The scaled model shaking table test and a refined finite element model (FEM) computation were conducted in order to analyze the seismic behavior of Jinan Olympic Center, which is an out-of-code structure. A scaled model structure was established by general finite element analysis program SAP2000. The basic dynamic characteristics of the structure were analyzed through mode analysis. The stress ratio distribution of the stadium canopy roof’s steel members and the uniformity of the story stiffness distribution were investigated by response spectrum analysis and elastic time history analysis. The deformation capacity of the whole structure under rare earthquake was verified with the static elasticplastic analysis, and the horizontal seismic behavior was analyzed. Results showed that the FEM analysis results accorded well with the shaking table test results, and the calculation was reliable. The prototype has a rational arrangement of structural elements and good seismic performance, which meets the all requirements of the horizontal earthquake resistance demands from different levels on this site．
