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.

This book was released on 2018 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study involves flexural strengthening of reinforced concrete (RC) beams by prestressed fiber reinforced polymers (FRP) and iron-based shape memory alloys (Fe-SMAs) using near surface mounted (NSM) technique. The ANSYS Program Design Language (APDL) was employed to generate a finite element analysis (FEA) beam model which was validated using the data from an existing experimental study in the literature. The beam FEA model and experimental results were in a good agreement. Parameters considered were internal and external reinforcement ratios, bond length, concrete strength, and NSM rod material type under three pre-stressing levels (20%, 30%, 40%). The influence of these parameters on the beams' load carrying capacity, midspan displacement, ductility index, and failure mode were determined. The results showed that at larger prestressing level, the beam had higher cracking, yielding, and ultimate load capacities. However, the displacement was decreased and consequently, the ductility index reduced as pre-stressing level increased. Furthermore, the Fe-SMA material was able to provide significant ductility. The optimum prestressing level can be identified based on the primary RC beams' design criteria to either improve load or displacement capacity or both.

Available in PDF, EPUB and Kindle. Book excerpt: The first textbook on the design of FRP for structural engineering applications Composites for Construction is a one-of-a-kind guide to understanding fiber-reinforced polymers (FRP) and designing and retrofitting structures with FRP. Written and organized like traditional textbooks on steel, concrete, and wood design, it demystifies FRP composites and demonstrates how both new and retrofit construction projects can especially benefit from these materials, such as offshore and waterfront structures, bridges, parking garages, cooling towers, and industrial buildings. The code-based design guidelines featured in this book allow for demonstrated applications to immediately be implemented in the real world. Covered codes and design guidelines include ACI 440, ASCE Structural Plastics Design Manual, EUROCOMP Design Code, AASHTO Specifications, and manufacturer-published design guides. Procedures are provided to the structural designer on how to use this combination of code-like documents to design with FRP profiles. In four convenient sections, Composites for Construction covers: * An introduction to FRP applications, products and properties, and to the methods of obtaining the characteristic properties of FRP materials for use in structural design * The design of concrete structural members reinforced with FRP reinforcing bars * Design of FRP strengthening systems such as strips, sheets, and fabrics for upgrading the strength and ductility of reinforced concrete structural members * The design of trusses and frames made entirely of FRP structural profiles produced by the pultrusion process

Download or read book Experimental and Numerical Study of RC Beams Strengthened in Flexure with Bolted bonded AA Plates written by Omar Raed Abuodeh and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Reinforced Concrete (RC) members are susceptible to deterioration due to many factors. Externally bonded reinforcement (EBR) such as fiber-reinforced polymers (FRP), had emerged as one of the proven techniques for flexural strengthening and retrofitting of RC members. This is due to its practicality and structural effectiveness; however there are shortcomings that include premature de-bonding/de-lamination failure or brittle FRP rupture failures. The use of mechanically anchored Aluminum Alloy (AA) plates instead has the potential of overcoming these drawbacks by providing both strength and ductility while influencing the failure modes. In this project, 16 RC beams were prepared, one beam was left unstrengthened (CB), one was strengthened with AA plate using epoxy only (CBE), and 14 beams were strengthened with AA plates with different bolt sizes, spacing, bolt layout and epoxy. The specimens were tested to failure and all specimens with bolted AA plates exhibited approximately 30% increase in strength accompanied with drastic increase in ultimate ductility (56.5%) and failure ductility (84.1%) compared to the control beam with epoxy (CBE). It is concluded that the implementation of a hybrid anchorage system (i.e., bolts with epoxy) in retrofitting applications serves as a viable option for fixing AA plates to RC beams. Furthermore, nonlinear finite element (FE) models for all specimens were developed using validated constitutive laws for capturing the nonlinear properties of the materials. Contour plots and concrete cracking patterns were generated to monitor the stress and cracking propagation for each model. The FE predictions closely resemble that of the experimental results in terms of load-deflection, cracks patterns and failure modes. This validated the use of FE as a simulation tool for further investigating the behavior of RC beams strengthened with externally bonded and bolted AA plates."--Abstract.
