［摘要］海埂酒店大堂平面超长、大开洞，平面扭转不规则，竖向错层较多，地下室及层1使用功能复杂，分析计算及构造做法有一定难度。结构计算时采用SATWE，PMSAP，MIDAS三种软件对计入双向水平地震作用下的扭转影响进行分析计算和比较，并验算了罕遇地震下的薄弱层弹塑性变形，所有计算指标均能满足现行规范的要求。采用了钢筋混凝土、钢骨混凝土、钢三种不同材料的结构构件与组合，节点构造复杂，施工有一定难度。通过对结构选型、参数取值、分析计算结果、细部大样的整理和分析，论述了结构设计中遇到的问题及采用的解决方法。

Abstract:The lobby of Haigeng Hotel has an over-long plane, large openings, irregular plane torsion and multiple vertical staggered floors.  The basement and the first floor are of complex functions, which result in difficulties in analysis and structural methods. By using SATWE, PMSAP and MIDAS in structural calculation, analytical calculation and comparison were made according to the torsion effect considering bi-directional horizontal earthquake action, and the elastic-plastic distortion of weak layers under rare earthquake was also checked. All calculation indexes meet the requirements of current specifications. Structural members and combinations of three materials including reinforced concrete, skeleton reinforced concrete and steel are used in this structure, and the joints are complex, which bring certain difficulties in construction. By analyzing structural form selection, parameter selection, analysis and calculation results,  details, the problems in the structural design of the lobby of Haigeng Hotel were discussed.
Keywords:Haigeng Hotel; lobby; structural design
