Based On The Salt Fog Corrosion Concrete Flexural Members Of The Nonlinear Analysis

Reinforced concrete structure is used in building up, one of the most common forms of structure. Because it is widely, reinforced concrete structure in different fields and the environment is more and more of the durability of the engineering professionals at home and abroad. Under the environment of corrosion of reinforced concrete structure durability problem appear particularly outstanding. And the most common is the corrosion of chlorine ion in coastal and winter use deicing salt area concrete structure to chlorine ion in structure, the erosion of early damage of structure, durability, safety and reliability, bring great harm. This issue has caused the people's extensive concern, and become a research hotspot. Most studies both at home and abroad are based on the concrete structural components in seawater erosion completely, but in fact suffer such corrosion's rather unusual. Coastal area is more buildings suffered chlorine ion in the air.This topic is hope through salt fog corrosion test the accelerated corrosion to study in concrete structures containing chlorine ion in the air, through experiment and finite element analysis of the two methods of the reinforced concrete beam under the environment of chlorine ion in the mechanical performance analysis and contrast, for different concrete cover depth and strength of concrete beam crack load, the ultimate flexural loads, in contrast, detailed research, illustrates the finite element analysis method is an effective method. And through the finite element model of the corrosion under the environment of the durability of the concrete structure analysis and prediction. For the finite element analysis method in the analysis of corrosion subjected to bending application provides basis for actual project, but also in the prevention of corrosion and provides the theoretical basis.
