This book was released on 2020-05-28 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book details the theory and applications of finite element (FE) modeling of post-tensioned (PT) concrete structures, and provides the updated MATLAB code (as of 2019). The challenge of modeling PT prestressed concrete structures lies in the treatment of the interface between the concrete and prestressing tendons. Using MATLAB, this study develops an innovative nonlinear FE formulation which incorporates contact techniques and engineering elements to considerably reduce the need of computational power. This FE formulation has the ability to simulate different PT frame systems with fully bonded, fully unbonded or partially bonded tendons, as well as actual sliding behavior and frictional effects in the tendons. It also allows for the accurate simulation of anchor seating loss.

Available in PDF, EPUB and Kindle. Book excerpt: Reinforced/pre-stressed (RC/PC) concrete is one of the most commonly used construction materials. This composite material demonstrates a highly non-linear behaviour caused by, cracking, crushing, agregate interlock, bond slip, dowel action, shrinkage, creep, etc. Because the bahviour of reinforced/pre-stressed concrete invloves so many non-linear phenomena interacting with one other, the formulate of rational analytical procedures to describe this behaviour is very dificult. Since the advent of the computer, powerful methods of analysis such as the finite element method and stiffness matrixmethod have been implemented to study and develop analytical solutions for the non-linear phenomena. However, the succes of such analysis depends on a through understanding and modelling of the composite material behaviour. This study describes the development of a non-linear computer code used to predict the non-linear response of reinforced/pre-stresses concrete beams that are subjected to acombined axial force and bending moment. The study discusses a new simplified approach, whereby the non-linear response is captured via a series of sequentlly linear steps. The finite element approach with the stiffness matrix method were used to model the beam element structure and generate its stiffness matrix. A monotonic empirical model for the concrete's stress-strain curve has been implemented to predict both ascending and descending parts of the curve. An idealized bi-linear elasto-plastic in tension and compression model has been assumed for reinforcing and pre-stressing steel. Concrete and reinforcing/pre-stressing steel are represented by separate algorithms, which when combined together, describe the behaviour of the composite reinforced/pre-stressed concrete material. The newton-Raphson concepts has been implemented in the interaction technique to satisfy equilibrium and compatibility conditions. Finally, correlation studies between analytical and experimental results have been carried out with the objective to establish the validity of the proposed model. The verification of the program started by comparing the predictions of the non-linear response for a reinforced concrete beam with that of the results which have been obtained experimentally, ang by using the finite element method for the same beam. The comparison was made for the failure load, yielding load and load-deflection relation. Further more, a 6.0m reinforced concrete beam has been investigated in detail as a simply supported and as a fixed supported beam, 2.5 m presstressed concrete beam also investigated in details. The comparison study shows that the prediction from the developed program correlate well with other results. The investigated beam show that the program results are in complete agreement with the assumptions and models considered to develop the code. The results clearly showed the magnitude and locations of cracking, yielding, ultimate load, failure load and ductility requirements. The program may be used as a tool to do parametric study on the behaviour of reinforced and prestressed concrete stuctures.

Brighton and published by . This book was released on 2011 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the existing bridges are in need of repair and strengthening due to various reasons including design flaws, fatigue and deterioration of steel reinforcement, increase in traffic volume, and accidental impact loads during collisions between vehicles and bridge girders or piers. The use of fiber reinforced polymer (FRP) materials to repair and strengthen the deficient infrastructures has become very popular due to FRP's well known advantages such as high strength-to-weight ratio, corrosion resistance, light weight, and ease of applications. This paper presents a review of existing experimental investigations and field applications of FRP-strengthened reinforced concrete structures. Various FRP retrofit techniques are also discussed. A Finite Element Model (FEM) of a prestressed reinforced concrete beam is modeled based off an experimentally tested beam. The model is intentionally damaged by cutting two prestressing strands and one mild steel bar. The beam is repaired with three layers of Carbon Fiber Reinforced Polymer (CFRP) to recover the original design strength of the beam.
