［摘要］山东大乳山西黄岛Y形产权式度假酒店位于烈度低、风压大的地区，采用剪力墙结构体系。结构设计中存在以下问题：平面为不规则的Y形，结构抗侧与抗扭刚度不足；由于平面不规则且中部筒体楼板开设洞口，导致楼板受力较为复杂；结构设计中风荷载起控制作用。针对以上的问题，提出了三种结构方案，并通过对比分析优选了结构方案；通过采用SATWE，MIDAS/Gen和YJK三种软件对结构进行的整体分析。结果表明，所优选的结构方案具备较好的抗扭与抗侧刚度；通过采用YJK软件对楼板进行的应力分析发现，各肢结合部位楼板存在应力集中，提出了对此部位的加强措施；根据结构抗震性能化设计提出了结构的抗风性能化设计，对该结构进行Pushover分析，讨论了结构不同阶段的受力性能，并采取了相应的加强措施。

Abstract:The Y-shaped property hotel on Xihuang Island in Shandong Darushan is located in area with low seismic intensity and large wind pressure. The hotel adopts shear wall structural system. In the structural design, the following problems exist: the plane is irregular Y-shaped with insufficient torsion and lateral-resisting rigidity of the structure; and the stress of the floor is complex due to irregular plane and floor openings in central part of the tube; wind load is dominant load in structural design. In view of the above problems, three structural schemes were proposed and the structural scheme was optimized through comparative analyses. Three softwares of SATWE, MIDAS/Gen and YJK were used to carry out overall analyses of the structure. Analyses show that the preferred structural scheme has good torsion stiffness and lateral stiffness; the stress analysis carried out on the floor by YJK software shows that stress concentration exists in floors that are in connection parts between wall limbs and strengthening measures were proposed to these parts; performance-based wind-resistant structural design was proposed according to performance-based seismic structural design. Pushover analysis was carried out on the structure to discuss mechanical behaviors of the structure in different stages, and corresponding strengthening measures were taken.
