陕西大厦结构设计

Structural Design of Shaanxi Mansion

陕西大厦为超高层建筑,钢筋混凝土框架-核心筒结构,北侧、西侧层12以下采用斜框架,首层楼板开有较大洞口,顶部几层竖向荷载较大,首层地面以下2m即为地下水。在结构设计中,对框架的总剪力按照高规的要求进行了调整,斜框架柱的内力按中震作用进行了复核设计,按零刚度板复核斜柱内力及其水平分力,斜柱产生的水平分力由与其相连的框架梁传至核心筒,考虑稳定水位对建筑物正常使用极限状态下的有利影响。通过结构的整体分析和各项补充分析,结构的变形和承载能力都满足要求,结构设计合理。

Shaanxi Mansion is a super high-rise building with frame-core wall structure.The structural system below the 12th story in the north and east is diagonal frame.It has a rather large opening in the first floor,and great vertical load on the top floors.Underground water can be found below the first ground 2m.During the design,the main jobs are setting the total shear of the frame according the technical specification for concrete structures of tall building,checking the horizontal force of the inclined columns when experiencing the intermediate earthquake and checking the internal force and the horizontal force considering non-rigidity plate.The horizontal force of the inclined columns is transferred to the core wall along the frame beams connected with them.The analysis is also considering the favorable effect in the case of stable water height of the regular service limit state.The results show that the deformed and the bearing capacity can meet the request and the design is appropriate can be concluded though the global analysis and kinds of supplement analysis.
