In the Republic of Serbia, as well as in other countries in the region, the use of Eurocodes for the design of all types of buildings, including reinforced concrete (RC) structures, has recently become mandatory. Eurocode 8 (Part 1) (EC8-1) contains requirements for the seismic design of building structures, including seismic analysis methods, as well as design requirements for structural elements of RC, steel, masonry, and timber buildings.
Although the current generation of Eurocodes was developed over 20 years ago, there are no official commentaries explaining the theoretical approach and the basis for certain provisions of these regulations. Therefore, technical literature explaining the Eurocode requirements and their application, such as textbooks and manuals, is of exceptional importance, primarily for numerous structural engineers who during their studies learned the former Yugoslav technical regulations for structural design and have applied them in practice over the last 30 years.
The latest book by Prof. Dr. Srđan Janković, dedicated to the seismic design of RC building structures in accordance with EC8-1, is of particular significance for most structural engineers, since building design is the most common activity in construction practice.
This book is divided into 8 chapters and contains over 650 pages. The first three chapters, which cover about one-third of the book, present the fundamentals of structural dynamics, principles of seismic design, and methods for seismic analysis of structures. The content of these chapters is very important for competent seismic design, as the designer is expected to have satisfactory knowledge of structural dynamics, primarily related to the response of structures to the dynamic effects of earthquakes. The second chapter introduces the reader to the basic requirements of EC8-1 and presents the types of reinforced concrete structural systems, seismic action, as well as requirements related to the expected behavior of structures according to this standard. The third chapter presents traditional seismic analysis methods used in accordance with EC8-1, such as the lateral force method and modal response spectrum analysis (multimodal analysis). In addition, the author provides a detailed description of the concept and methodology of nonlinear static (pushover) analysis, which is increasingly applied in seismic design of structures. The same chapter also presents the theoretical approach to probabilistic assessment of seismic safety of structures, which is used in very current seismic risk assessment studies.
The fourth chapter of the book introduces reinforced concrete (RC) structures and deals with the characteristics of concrete and steel as constitutive materials relevant to seismic design according to EC8-1, such as the influence of concrete confinement by transverse reinforcement, steel grades and corresponding yield strength values, tensile strength, etc. The fifth chapter is the most extensive and covers seismic design of RC frames, the most complex of all systems for resisting seismic actions. Different failure mechanisms of these systems are thoroughly explained, as well as the design principles of the main structural elements of frames, such as columns, beams, and joints. The important topic of determining the characteristics of plastic hinges (moment-curvature) in cross-sections of RC frame elements is also addressed. It is very significant that the book explains not only the behavior and design of these elements under seismic effects, but also the requirements related to reinforcement detailing. This chapter presents the EC8-1 requirements regarding the design of RC frames of different ductility classes (from low to high), as well as detailed calculation examples of typical RC frames for two different ductility classes. The topic of RC frames with infill is also covered in this chapter, including relevant EC8-1 requirements, but unfortunately, no numerical example is included.
The sixth chapter deals in detail with the seismic design of reinforced concrete (RC) shear walls, a structural system often used for resisting seismic forces in tall buildings. The chapter explains the approach for calculating the distribution of seismic effects in buildings with shear walls, as well as the behavior mechanism of walls under bending moments and shear forces caused by earthquakes. The EC8-1 requirements related to the design of walls of various ductility classes are presented. Principles for designing different types of walls are covered, including ductile slender walls as well as low walls. Special attention is given to the design of coupled walls, as well as the explanation of behavior and design requirements for coupling beams, which are critical elements of such walls. Detailed calculation examples of slender walls of medium and high ductility classes, as well as coupled walls, are presented. This chapter also covers the topic of dual systems (combination of RC walls and frames), but no calculation example is included.
The seventh chapter addresses the seismic design of interstory structures (floors/ceilings), which play a critical role in resisting horizontal seismic forces and transferring those forces to vertical structural elements (frames and walls). The EC8-1 requirements related to the design of these elements are presented, along with calculation examples. The eighth chapter deals with the design of foundation structures to resist seismic actions according to EC8-1. Relevant topics concerning seismic design of foundations and foundation beams are covered, as well as the advanced topic of soil-structure interaction. The design of foundation beams is illustrated through a calculation example.
The author of the book is Prof. dr Srđan Janković, a full professor at the University of Montenegro. Prof. Janković has been employed at the Faculty of Civil Engineering in Podgorica since 1994. His extensive experience in educating civil engineering and architecture students, as well as in engineering practice, has significantly contributed to the quality of this book. This valuable experience is especially evident in the introductory discussions and comments related to the topics of individual chapters, as well as in the detailed calculation examples, which are particularly useful for students and readers encountering this complex standard for the first time.
This book represents a significant contribution to raising the level of knowledge and education of current and future structural engineers, and it deserves a place on the bookshelf alongside international authors such as Park, Paulay, Priestley, Penelis, Fardis, and Moehle. A special value of the book is that, for the first time, this complex professional subject is presented in a language that is understandable in the Republic of Serbia and neighboring countries in the region.
The book was published at the beginning of 2022 in Podgorica, and it is available in the Republic of Serbia through AGM Knjige.
