Based on the pitting corrosion characteristics of corroded deformed steel bars embedded in concrete structures in chloride environment, the Finite Element fine Model is established by the ANSYS FE software, and nonlinear analysis was conducted for the influence of corrosion pit on the resistance properties of steel bars. Results show that the effect of pit location is apparent on the mechanical properties...
In this report, a novel signal processing method for microwave radar is considered, in order to realize precise diameter measurement of the reinforcing bars and the steel pipes in the concrete structures. Particularly, a geometric analysis which is considering the bi-static antenna configuration for the microwave propagation paths is introduced, and a diameter of the buried circular target object...
In this report, an advanced signal processing method for microwave radar is considered to reconstruct a precise 3D image for inner construction in concrete structuresC which consists of reinforcing bars and pipes. An antenna positioning error and an inappropriate signal processing method have caused a degradation of reconstructed images. First, a handy antenna scanning system has been modified, which...
Considered in assessing durability of concrete structures on the basis of factors was finished. Concrete structures for specific components, to assess the durability nodes do not contain many intellectual, select the most impact on the durability of concrete structures to assess factors as indicators, used uncertainty comprehensive evaluation model, the establishment of concrete structures to assess...
