［摘要］對泉州鄭成功雕塑進(jìn)行結(jié)構(gòu)選型研究，選定板片空間結(jié)構(gòu)組合體系作為雕塑的主體結(jié)構(gòu)方案。通過結(jié)構(gòu)整體穩(wěn)定分析，揭示了影響結(jié)構(gòu)穩(wěn)定承載的薄弱環(huán)節(jié)。根據(jù)分析結(jié)果可知，鄭成功雕塑結(jié)構(gòu)延性較好，雖然存在局部失穩(wěn)現(xiàn)象，但不會(huì)發(fā)生整體極值點(diǎn)失穩(wěn)。利用反應(yīng)譜分析法和時(shí)程分析法進(jìn)行結(jié)構(gòu)抗震分析，并將結(jié)果進(jìn)行比較。對馬腿及馬腿基底進(jìn)行精細(xì)分析，可知相比空鋼筒馬腿，帶約束錨栓的異形鋼管混凝土馬腿承載力更高；馬腿基底變形不可忽略。

Abstract: 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.

Keywords: large complex structure; structural selection; stability analysis; seismic analysis; specially shaped concrete filled steel tube
