［摘要］对国家金融信息大厦核心筒墙肢由双向设防地震作用引起的墙肢拉应力进行了分析，分别探讨了伸臂设置、环带桁架刚度、底部斜撑等影响因素的作用。分析结果表明，伸臂低位设置可显著降低墙肢拉应力；提高环带桁架刚度可有效降低墙肢拉应力，但其对楼层侧向刚度比的影响显著，不利于结构竖向规则性控制；底部斜撑可在不影响楼层侧向刚度比的情况下有效降低墙肢拉应力，为优选的方案。

Abstract: The wall tension stress of core-wall in National Financial Information Center caused by bidirectional moderate earthquake was analyzed, the influential factors including the setup of outriggers, stiffness of belt members and bottom braces were discussed. The results show that lower-setting outriggers can obviously reduce the wall tension stress; enhancing the stiffness of belt members can effectively reduce the tension stress, but it can also amplify the stiffness ratio of the story，which is adverse to control the vertical regularity of the structure; the bottom braces can effectively reduce the tension stress but have no obvious influence on the lateral stiffness of the structure, which make it an optimal solution.

Keywords: super high-rise building; frame-corewall structure; wall tension stress; outrigger; belt member; bottom brace
