本文简要介绍了钢筋混凝土结构中锈蚀产生的影响。考虑到这些影响，提出了一种评估它们对损伤构件结构性能影响的方法。为此，研究了以下几个方面：a)腐蚀侵彻的评估；b)混凝土保护层的腐蚀侵彻与开裂之间的关系的研究；c)由于腐蚀过程导致的粘结强度降低的评估；以及d)钢筋混凝土构件受腐蚀破坏的承载能力评估模型的应用。文中对这些观点作了简要的描述，并给出了上述步骤的某些方面的实验数据。腐蚀侵彻的评价可以利用尤里卡项目EU-401下开发的设备进行。其他三个步骤正在Brite/Euram项目BE-4062中开发。封面摘要见IRRD 867793。
This paper presents a brief description of the effects produced by corrosion in a reinforced concrete structure. Taking into account these effects, an approach is developed for evaluating their effects upon structural performance of a damaged element. In order to do this the following aspects are studied: a) an evaluation of the corrosion attack penetration; b) a study of the relationship between attack penetration and cracking of concrete cover; c) an evaluation of reduction in bond strength due to corrosion processes; and d) application of models for assessing the load carrying capacity of reinforced concrete elements damaged by corrosion. These points are briefly described in the paper, and experimental data are presented on some aspects of the above mentioned steps. The evaluation of the corrosion attack penetration can be carried out by means of equipment developed under Eureka project EU-401. The other three steps are being developed in Brite/Euram project BE-4062. For the covering abstract see IRRD 867793.
