［摘要］北京市某高層住宅小區(qū)設計使用年限100年，主體結構采用剪力墻結構體系。針對該住宅設計使用年限100年的關鍵問題，從“百年住宅”結構設計技術體系出發(fā)，從結構布置、結構安全、主體耐久等方面，對地震作用、荷載取值、結構重要性系數(shù)、混凝土耐久性、鋼筋保護層厚度等方面進行了設計探討。得出如下結論：地震作用可通過確定設計使用年限100年相同超越概率的地震動參數(shù)來確定；樓、屋面活荷載及基本風壓、基本雪壓取值均應針對100年設計使用年限進行相應調(diào)整；同時應加強結構使用階段的維護與檢修，以保證結構的100年耐久性。
［關鍵詞］設計使用年限； 地震作用； 耐久性； 維護與檢修

Abstract:A high-rise residential district located in Beijing has design working life of 100 years and the main structure adopts shear wall structural system. Aiming at the key problem of design working life of 100 years, the structural design technological system of the 100-year-old high-rise residential building was analyzed from perspectives of the structural layout, safety and the durability, as well as earthquake action, load value, importance factor of structure, concrete durability and concrete cover thickness. Conclusions are that the earthquake action can be determined by determining the ground motion parameters with the same surmount probability of design working life of 100 years; live loads of floor and roof, and the basic wind pressure and the basic snow pressure values should be adjusted correspondingly to design working life of 100 years. Maintenance and inspection in structural use phase should be strengthened to ensure the 100 years of durability of the structure.
Keywords:design working life; earthquake action; durability; maintenance and inspection
