Structural Dynamics in Earthquake and Blast Resistant Design

Structural Dynamics in Earthquake and Blast Resistant Design is a book that bridges the gap between theory and practical design in earthquake and blast resistant engineering. It introduces equations of motion, free and forced vibrations, and support motion, and explains responses of multistorey buildings subjected to earthquake ground motion. It also highlights problems encountered in such designs while following relevant codes of practice. Examples of inelastic hysteretic systems and inelastic torsional response of structures are provided, and research output of retrofitting techniques is mentioned. A new approach of creating a fictitious boundary to obtain blast loads on below-ground structures is presented. The book is aimed at senior undergraduates and graduates in civil engineering, earthquake engineering, and structural engineering.

Structural Dynamics in Earthquake and Blast Resistant Design is a comprehensive guide that delves into the fundamental aspects of structural dynamics essential for designing earthquake-resistant structures. By combining theoretical principles with practical design elements, the book aims to bridge the gap between theory and practice, making it more accessible and valuable to structural engineers.

The book begins by introducing the equations of motion and free and forced vibrations of SDF and MDF systems, along with the principles of D'Alembert, Duhamel's integral, relevant impulse, pulse, and sinusoidal inputs. It also covers support motion and triangular pulse input, which are crucial for earthquake and blast resistant designs, respectively.

The book further explores the responses of multistorey buildings subjected to earthquake ground motion through a well-known mode superposition technique. Examples of real-size structures designed and constructed using popular software such as ETABS and STAAD are provided, showcasing the practical application of structural dynamics principles.

However, designing earthquake-resistant structures is not without its challenges. The book highlights the problems encountered in such designs while adhering to relevant codes of practice like IS 1893 2016 due to architectural constraints. One particularly difficult constraint is avoiding torsional modes in fundamental and first three modes, as well as the inability to achieve sufficient mass participation. In the case of blast resistant design, the challenge lies in modeling the blast effects on basement storeys, particularly in obtaining the attenuation due to the soil.

The book provides detailed examples of inelastic hysteretic systems, where the top soft storey plays a significant role in expending the input energy, provided it is not below a stiffer storey. It also illustrates the inelastic torsional response of structures asymmetric in plan, emphasizing the concept of ductility and its importance in designing earthquake-resistant structures.

Throughout the book, the results of research and case studies are presented, providing valuable insights into the performance of earthquake-resistant structures. The book is well-organized, with clear explanations and illustrations that make it accessible to students, professionals, and researchers in the field of structural dynamics and earthquake engineering.

In conclusion, Structural Dynamics in Earthquake and Blast Resistant Design is a valuable resource for structural engineers seeking to enhance their understanding of structural dynamics and design earthquake-resistant structures. By blending theory with practical design elements, the book provides a comprehensive guide that bridges the gap between theory and practice, making it an essential tool for anyone involved in this field.
