A matter-element model evaluation method of reinforcement corrosion in reinforced concrete based on ideal point method

Abstract

The invention discloses a matter-element model evaluation method for reinforcing steel corrosion in reinforced concrete based on an ideal point method, comprising the following steps: constructing anevaluation system for reinforcing steel corrosion; performing Classical domain, section domain and matter-element to be evaluated of steel corrosion evaluation are determined. Determineing the magnitude range of each factor, find out the ideal critical point of each factor, determining the ideal control region of each factor; Obtaining the actual detection value of the influencing factor; performing Standardized treatment of influencing factors; Determining the weight coefficient; Ideal point method is used to evaluate the corrosion of reinforcing steel bar in reinforced concrete as a whole. When determining the weight coefficient, the invention reduces the human factor, and determines the weight according to the contribution rate of each influence factor to the steel corrosion.

Description

Technical field [0001] The invention belongs to the technical field of evaluation of the corrosion status of steel bars in reinforced concrete, and specifically relates to a matter-element model evaluation method for steel corrosion in reinforced concrete based on an ideal point method. Background technique [0002] With the continuous increase of passenger and freight volume in China, and many of the reinforced concrete infrastructures that carry transportation functions in China have entered the aging stage, there are multiple evaluation methods for whether they can meet the requirements of carrying capacity. As one of the main stress-bearing materials of the structure, the corrosion problem of steel bar is the key, and it has also attracted the close attention of many scholars. There are many factors affecting steel bar corrosion. The existing steel bar corrosion evaluation methods start from a single influencing factor. There is no perfect evaluation method that integrates va...

[0002] With the continuous increase of passenger traffic and freight volume in our country, and many reinforced concrete infrastructures carrying transportation functions in our country have entered the aging stage, there are various evaluation methods for whether they can meet the requirements of carrying capacity. As one of the main stress-bearing materials of structures, the corrosion problem of steel bars is the key, which has also attracted the close attention of many scholars. There are many factors affecting steel bar corrosion. The existing evaluation methods for steel bar corrosion are all based on a single influencing factor. There is no comprehensive evaluation method that combines various influencing factors to systematically evaluate the corrosion of steel bars.
