［摘要］昆明世贸中心主体采用钢框架-核心筒结构,核心筒剪力墙平面形状为内切等边三角形,塔楼7,23,39层为结构加强层(避难层),分别采用了周边桁架、伸臂桁架的加强措施。通过合理的结构措施及对结构与构件抗震、抗风的受力分析，到达预期的性能目标要求，并对关键的节点进行研究，确保外框架与核心筒的协同受力。

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
