【摘要】 陕西延长石油科研中心超高层塔楼高度195.45m,采用"钢管混凝土柱+H型钢梁+钢筋混凝土核心筒"结构,设有1层伸臂桁架。为了使外框架承担的地震剪力标准值达到规范及超限审查的要求,对结构方案做了优化对比,取消楼梯间混凝土角筒代之以钢管柱+型钢梁+中心支撑。计算表明效果明显。最后介绍了中庭幕墙结构及入口门厅雨篷结构等设计难点及解决方法。更多还原

【Abstract】 The Shaanxi Yanchang Petroleum Headquarters Tower is 195. 45 m in height,and the structural form of the building is concrete filled steel tubular column and H-section steel beams combining reinforced concrete core tube. An outrigger system has been settled in a layer of the building. In order to meet the requirement of the outside frame to bear the seismic shear force,the structural scheme has been modified,and the concrete tube in the staircase has been replaced by the steel column with concentrically steel frames. The result of the calculation shows that the effect of this structure modification is significant.Furthermore,the difficult point and its solution of the structural design such as the structure of the curtain wall of the mid hall and the awning of the entrance is showed.更多还原
