Spatial Variability of Pitting Corrosion and Its Effect on the Strength and Reliability of Prestressed Concrete Bridge Beams
نویسندگان
چکیده
Corrosion of reinforcing and prestressing steel due to chloride attack is one of the major causes of deterioration of concrete structures. This is of most concern because of the associated reduction in steel cross-sectional area, spalling and loss of bond. In the case of prestressed concrete structures, the corrosion of prestressing strands can lead to a sudden failure due to higher stress levels in the steel.

Reliability Analysis of Corroded Reinforced Concrete Beams Using Enhanced HL-RF Method
Steel corrosion of bars in concrete structures is a complex process which leads to the reduction of the cross-section bars and decreasing the resistance of the concrete and steel materials. In this study, reliability analysis of a reinforced concrete beam with corrosion defects under the distributed load was investigated using the enhanced Hasofer-Lind and Rackwitz-Fiessler (EHL-RF) method base...
متن کاملFlexural Performance of High-strength Prestressed Concrete-encased Concrete-filled Steel Tube Sections
The sections composed of concrete and steel, which include concrete-encased concrete-filled tubes, generally have defects due to the low tensile strength of concrete. Therefore, an appropriate method was used for the combination of concrete-filled tubes (CFT) and prestressing strands which is encased in concrete. The conventional design guidelines are commonly developed for materials with norma...
متن کاملPitting corrosion and structural reliability of corroding RC structures: Experimental data and probabilistic analysis
A stochastic analysis is developed to assess the temporal and spatial variability of pitting corrosion on the reliability of corroding reinforced concrete (RC) structures. The structure considered herein is a singly reinforced RC beam with Y16 or Y27 reinforcing bars. Experimental data obtained from corrosion tests are used to characterise the probability distribution of pit depth. The RC beam ...
متن کاملBridge Deck Replacement for Minimum Expected Cost Under Multiple Reliability Constraints
The present paper investigates the effect of limit state selection ~strength versus serviceability! on bridge deck life-cycle costs and thus on optimal repair strategies. Such a comparison may then help determine whether safety or functionality ~or both! are important criteria when optimizing bridge life-cycle performance and costs. The structural element under consideration is a reinforced con...
متن کاملTOPOLOGY OPTIMIZATION OF PRETENSIONED CONCRETE BEAMS CONSIDERING MATERIAL NONLINEARITY
In this paper, the bi-directional evolutionary structural optimization (BESO) method is used to find optimal layouts of 3D prestressed concrete beams. Considering the element sensitivity number as the design variable, the mathematical formulation of topology optimization is developed based on the ABAQUS finite element software package. The surface-to-surface contact with a small sliding between...
