Abstract:The design and construction process of a four-story building with precast concrete frame was introduced systematically, according to characteristics and development status of precast concrete structure. The research mainly focused on analyzing design and construction features of auxiliary  steel connection and monolithic precast connection applied on this case, in terms of structure design, checking calculation of construction, component production, joint construction and construction measures. In addition, the monolithic precast concrete frame with auxiliary  steel connection was studied by comparing with the cast-in-place frame from the economic point of view. It is concluded that the monolithic precast concrete structure with auxiliary steel connection is a very suitable structure type for development direction of building industrialization, based on high-quality structural members, construction efficiency, technical and economic rationality.

Keywords:precast concrete frame; monolithic precast; auxiliary steel connection; sleeve
