Bengbu Olympic Sports Center,as the home hall of the fourteenth Anhui Provincial Game,adopts a structure system of "large cantilevered prestressed steel beam-multi point circular tube support with three directions",which is composed of large and small steel awning structure,laying Al-Mn-Mg metal plate outside,showing the effect of the dragon scale building.In order to ensure the quality and structural safety of this steel structure in the Bengbu stadium during the whole construction process,the construction method and process are analyzed in depth in this paper.The whole model of large cantilevered prestressed steel awning structure in Bengbu stadium is built by using MIDAS software.The mechanical performance analysis is carried out on the whole process of steel component assembling,prestressing tension and unloading.The stress and vertical displacement of key components and joints are monitored,and the field measured values are compared with the results of finite element analysis.The changing rule of stress and displacement during the construction process is summarized.The analysis results show that the field monitored data and numerical simulation results match well and this verifies the new construction method and the reliability of construction sequence.The results of this paper can provide a reference for the application of similar projects.
