摘要: 为充分掌握再生利用项目建筑结构安全性状况,保证使用过程安全可靠,结合再生利用项目特点,构建再生利用项目建筑结构安全性评定指标体系;采用物元可拓法建立再生利用项目建筑结构安全性评定模型,计算关联度函数,采用组合赋权法确定指标权重,得出再生利用项目建筑结构安全性评定等级,并选取实际工程项目加以验证。研究结果表明:该模型能够确定结构安全性评定等级,且评定结果与现场情况基本吻合,能够反映再生利用项目的建筑结构安全性状况。

Abstract: In order to fully grasp safety status of building structure for regeneration projects and ensure its safe and reliable use, a safety assessment index system was constructed according to characteristics of regeneration projects. Then, a safety assessment model was established by adopting matter-element extension method, correlation function was calculated, and index weight was determined by combination weighting method. Finally, safety level of building structure was obtained, and a real engineering project was employed to verify this model. The results show that this model can determine structure safety level which is basically consistent with actual situation, thus verifying its effectiveness in reflecting safety status of building structure for regeneration projects.

Key words: regeneration, building structure, safety assessment, matter-element extension, combination weighting
