Abstract
Steel bridge piles and offshore structural columns are subjected to a variety of Environmental interactions and acted upon by various dead and live loads throughout their life cycle. These structures are constantly exposed to deterioration effecting their usability. Rehabilitation and maintenance of these structural components improves the integrity and durability of these structures to safely support the axial loads the members are intended to carry. In the conducted study a numerical simulation using the Abaqus Finite Element software package is performed to investigate the effect of the Carbon Fiber Reinforced Polymers (CFRPs) in strengthening the corroded piles. Incorporated composites are rustproof, more economical to use, and relatively easier to incorporate in the rehabilitation process. In the developed models, various shape and size deficiencies are created at critical locations on the columns and a numerical study is conducted to determine the efficiency and increase in the load carrying capacity of the columns reinforced with composite layers. Sample produced finite element simulation models and the corresponding results for deteriorated columns with circular and square cross-sectional areas are included in the presentation to clearly illustrate the utility of the developed procedures.
The results from such performed investigations can aid in finding more efficient methods in retrofitting and strengthening structural components using composites and other reinforcements, to better sustain the applied loads. These findings can be of interest to state and national agencies since the developed methods offer an economical option for repairing the deteriorated or damaged structural members rather than replacing them. The development of the simulation models for investigating the effectiveness of the implemented rehabilitation procedures is an economical and efficient alternative approach for determining the efficacy of the proposed retrofitting systems. Building and testing full-scale physical models of the columns in a laboratory setting is expensive and requires various experimental instrumentations.
Program Description
In the conducted study a numerical simulation using the Abaqus Finite Element Package is performed to investigate the effect of the Carbon Fiber Reinforced Polymers in retrofitting the corroded structural columns. In this study, various shape and size deficiencies are considered to determine the increase in the load carrying capacity of the reinforced columns.
