Book Description
This study presents a framework for multi-platform analysis and hybrid (experimental-analytical) simulation of reinforced concrete structures. In this approach, each potentially critical member, based on its mechanical characteristics, is modelled using the most suitable finite element analysis tool or is represented with a test specimen, while the rest of the structure is modelled with computationally fast global analysis software. The interaction between substructure modules is fully considered by satisfying compatibility and equilibrium requirements. The framework is based on object-oriented methodology and uses a standardized data exchange format, facilitating addition of new analysis tools or test equipment. The effectiveness of the framework is evaluated by several verification examples including analysis of structures repaired with fibre-reinforced polymer sheets. The multi-platform analysis computes the behaviour of structures with a level of accuracy that was previously difficult to achieve with most single-platform analysis software. In addition, a new interface element, named F2M, is introduced to connect layered beam elements to membrane elements. Compared to existing methods, the F2M element provides more realistic stress distributions and allows for transverse expansion at the connection section between substructures. The accuracy of the proposed element is verified through mixed-dimensional modelling of a series of beam specimens presented in the literature. A small-scale experimental program was conducted using a six degree-of-freedom hydraulic testing equipment to verify the hybrid simulation framework and provide additional data for small-scale testing of shear-critical reinforced concrete frames. The physical models were 1/3.23-scale representations of a beam and two columns. A multi-platform modelling technique was employed to analyze the remainder of the frames. The hybrid simulation results were compared against those obtained from a similar large-scale test and finite element analyses. The study found that, with proper precautions, small-scale hybrid testing can sufficiently well simulate the behaviour of shear-critical frames. However, to draw general conclusions, additional test data are required.

Book Description
Analytical Approaches for Reinforced Concrete presents mathematically-derived theories and equations for RC design and construction. The book applies deductive reasoning, logic and mathematics to RC. Laying out, deductively, the principles of RC, it encourages researchers to re-imagine and innovate using a solid conceptual framework. Sections consider the reasoning behind key theories, as well as problems that remain unsolved. The title presents key ideas in simple language and illustrates them clearly to help the reader grasp difficult concepts and develop a solid foundation, grounded in mathematics, for further study and research. The book is future-oriented, demonstrating theories that are applicable not only to conventional reinforced concrete members, but also to the envisaged structures of tomorrow. Such developments will increasingly require a deep, deductive understanding of RC. This title is the first of its kind, presenting a fresh analytical approach to reinforced concrete design and construction. Takes an analytical approach to reinforced concrete using mathematics and deduction Lays out the reasoning behind key theories and models in reinforced concrete design and construction Encourages researchers-new and established- to re-imagine and innovate using a solid conceptual framework Presents difficult concepts that are clearly and analytically presented with accompanying illustrations Looks forward to the use of reinforced concrete in the complex structures of the future

Book Description
A comprehensive review of the material behavior of concrete under dynamic loads, especially impact and impuls, opens the volume. It is followed by a summary of the various analytical tools available to engineers interested in analyzing the nonlinear behavior of reinforced concrete members for dynamic load. These range from relatively simple and practice-oriented push-over analysis to sophisticated layered finite element models. Important design-related topics are discussed, with special emphasis on performance of concrete frames subjected to seismic loads. The significance of modern software systems is recognized by including extensive examples. For readers not current in dynamic analysis methods, an appendix contains a review of the mathematical methods most commonly used for such analysis.

Book Description
This book provides state of the art coverage of important current issues in the analysis, measurement, and monitoring of the dynamic response of infrastructure to environmental loads, including those induced by earthquake motion and differential soil settlement. The coverage is in five parts that address numerical methods in structural dynamics, soil–structure interaction analysis, instrumentation and structural health monitoring, hybrid experimental mechanics, and structural health monitoring for bridges. Examples that give an impression of the scope of the topics discussed include the seismic analysis of bridges, soft computing in earthquake engineering, use of hybrid methods for soil–structure interaction analysis, effects of local site conditions on the inelastic dynamic analysis of bridges, embedded models in wireless sensor networks for structural health monitoring, recent developments in seismic simulation methods, and seismic performance assessment and retrofit of structures. Throughout, the emphasis is on the most significant recent advances and new material. The book comprises extended versions of contributions delivered at the DE-GRIE Lab Workshop 2014, held in Thessaloniki, Greece, in November 2014.

Book Description
Structural Design for Fire Safety, 2nd edition Andrew H. Buchanan, University of Canterbury, New Zealand Anthony K. Abu, University of Canterbury, New Zealand A practical and informative guide to structural fire engineering This book presents a comprehensive overview of structural fire engineering. An update on the first edition, the book describes new developments in the past ten years, including advanced calculation methods and computer programs. Further additions include: calculation methods for membrane action in floor slabs exposed to fires; a chapter on composite steel-concrete construction; and case studies of structural collapses. The book begins with an introduction to fire safety in buildings, from fire growth and development to the devastating effects of severe fires on large building structures. Methods of calculating fire severity and fire resistance are then described in detail, together with both simple and advanced methods for assessing and designing for structural fire safety in buildings constructed from structural steel, reinforced concrete, or structural timber. Structural Design for Fire Safety, 2nd edition bridges the information gap between fire safety engineers, structural engineers and building officials, and it will be useful for many others including architects, code writers, building designers, and firefighters. Key features: • Updated references to current research, as well as new end-of-chapter questions and worked examples. •Authors experienced in teaching, researching, and applying structural fire engineering in real buildings. • A focus on basic principles rather than specific building code requirements, for an international audience. An essential guide for structural engineers who wish to improve their understanding of buildings exposed to severe fires and an ideal textbook for introductory or advanced courses in structural fire engineering.
