Abstract:The concrete engineering part of Guirui Theater consists of two parts including semi-basement engineering and stage engineering. Semi-basement engineering is mainly composed of a north-south concrete bridge passing through the middle of butterfly roof and a small amount of semi-basement space under bridge deck. It adopts shear wall structural system. Stage engineering includes stage warehouse distribution room and other parts. The frame structure system and the shear wall structure system are selected respectively. The design and analysis of the  concrete projects were studied. Firstly, combined with the geological conditions and load conditions of the construction site, the foundation scheme and main design measures of the semi-basement engnieering were described in detail. Secondly, the design calculation method and design assurance measures of large-span concrete arch in semi-basement engnieering were mainly introduced. Finally, the key technical problems of stage structural design were briefly explained. The research and design results show that through reasonable structural selection and system design assurance measures, the design scheme of the semi-basement engnieering and stage engnieering can well meet the structural safety requirements and structural rationality requirements. The structure is safe and reliable, and the structural design is feasible.
