Available in PDF, EPUB and Kindle. Book excerpt: A smeared crack approach to fracture of concrete in mode I was implemented in the finite element program ADINA. Nonlinear concrete elements with tensile cracking were modified to include tensile strain softening. When an element at an integration point cracks, the stiffness perpendicular to the crack is reduced to zero and the tensile stress across it is set as a function of the crack opening. Equilibrium iterations were implemented to redistribute stress. Two- and three-dimensional models of a single edge notched beam in three-point bending were analyzed and compared to experimental results with good agreement. The analytical representation of mixed mode fracture was also addressed. The mechanisms of shear transfer across a crack were detailed, and the rough crack model, relating shear stress to crack opening, is presented with discussions on orientation of successive crack planes, tensorial invariance, and snap-back phenomena. Problems are identified with modeling bond at the concrete/reinforcement interface and its effect on crack patterns. Keywords: Fracture mechanisms; Crack propagation; Mixed mode; Shear; Bond tension; Softening; Fracture energy; ADINA computer programs. (SDW).

Book Synopsis Analysis of Reinforced Concrete Beams Subjected to Fire by : Bruce R. Ellingwood
Download or read book Analysis of Reinforced Concrete Beams Subjected to Fire written by Bruce R. Ellingwood and published by . This book was released on 1976 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods for analytically predicting the behavior of simply supported reinforced concrete beams subjected to fire are presented. This is generally a two-step process involving a thermal analysis followed by a stress analysis. This study emphasizes the latter, wherein the determination of moment-curvature-time relationships for the beam cross section incorporates the temperature-dependent strength degradation in the steel and concrete as well as thermal and creep strains. The sensitivity of the predictions to various phases of analytical modeling is investigated to establish the parameters most important for the prediction of beam behavior and to indicate where additional data should be gathered. A comparison of predicted behavior with that observed in fire tests shows excellent agreement when realistic reinforcement temperature histories are used.

Book Synopsis Numerical and Analytical Modeling of Concrete Confined with Frp Wraps by : Omkar Tipnis

Available in PDF, EPUB and Kindle. Book excerpt: This thesis is intended at studying and comparing empirical models that have been proposed for the modeling of the stress-strain response of a FRP confined concrete subjected to axial load. An attempt has been made to model the experimental set up for the compression test of a concrete cylinder confined with FRP sheet in AbaqusCAE. The results so obtained have been compared and analyzed against the experimental test results & the results obtained from a chosen mathematical model (Modified Lam & Teng). An attempt was made to create a new material model in Opensees that follows the chosen mathematical model. However, this was not achieved due to the reasons that will be explained in the later sections.Reinforced concrete confined with steel is typically designed by considering the Manders model (Mander et al., 1988), which assumes a constant confining pressure. This is true with the case of steel as it is a ductile material and one assumes the steel to be yielded. However with the case of FRP jackets, this is not true. FRP is a linear elastic and brittle material and does not yield, which makes the Manders model inaccurate for its analysis. Many models have been proposed which take into account the increasing confining pressure due to the FRP wrap. A comparative study of the constitutive models proposed for FRP confined reinforced concrete has been done in this study.Finally after a series of numerical interpretations of different specimens and their comparison with the experimental data, the utility and accuracy of the new modified Lam & Teng's model was validated. The validation process included comparison and analytical data obtained via finite element simulation in Abaqus, empirical model results and the experimental data.The objective is achieved and restricted within the following scope of study:1)Literature review to identify and choose the most relevant models for modeling of concrete confined with fiber reinforced polymers in compression.2)Modelling and finite element analysis of the confined concrete compression test in AbaqusCAE.3)Developing the stress-strain curve from several proposed empirical model (Modified Lam & Teng).4)Survey of experimental data on confined concrete with FRP in order to generate an experimental database.5)Comparison of the analytical results in order to define the strengths and limitations of the empirical model chosen to study.6)Validation of the model chosen and a study on its relevance for use in typical bridge columns retrofitted with FRP jackets.7)Proposing changes to the empirical model for more accurate results.8)Validate the effects of the proposed changes.

