Book excerpt: Reinforced concrete buildings built prior to the enactment of modern seismic provisions are vulnerable when subjected to high-magnitude earthquakes since they lack the capacity to properly dissipate the energy associated with the ground excitation. Therefore, this research aims to investigate the benefits of Buckling-Restrained Braces (BRBs) as a retrofit technique for accommodating seismic demands in seismically deficient reinforced concrete frames, the dominant structural system of pre-1970s construction. The efficiency of Superelastic-Shape Memory Alloys (SE-SMA) as the core material of the BRB is also evaluated. Improvements in lateral strength capacity and residual displacements of the SMA-BRB retrofitted frames are assessed against a previously tested bare concrete frame and frames retrofitted with BRBs incorporating stainless steel and chrome-molybdenum steel core bars. Reverse cyclic finite-element modelling of the frames was conducted with VecTor2, and the numerical models were validated through experimental results present in the literature. The validated numerical models were further modified to address deficiencies in the original BRB design by including improvements in restraining of the buckling. The SMA-BRB provided lateral strength comparable to the modified steel BRB models with enhancements in ductility capacity. Notably, the SMA-BRB system did not accumulate additional residual displacements beyond those experienced by the bare frame alone. Therefore, the reduction in residual displacements, in comparison to conventional steel core BRB materials, illustrates one of the main benefits of SMA bars, leading to a viable and efficient alternative to increase the seismic performance and reduce damage in structural elements located in high seismic zones. Furthermore, nonlinear time-history analyses are conducted. Earthquake records that simulate design earthquakes for the cities of Montreal and Vancouver were selected for the dynamic loading. At the end of the thesis, an optimized BRB design is provided in which the full capacity of the core bars is achieved since localized buckling is minimized.

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 2020-04-22 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, numerical computation has become one of the most vigorous tools for scientists, researchers and professional engineers, following the enormous progress made during the last decades in computing technology, in terms of both computer hardware and software development. Although this has led to tremendous achievements in computer-based structural engineering, the increasing necessity of solving complex problems in engineering requires the development of new ideas and innovative methods for providing accurate numerical solutions in affordable computing times. This collection aims at providing a forum for the presentation and discussion of state-of-the-art innovative developments, concepts, methodologies and approaches in scientific computation applied to structural engineering. It involves a wide coverage of timely issues on computational structural engineering with a broad range of both research and advanced practical applications. This Research Topic encompasses, but is not restricted to, the following scientific areas: modeling in structural engineering; finite element methods; boundary element methods; static and dynamic analysis of structures; structural stability; structural mechanics; meshless methods; smart structures and systems; fire engineering; blast engineering; structural reliability; structural health monitoring and control; optimization; and composite materials, with application to engineering structures.

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.

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.

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.
