【摘要】 提出了广义耐久性概念及劣化度函数的理念,对钢筋砼结构耐久性寿命评判与预测方法进行了研究,并围绕所确立了的劣化度指标及评判准则建立了相应的耐久性评价体系,2套评价体系皆以试验为基础分别建立侵蚀性物质侵蚀深度模型和钢筋锈胀的力学模型,最后基于2个模型进行了混凝土结构的失效概率与可靠性分析.更多还原

【Abstract】 This paper presents a full set of research methods of endurance life’s judgment and prediction about steel concrete structures based on several years’ study works,which includes putting forward concept of generalized durability and deterioration grade function,and establishing corresponding endurance evaluation systems around the built deterioration grade indexes and judgment criterion.The built two sets of evaluation systems all need establishing erosion matter’s erosion depth model and steel corrosion and expansion of mechanical model separately based on experiment.It is feasible to analyze the structure failure probability and reliability based on the two models.更多还原
