Abstract: Based on the ideas of modular design, the structural integration design strategy was put forward, morphological adaptability design strategy and functional compound design strategy for the enclosure system of tall and large space in north China were proposed. Taking the design process of the cable-tensioned box arched enclosure system as an example,how to realize the integration of supporting structure and enclosure interface by the synergistic action of cable and arch was discussed. Shape control and module partition replacement were used to meet the different functional requirements and construction conditions. Multi-layer cavity and integration structure were used to realize the functional compound of unit module. The above design strategies were applied to develop a modular enclosure system with the advantages of reasonable structure, simple structure, good adaptability, convenient installation and disassembly, repeated use, the sytem could adapt well to the climate and construction conditions of cold area, realize the green sustainable goals such as saving energy, manpower, construction period and so on.
