［摘要］昆明世貿(mào)中心主體采用鋼框架-核心筒結(jié)構(gòu),核心筒剪力墻平面形狀為內(nèi)切等邊三角形,塔樓7,23,39層為結(jié)構(gòu)加強層(避難層),分別采用了周邊桁架、伸臂桁架的加強措施。通過合理的結(jié)構(gòu)措施及對結(jié)構(gòu)與構(gòu)件抗震、抗風的受力分析，到達預期的性能目標要求，并對關(guān)鍵的節(jié)點進行研究，確保外框架與核心筒的協(xié)同受力。

Abstract: The Kunming World Trade Center main body uses the steel frame-core tube structure, the core tube shearing force wall planformed for the interior contact equilateral is three angular, and the 7, 23, 39 floor of the tower are strengthened, the structure enhancement level (seeks asylum level) has used the peripheral truss, the cantilever truss enhancement measure separately. Through the reasonable structure measure, the structure and the component were analyzed about earthquake resistance and wind resistant stress, the structure was arrived performance goal request. The key node structure procedure outside was researched to ensure collaborative force outside the framework and core tube.
Keywords: interior contact triangle tube body; steel-pipe column; week side ring truss; cantilever truss; high intensity area; core tube tensile stress
