Abstract
Due to the lack of analysis of the objective stress demand of concrete members in long-span building structures,the concrete beam structure has a large displacement under load.Therefore,this paper puts forward the application research of concrete in the construction of long-span building structures.Analyze the stress requirements of concrete members,and take meeting the load requirements of buildings as the core goal;Then the experimental loading device is designed,and the concrete with strength grade above C30 is selected as the construction material,and the reinforced concrete beam and the steel reinforced concrete column are optimally connected,and the length and axial compression ratio of the concrete beam are differentiated.Experiments show that the displacement of the concrete structure in the x,y and z directions of this project is stable within 0.3,0.4 and 1.0 mm respectively,which are all at a low level,thus proving that the technology designed in this paper has good practical application effect.关键词
