1. First of all, according to the building function requirements, the use of appropriate reasonable structure system. So that advanced technology, novel structure, to achieve the perfect unity of architecture and structure.
2. Steel structure (except container) and more to the main bar, so the size of the rod as much as possible modular, standardized, easy to mechanized manufacturing, transportation, installation, improve productivity.
3. The use of high economic indicators of high efficiency steel.
4. The steel structure of the node is essential, to use the appropriate connection, so that the node design and structural simplification model is consistent. In the past, most of the structural damage occurred in the node, so the nodes should be carefully designed and carefully constructed, using advanced and reliable connection method.
