This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Punching shear capacity of reinforced concrete slabs is influenced by the following material properties: concrete compressive strength, flexural reinforcement ratio, inclusion of steel fibers in the concrete mix, and the reinforcing steel yield strength. A review of current finite element analysis models reveals that a unified approach to include all of these variables into one coherent model does not exist. This thesis presents a finite element model capable of making accurate predictions on the ultimate punching shear load and load - deflection response of a reinforced concrete slab. The model simulates the nonlinear constitutive properties of reinforced concrete by proposing a robust model to represent the behavior through the Concrete Damaged Plasticity (CDP) constitutive model. The thesis defines the parameters for the CDP model in a finite element analysis and develops an expression to mitigate mesh size dependency. A tension - stiffening model is proposed using an exponential decay expression with variables to account for varying concrete compressive strength, flexural reinforcement ratio, inclusion of steel fibers in the concrete mix, and the reinforcing steel yield strength. The model is calibrated using a series of experimental data from the literature and validated by successfully replicating the punching shear behavior of experimental specimens data from the literature.

Available in PDF, EPUB and Kindle. Book excerpt: In Finite Element Design of Concrete Structures: practical problems and their solutions the author addresses this blind belief in computer results by offering a useful critique that important details are overlooked due to the flood of information from the output of computer calculations. Indeed, errors in the numerical model may lead in extreme cases to structural failures as the collapse of the so-called Sleipner platform has demonstrated.

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.

This book was released on 2008-01-01 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-linear computer analysis methods have seen remarkable advancement in the last half-century. The state-of-the-art in non-linear finite element analysis of reinforced concrete has progressed to the point where such procedures are close to being practical, every-day tools for design office engineers. Non-linear computer analysis procedures can be used to provide reliable assessments of the strength and integrity of damaged or deteriorated structures, or of structures built to previous codes, standards or practices deemed to be deficient today. They can serve as valuable tools in assessing the expected behaviour from retrofitted structures, or in investigating and rationally selecting amongst various repair alternatives. fib Bulletin 45 provides an overview of current concepts and techniques relating to computer-based finite element modelling of structural concrete. It summarises the basic knowledge required for use of nonlinear analysis methods as applied to practical design, construction and maintenance of concrete structures, and attempts to provide a diverse and balanced portrayal of the current technical knowledge, recognizing that there are often competing and conflicting viewpoints. This report does not give advice on picking one model over another but, rather, provides guidance to designers on how to use existing and future models as tools in design practice, in benchmarking of their models against established and reliable test data and in selecting an appropriate safety factor as well as recognising various pitfalls. fib Bulletin 45 is intended for practicing engineers, and therefore focuses more on practical application and less on the subtleties of constitutive modelling.

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.

Download or read book Finite Element Modeling of Punching Shear Behavior of Ultra High Performance Fiber Reinforced Concrete Slabs Considering Effect of Fiber Orientation written by Thuc Nhu Nguyen and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study represents a numerical study on the punching shear behavior of ultra-high performance steel fiber reinforced concrete (UHPFRC) slabs without shear reinforcement, particularly considering the effect of fiber orientation, validated by experimental results. In recent decades, ultra-high performance steel fiber reinforced concrete (UHPFRC) has been a new achievement in concrete technology. Due to its superior mechanical properties, civil engineers can address the problem of punching shear of thin slabs that are currently widely used in buildings. By processing some studies, researchers have found that the strength capacity of the material before cracking and the post-cracking resistance strongly depend on the orientation of the fibers, which heavily rely on the casting direction and casting method. While most of previous studies focused on the effect on the behavior of beams, the present research particularly considers how the casting procedures as well as the volume content of the fiber affect the punching shear behavior of flat slabs.Based on models from the previous research and this research’s experimental results, constitutive model of material was proposed to capture the effects of fiber orientation. Different parts of the slab according to different distances from casting positions produce different fiber orientations, and lead to different material models, particularly tensile constitutive models. The material models were applied to finite element analysis in ABAQUS/Explicit, using Concrete Damage Plasticity model to simulate the punching shear behavior of the flat slabs. The appropriation of proposed material models and finite element modeling procedure were validated by comparing to experimental results. Consequently, these models can be used further to consider the effect of fiber orientation in future researches and utilizations of UHPFRC structures.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was the development of a procedure in GT STRUDL to design reinforced concrete flat plate systems based on the results of finite element analysis. The current state-of-practice of reinforced concrete flat plate design was reviewed, including the ACI direct design and equivalent frame techniques, the yield line method, and the strip design method. The principles of these methods along with a critical evaluation of their applicability and limitations were presented as motivation for a finite element based design procedure. Additionally, the current state-of-the-art of flat plate design based on finite element results was presented, along with various flat plate modeling techniques. Design methodologies studied included the Wood and Armer approach, based on element stress resultants, and the resultant force approach, based on element forces. A flat plate design procedure based on the element force approach was embodied in the DESIGN SLAB command, which was implemented in GT STRUDL. The DESIGN SLAB command provides the user the ability to design a slab section by specifying a cut definition and several optional design parameters. The procedure determines all nodes and elements along the cut, computes the resultant moment design envelope acting on the cross-section, and designs the slab for flexure in accordance with provisions of ACI 318-02. Design examples presented include single-panel flat plate systems with various support conditions as well as multi-panel systems with regular and irregular column spacing. These examples allowed for critical comparison with results from experimental studies and currently applied design methods in order to determine the applicability of the implemented procedure. The DESIGN SLAB command was shown to produce design moments in agreement with experimental data as well as conventional design techniques for regular configurations. The examples additionally showed that when cuts were not oriented orthogonally to the directions of principle bending, resulting designs based on element forces could significantly under-reinforce the cross-section due to significant torsional effects.
