［摘要］宁波保康光明医院主体部分采用框架剪力墙结构体系。设备层上下楼层在地震作用下形成两个过于接近的薄弱层。分析了结构及构件的主要受力特征，通过调整下部剪力墙的布置、调整构件截面尺寸以及采取一定的抗震构造措施，防止薄弱层在大震作用下发生严重破坏。计算结果表明，结构的变形和承载力均满足要求。以该结构设计为工程背景，介绍了具有双薄弱层框剪结构的抗震概念设计方法，所采用的主要技术措施可为类似工程设计提供参考。

Abstract:The fram-shear wall structure is adopted in Ningbo Baokang Sunshine Hospital. Two weakness floors near the equipment floor are formed under the earthquake. The characteristics of the structure are analyzed. In order to prevent the weakness floor destroy seriously under rare earthquake, some measures are used, such as adjusting the location of shear walls and the section of members. The structure analysis results show that the deformation and bearing capacity satisfy the demands of the code. Based on the engineering design, the anti-seismic conceptual design method of frame shear-wall structure with double-weakness floor is given. The main technical measures can be referred in similar engineering.
