Structural Analysis And Design To Prevent Disproportionate Collapse

"This book features a detailed introduction to progressive collapse and the use of FE programs such as ABAQUS in modeling. Case studies based on various types of structures such as multi-story buildings, long-span space structures, and bridges demonstrate failure mechanisms and effective mitigation methods in practice"--

Hard Guidance on Preventing Disproportionate CollapseDisproportionate collapse is a pressing issue in current design practice.

Structural Design of Buildings: Holistic Design is the essential reference for structural engineers involved in the design of buildings and other structures. It forms part of the Structural Design of Buildings series and introduces the concepts and principles involved in holistic structural design of a building.

The interest of Structural engineers is increasing to prevent the progressive collapse of the building. After the collapse of World Trade Center (WTC) Tower many government and private authorities worked on developing design guidelines for progressive collapse resistant structures. Among all the guidelines the U.S. General Service Administration (GSA) and Department of Defense (DoD) is most widely used by structural engineers. Historical background, mechanism, causes and types of progressive collapse is discussed in this book. This book also represents progressive collapse analysis of 4-storey and 10-storey Asymmetrical reinforced concrete (RC) building considering GSA and DoD guidelines. Linear static and dynamic as well as nonlinear static and dynamic analysis is carried out using Alternate Path Method (APM). APM is threat independent method in which critical columns from ground floor and intermediate floor are removed and demand-capacity ratio (DCR) is found out for beams and columns. From the values of DCR potential for progressive collapse is analysed. Different alternatives are explored to mitigate the potential of progressive collapse of buildings.

A book on Recent Developments in Civil engineering would likely focus on the latest advancements and innovations in the field of Civil Engineering. The book would cover a wide range of topics related to Civil engineering, such as sustainable infrastructure design, construction materials and construction techniques, transportation systems and infrastructure, geotechnical engineering, water resources and management, environmental engineering and sustainability of structures and its design.

The design of tall buildings and complex structures involves challenging activities, including: scheme design, modelling, structural analysis and detailed design. This book provides structural designers with a systematic approach to anticipate and solve issues for tall buildings and complex structures. This book begins with a clear and rigorous exposition of theories behind designing tall buildings. After this is an explanation of basic issues encountered in the design process. This is followed by chapters concerning the design and analysis of tall building with different lateral stability systems, such as MRF, shear wall, core, outrigger, bracing, tube system, diagrid system and mega frame. The final three chapters explain the design principles and analysis methods for complex and special structures. With this book, researchers and designers will find a valuable reference on topics such as tall building systems, structure with complex geometry, Tensegrity structures, membrane structures and offshore structures. Numerous worked-through examples of existing prestigious projects around the world (such as Jeddah Tower, Shanghai Tower, and Petronas Tower etc.) are provided to assist the reader’s understanding of the topic Provides the latest modelling methods in design such as BIM and Parametric Modelling technique Detailed explanations of widely used programs in current design practice, such as SAP2000, ETABS, ANSYS, and Rhino Modelling case studies for all types of tall buildings and complex structures, such as: Buttressed Core system, diagrid system, Tube system, Tensile structures and offshore structures etc.

The successful design and construction of iconic new buildings relies on a range of advanced technologies, in particular on advanced modelling techniques. In response to the increasingly complex buildings demanded by clients and architects, structural engineers have developed a range of sophisticated modelling software to carry out the necessary structural analysis and design work. Advanced Modelling Techniques in Structural Design introduces numerical analysis methods to both students and design practitioners. It illustrates the modelling techniques used to solve structural design problems, covering most of the issues that an engineer might face, including lateral stability design of tall buildings; earthquake; progressive collapse; fire, blast and vibration analysis; non-linear geometric analysis and buckling analysis . Resolution of these design problems are demonstrated using a range of prestigious projects around the world, including the Buji Khalifa; Willis Towers; Taipei 101; the Gherkin; Millennium Bridge; Millau viaduct and the Forth Bridge, illustrating the practical steps required to begin a modelling exercise and showing how to select appropriate software tools to address specific design problems.
