混凝土结构耐久性及其稳健回归分析

混凝土结构耐久性是结构设计中需要考虑的一个重要指标,在工程实践中,随着时间的流逝,混凝土结构耐久性不足问题逐步暴露,逐渐引起了工程界的广泛关注。随着使用时间的延长,混凝土界面的变小或混凝土质量的退化以及钢筋的锈蚀,是导致结构构件的强度退化的主要原因。在试验的基础上对现有的钢筋混凝土结构进行耐久性分析,得出这方面相关的重要数据,为以后的设计和施工奠定数据基础,并为科学的解决混凝土耐久性问题提供重要的依据。

Robust regression analysis of the durability of concrete structure

The durability of concrete structure is an important indicator of the structural design.In engineering practice,with the passage of time,the problem of insufficient durability of concrete structures exposes gradually,and this problem has aroused extensive concern in the engineering sector.With prolonged time of use,smaller concrete interface,the quality of concrete degradation and corrosion of reinforcing rods are the main reasons for strength degradation of structural elements.On the basis of important data obtained by the experiments durability analysis of existing reinforced concrete structure will lay a data base for future design and construction,and provide an important basis for a scientific solution to the durability of concrete.
