Available in PDF, EPUB and Kindle. Book excerpt: Existing structures represent a heterogeneous category in the global built environment as often characterized by the presence of archaic materials, damage and disconnections, uncommon construction techniques and subsequent interventions throughout the building history. In this scenario, the common linear elastic analysis approach adopted for new buildings is incapable of an accurate estimation of structural capacity, leading to overconservative results, invasive structural strengthening, added intervention costs, excessive interference to building users and possible losses in terms of aesthetics or heritage values. For a rational and sustainable use of the resources, this book deals with advanced numerical simulations, adopting a practical approach to introduce the fundamentals of Finite Element Method, nonlinear solution procedures and constitutive material models. Recommended material properties for masonry, timber, reinforced concrete, iron and steel are discussed according to experimental evidence, building standards and codes of practice. The examples examined throughout the book and in the conclusive chapter support the analyst’s decision-making process toward a safe and efficient use of finite element analysis. Written primarily for practicing engineers, the book is of value to students in engineering and technical architecture with solid knowledge in the field of continuum mechanics and structural design.

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.
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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Extended Finite Element Method provides an introduction to the extended finite element method (XFEM), a novel computational method which has been proposed to solve complex crack propagation problems. The book helps readers understand the method and make effective use of the XFEM code and software plugins now available to model and simulate these complex problems. The book explores the governing equation behind XFEM, including level set method and enrichment shape function. The authors outline a new XFEM algorithm based on the continuum-based shell and consider numerous practical problems, including planar discontinuities, arbitrary crack propagation in shells and dynamic response in 3D composite materials. Authored by an expert team from one of China's leading academic and research institutions Offers complete coverage of XFEM, from fundamentals to applications, with numerous examples Provides the understanding needed to effectively use the latest XFEM code and software tools to model and simulate dynamic crack problems

This book was released on 2017 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most reinforced concrete (RC) design provisions have been developed on the basis of experimental data involving isolated and highly-idealized structural elements. As a result, many of the RC-related design provisions currently used are unsuitable for providing accurate assessments of RC structural systems. Thus, there is a need for practical modeling procedures that can be used to reliably investigate the performance of real-world RC structures. Such tools can aid in the assessment of structures that are exhibiting distress, that employ atypical or code-deficient design details, are in need of retrofit or modification, or simply are of a type that fall outside of traditional design provisions. This dissertation presents the development and application of nonlinear finite element analysis procedures employing cracked concrete material modeling based on the formulations of the Disturbed Stress Field Model (DSFM). These procedures are used to investigate the punching shear performance of RC flat plates, an area where design is typically done in a highly-idealized manner; yet, structure performance may be greatly impacted by system-level response. Nonlinear finite element modeling was done using two approaches. Three-dimensional solid continuum modeling was found to provide good response estimates for slab-column connection specimens under concentric shear loading and effectively captured the effects of different parameters on punching performance: reinforcement ratio, column size, and slab thickness. The validated solid modeling procedure was used to perform a parametric study on the influence of boundary conditions on the response of multi-bay flat plate structures. The findings indicated that RC slab systems are likely to have load capacities that are greater than that inferred from isolated connection elements. Alternatively, RC slab modeling was also done using computationally-efficient layered shell finite elements that accommodate through-thickness shearing effects. A simple sectional analysis modification procedure was used to incorporate strength enhancements within slab disturbed regions and the proposed procedure was shown to be capable of providing reasonable estimates for the punching shear strength of RC slab-column connections and slab subsystems. Predicted load-displacement curves and failure modes were in reasonable agreement with test data and provided estimates that were similar to those obtained using costlier solid modeling techniques
