摘要
由耐久性不足引起的混凝土结构劣化问题给社会带来了越来越严重的经济负担,日益得到各国工程界和经济界的高度重视,保证结构的安全和经济合理是建筑工程决策的主要问题。讨论了混凝土结构全寿命安全和经济分析的方法,提出了基于可靠性的费用分析方法和考虑耐久性的劣化混凝土结构可靠度评估框架,并讨论了提高建设项目长远经济目标的措施和建议。
The problems of the deterioration of RC structures which due to durability deficiency bring more and more economic burden to the society.They are attached increasingly importance by engineering and economic realms.It is main object of the decision-making of construction projects to ensure structure safety and economic reasonable.This paper discusses the methods of life-cycle safety and economic analysis of RC structures,and proposes the cost analysis methods based on probability and the framework of reliability assessment of deteriorating RC structures considering of the structural durability.The measurements and suggestions of enhancement of long-term economic objectives of construction projects are given out.
