[提要] 已有結構的維修、加固是目前土木工程界研究的重要內容之一,結構加固后的可靠度有多大,目前尚未有這方面的資料。對鋼筋混凝土軸心受壓構件加固后可靠度的研究表明,當鋼筋混凝土軸心受壓構件按《混凝士結構加固技術規(guī)范》(CES25:90)進行加固設計時,構件的可靠度滿足統(tǒng)一標準的要求。
[關鍵詞] 混凝土結構 維修加固 可靠度
The repair and rehabilitation of exist structures is an important aspect in civil engieering. How is the reliability of the structure after rehabilitation? The reliability of reinforced concrete axis memlers after rehabilitation is researched. It is shown that the:eliability of reinforced concrete axis members after rehablitation meets the requirement of United Standard when it is designed as Concrete Structures Rehabilitation Technical Code (CECS 25:90).
Keywords: concrete structures; repair; rehabilitation; reliability
