel grid is divided into five unit bodies during construction.Per unit body adopts the installation technologies of assembling on ground and lifting with four tower cranes,which assure construction frequently. |
