How to Design Seismic-Resistant Buildings in Reinforced Concrete: A Guide by Ghersi and Lenza
Reinforced concrete is one of the most widely used materials for building structures in seismic areas. However, designing safe and efficient buildings in reinforced concrete requires a thorough knowledge of the seismic behaviour of this material, as well as of the relevant codes and standards. In this article, we will introduce you to a comprehensive book that covers all the aspects of seismic design of reinforced concrete buildings: ghersi lenza edifici antisismici in cemento armato pdf download.
The book, written by Aurelio Ghersi and Pietro Lenza, two renowned experts in the field of structural engineering, is titled \"Edifici antisismici in cemento armato\" (Seismic-resistant buildings in reinforced concrete). It was published in 2009 by Dario Flaccovio Editore, and it comes with a CD-ROM that contains software tools and examples for practical applications. The book is divided into four parts:
The first part provides an overview of the basic concepts of seismic engineering, such as earthquake characteristics, ground motion, response spectra, ductility, energy dissipation, and performance-based design.
The second part focuses on the analysis of reinforced concrete structures under seismic actions, including linear and nonlinear methods, modal analysis, pushover analysis, capacity design, and seismic detailing.
The third part deals with the design of new building structures for earthquake resistance, covering different types of structural systems, such as frames, walls, dual systems, infills, base isolation, and energy dissipation devices.
The fourth part addresses the seismic assessment and retrofitting of existing structures, presenting the main criteria and techniques for evaluating the seismic vulnerability and upgrading the seismic capacity of reinforced concrete buildings.
The book is written in a clear and rigorous style, with a wealth of figures, tables, formulas, and references. It is aimed at students, researchers, and practitioners who want to deepen their knowledge and skills in the field of seismic design of reinforced concrete structures. The book is also suitable for preparing for professional exams and certifications in seismic engineering.

Reinforced concrete is a composite material that consists of concrete and steel reinforcement bars. The concrete provides resistance to compression, while the steel provides resistance to tension. The combination of these two materials results in a strong and durable material that can withstand various types of loads and environmental conditions.
However, reinforced concrete is not immune to the effects of earthquakes, which can cause severe damage and collapse of buildings. Earthquakes generate horizontal and vertical forces that induce cyclic deformations and stresses in the structures. These forces can exceed the elastic limit of the materials, causing cracking, yielding, buckling, and failure. Therefore, it is essential to design reinforced concrete structures that can resist seismic actions without losing their functionality and safety.
Seismic design of reinforced concrete structures is based on the concept of ductility, which is the ability of a structure to undergo large deformations without losing its strength. Ductility allows the structure to dissipate the seismic energy through plastic deformations, reducing the demand on the elastic elements. To achieve ductility, reinforced concrete structures must be properly detailed and reinforced, following the principles of capacity design and strong column-weak beam hierarchy.
Capacity design is a method that ensures that the plastic deformations are concentrated in predefined regions of the structure, called plastic hinges, while the rest of the structure remains elastic. This way, the structure can form a stable mechanism that can accommodate large displacements without collapsing. Strong column-weak beam hierarchy is a criterion that ensures that the columns are stronger than the beams, so that the plastic hinges form at the ends of the beams rather than at the ends of the columns. This way, the columns can maintain their axial load capacity and prevent global instability. a474f39169
