Preface of Earthquake Resistant Buildings from Reinforced Concrete PDF

The civilization progress of a time-period and a country was always historically presented by the level of its constructions. This happens because the culture, the architecture, the mechanics and the technology either as a condition or as the result of people’s cultural level are reflected upon the various constructions.

 In every region, the architectural forms were influenced by the environmental conditions present, sun or clouds, hot or cold, mountain or sea, rock or mud. At the same time, the intensity of the earthquakes played a catalytic role in the various civilizations which usually became extinct after a severe seismic event. People, due to the awe and their sense of weakness, always had and still have the tendency to forget such tragic events.

Nowadays, the dissemination of science and the advancements in the material science and technology as well as in the computing and software technology, enable us to face earthquakes with prudence but without fear. We have to modify our architecture in order to enhance the earthquake resistant capacity of the constructions the same way we have modified it in favour of the energy saving.

The new architectural form will predominate after it has proven that not only can it be materialized but also that it can sustain severe earthquakes. The antiseismic science and technology has made great steps during the last three decades. This has led to design and constructional rules which have been established as regulations, like the recent Eurocode 8.

The engineers, mainly because of their scientific background, have accepted these design rules and they apply them with no hesitation. On the other hand, the new constructional rules as well as the new practices have not yet been adopted by the rest of the construction’s materialization bodies. This book refers to the constructional issue of the reinforced concrete, earthquake resistant buildings. The way of antiseismic construction, the materialization details, the required quantities of materials and labors are presented in the detailing of the structural frame.

The detailing regards everyone involved in a building’s erection, the architect, the civil engineer, the supervisor engineer, the contractor, the foreman and the technician. In order to compose or to comprehend the detailing, the technician must have a thorough knowledge of the construction. The only way to learn such a complex subject as the reinforced concrete and such a critical subject like the antiseismic construction, first and foremost, one must learn to love them. In this book, the combination of knowledge and love is referred to as ‘art’.

This ‘art’ of the earthquake resistant construction is our intention to disseminate. The realization of this book was possible thanks to the detailed knowledge and devotion of two good friends and colleagues, the civil engineer Giannis Lirakis and the Architect Engineer Costas Anastasiadis.

The latter, with the use of various software programs, modeled and designed in numerous ways the examples included in this book. I would like to thank all my collaborators engineers, technologists, contractors and technicians for their valuable help in the various issues and whom with particular gratitude I cite in the page of bibliography.
