摘　　要：对泉州郑成功雕塑进行结构选型研究,选定板片空间结构组合体系作为雕塑的主体结构方案。通过结构整体稳定分析,揭示了影响结构稳定承载的薄弱环节。根据分析结果可知,郑成功雕塑结构延性较好,虽然存在局部失稳现象,但不会发生整体极值点失稳。利用反应谱分析法和时程分析法进行结构抗震分析,并将结果进行比较。对马腿及马腿基底进行精细分析,可知相比空钢筒马腿,带约束锚栓的异形钢管混凝土马腿承载力更高;马腿基底变形不可忽略。The sheet spatial structure is selected as the main structure of Zheng Chenggong sculpture in Quanzhou after structural form selection. The weakness of the stability bearing capacity of the structure can be noticed through overall stability analysis. The results show that Zheng Chenggong sculpture has good ductility. Although there is local instability, the maximum point instability of the sculpture structure will not occur. A detailed study on the seismic analysis by both methods of response spectrum analysis and time history analysis was given, and the results of the two methods were compared. By analyzing the four horse legs and their basement, the bearing capacity of horse legs made by specially shaped concrete filled steel tubes with constraint anchor bolts is higher than that of horse legs made by specially shaped steel tube. The deformation of basement should not be ignored.
