Book Nonlinear Finite Element Modeling of RC Beams Strengthened with Prestressed NSM FRP Laminates

Download or read book Nonlinear Finite Element Modeling of RC Beams Strengthened with Prestressed NSM FRP Laminates written by Yubraj Pandey and published by . This book was released on 2017 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the parametric study of nonlinear Finite Element Analysis (FEA) modeling of Reinforced Concrete (RC) beams prestressed with Near-Surface Mounted (NSM) FRP. FEA model was validated with the experimental beam results available in the literature to determine the accuracy. Parameters considered were steel and laminates reinforcement ratios, various steel and FRP materials properties (Normal Modulus (NM), High Modulus (HM) and Ultra-High Modulus (UHM)), and FRP types (Basalt Fiber Reinforced Polymer (BFRP), Glass Fiber Reinforced Polymer (GFRP) and Carbon Fiber Reinforced Polymer (CFRP)) under various prestressing conditions. The RC beams were strengthened with FRP laminates which were prestressed by 20, 30, 40% and were compared to the control beam (0% prestressing).The temperature equivalent to the prestressing force was applied to the FRP laminates. Based upon these prestressing levels, the load at yield initiation, ultimate load at failure and ductility index of the beam were determined. From finite element analysis of RC beam results, the application of the prestressing had significantly increased the load at the yield point. However, the percentage increase of ultimate load was low as compared to non prestressed beam. The load versus displacement curves of beams demonstrated a reduction in ductility as the prestressing level was increased. The optimum prestressing level found to be 30% for all parameters while the FRP reinforcement ratio had the maximum effect in load carrying capacity.

Book Finite Element Modeling of Reinforced Concrete Beams Externally Strengthened by FRP Composites

Download or read book Finite Element Modeling of Reinforced Concrete Beams Externally Strengthened by FRP Composites written by Tanarat Potisuk and published by . This book was released on 2000 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three-dimensional finite element models are developed to simulate the behavior of four fill-scale reinforced concrete beams. The beams are constructed with different fiber-reinforced polymer (FRP) strengthening schemes, and are modeled using ANSYS, a commercially available finite element analysis program. The experimental beams replicate the transverse beams of the Horsetail Creek Bridge, and were constructed and tested at Oregon State University. The finite element models use a smeared cracking approach for the concrete and three-dimensional layered elements to model the FRP composites. It was found that the finite element models could effectively simulate the behavior of the full-scale beams. Results obtained from the finite element analysis are presented and compared with the experimental data from the full-scale beam tests through the linear and nonlinear ranges up to failure. Comparisons are made for load-strain plots, load-deflection plots, first cracking loads, loads at failure, and crack patterns at failure. The results from the finite element analysis show good agreement with those from the experimental data and support hand calculation predictions for the experiment very well. The crack patterns at failure predicted by the finite element program strongly corroborate the failure modes observed for the full-scale beam tests. Recommendations for finite element modeling improvement are included.

Book Finite Element Analysis of an Intentionally Damaged Prestressed Reinforced Concrete Beam Repaired with Carbon Fiber Reinforced Polymers

Download or read book Finite Element Analysis of an Intentionally Damaged Prestressed Reinforced Concrete Beam Repaired with Carbon Fiber Reinforced Polymers written by David A. 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.

Book Fiber Reinforced Polymer Strengthening of Steel Beams

Download or read book Fiber Reinforced Polymer Strengthening of Steel Beams written by Bibek Regmi Bagale and published by . This book was released on 2019 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fiber reinforced polymer (FRP) strengthening has been widely used for concrete structures. However, limited studies have been conducted on FRP application to steel structures. The use of FRP materials to retrofit steel members is an effective replacement for welded or bolted steel plates and offer high strength-to-weight ratio, resilience to environmental degradation, and a robust fatigue performance. Although the application of FRP to retrofit steel structures have been on the rise in recent years, their behavior under various loading conditions have not been fully explored. The objective of this study is to analyze FRP retrofitting of steel beams using finite element analysis (FEA) modeling technique. FEA model of a steel beam strengthened with fiber reinforced polymer (FRP) laminates was developed using ANSYS Mechanical APDL finite element software program. The FEA models of steel beams subjected to monotonic static and fatigue loads were validated by comparing the FEA and experimental results of existing studies in the literature and they were in good agreement. Parametric studies were then performed on the validated models to investigate the behavior of FRP strengthened steel beams subjected to static and dynamic loadings. Under static load, damaged and undamaged steel beams were retrofitted with carbon fiber reinforced polymer (CFRP) to examine the effect of bond length and transverse anchorages on flexural behavior and failure modes. The CFRP laminate provided an increase in the flexural capacity for the undamaged and damaged beams by approximately 1.7 and 3 times respectively as compared to their counterpart control beams. The FRP laminate effective bond length under static loading condition was found to be 2/5 of the simply supported span length of the steel beam. Furthermore, with the addition of anchorages, the flexural capacity was increased by 1.5 times and the mode of failure changed from the debonding to rupture. Basalt fiber reinforced polymer (BFRP) is a newer form of FRP material which is extracted from natural sources and is considered an environment friendly option in lieu of CFRP material. BFRP application to steel beams were investigated in this study for both static and dynamic cases. Under dynamic loading, different FRP material types such as CFRP, BFRP and Aramid fiber reinforced polymer (AFRP) were studied. A regression analysis was performed to generate new S-N curves and formulas were proposed to predict the fatigue life of BFRP and AFRP strengthened steel beams.
