In the project, the green assembled composite wall structure was combined with the new wall boundary connection technology, and the green assembled composite wall structure system based on the new dry connection technology was put forward, in order to settle the following difficulties: joint wet connection existing in the assembled wall structure, low assembly efficiency, insufficient research and development of the efficient connection technology, rare research on the overall performance and seismic performance of the structure, imperfect design theory, immature integration technology, difficult to repair if damaged after earthquake, etc. New connection keys for dry connection technology of green assembled composite wall structure-"strong connection key" and "energy-consuming connection key" ware researched and developed; The working performance of the key component and the new connecting key in different stress phases was studied, and the characteristics of the stress deformation of the energy-consuming connecting device and the mechanism of energy dissipation and damping of the structure were discussed; The seismic design methods based on "strong connection" performance and "energy-consuming connection" performance were established respectively; The integrated integration technology of force-bearing, heat-insulation, weather-proofing and sound insulation of the dry joint splice interface of the structure was researched and developed. Through theoretical and technological innovation, the project aims to create a set of low-storey, multi-storey green assembled concrete structure system and its dry connection standard which adapts to the new urbanization construction in China, and to provide important theoretical and technical support for the construction of new urbanization in China.