The 1978 Model Code has had a considerable impact on the national design codes in many countries. In particular, it has been used extensively for the harmonisation of national design codes and as basic reference for Eurocode 2. The 1990 Model Code provides comprehensive guidance to the scientific and technical developments that have occurred over the past decade in the safety, analysis and design of concrete structures. It has already influenced the codification work that is being carried out both nationally and internationally and will continue so to do.
Book Synopsis Finite Element Analysis of Prestressed Concrete Structures Using Post-Tensioning Steel by : Yu Huang
Download or read book Finite Element Analysis of Prestressed Concrete Structures Using Post-Tensioning Steel written by Yu Huang and published by Cambridge Scholars Publishing. 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.

Book Synopsis Analytical Modeling of Cyclic Shear by : Kristijan Imre Kolozvari

Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted to develop a modeling approach that integrates flexure and shear interaction under cyclic loading conditions to obtain reliable predictions of inelastic responses of reinforced concrete (RC) structural walls. The proposed modeling approach incorporates cyclic RC panel constitutive behavior based on an interpretation of the fixed-strut-angle approach into a two-dimensional fiber-based macroscopic model. Coupling of axial and shear responses under cyclic loading is achieved at the fiber (panel) level, which further allows coupling of flexural and shear responses at the element level. The sensitivity of model results to various modeling parameters (e.g., material constitutive parameters and modeling parameters), wall configuration parameters (e.g., aspect ratio, boundary and web reinforcement ratios), and response parameters (levels of wall axial load and shear) was investigated to demonstrate the ability of the model to predict the behavior or RC walls for a broad range of conditions. The proposed analytical model was validated and calibrated against experimental results obtained from six large-scale, heavily instrumented, cantilever structural wall specimens characterized with different aspect ratios (1.5, 2.0 and 3.0), axial load levels (0.0025 A_g_f'_c, 0.07 A_g_f'_c and 0.10 A_g_f'_c) and wall shear stress levels (between approximately 4 and 8 [square root]"f'_c) psi) tested under combined constant axial load and reversed cyclic lateral loading applied at the top of the wall. Comparisons of experimental and analytical model results for moderately slender RC walls (aspect ratio 1.5 and 2.0) revealed that the model successfully captures experimentally observed interaction between nonlinear shear and flexural deformations under cyclic loading and predicts lateral strength and stiffness that is within 10% of experimentally measured values. In addition, the magnitudes and relative contributions of shear and flexural deformations along the wall height were predicted closely at low and moderate drift levels, whereas at drift levels larger than 2.0%, model results were within 25% of experimentally measured deformation components. As well, localized nonlinear responses such as vertical tensile and compressive strains and wall rotations at the wall base were well predicted by the model. The model results were less accurate for the slender (aspect ratio 3.0) RC wall specimen in terms of relative contributions of shear and flexural deformations and magnitudes of compressive strains. Demonstrated model sensitivity to parameters of the implemented RC panel behavior suggested the need for calibration of these parameters for reliable predictions of nonlinear wall behavior. Given the limited model calibration performed in this study, additional work is needed, particularly for slender RC walls where preliminary results were less accurate. Finally, the implementation of the model into a publicly available computational platform is required to enable more detailed system level studies and future model development.

Book Synopsis Additional Finite Element Method for Analysis of Reinforced Concrete Structures at Limit States by : Ermakova A.V.
Download or read book Additional Finite Element Method for Analysis of Reinforced Concrete Structures at Limit States written by Ermakova A.V. and published by Издательство АСВ. This book was released on 2012 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presents the theoretical basis of Additional Finite Element Method (AFEM), which is a variant of the Finite Element Method (FEM) for analysis of reinforced concrete structures at limit state. AFEM adds to the traditional sequence of problem by FEM the units of the two well-known methods of the structural design: method of additional loads and limit state method. The problem is solved by introduction of ideal failure models and additional design diagrams formed from additional finite elements, where each AFE describes the limit state reached by the main element. The main relations defining the properties of AFEs as well as the examples of the use of Additional Finite Element Method for analysis of reinforced concrete structures at limit state are given in the work too.
