  • At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacement of the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes can also trigger landslides, and occasionally volcanic activity

  • The study of earthquakes combines science, technology and expertise in infrastructure and engineering in an effort to minimize human and material losses when their occurrence is inevitable. This book is devoted to various aspects of earthquake research and analysis, from theoretical advances to practical applications. Different sections are dedicated to ground motion studies and seismic site characterization, with regard to mitigation of the risk from earthquake and ensuring the safety of the buildings under earthquake loading.

  • Recent major earthquakes around the world have shown the vulnerability of infrastructure and the need for research to better understand the nature of seismic events and their effects on structures. As a result, earthquake engineering research has been expanding as more and more data become available from a large array of seismic instruments, large scale experiments and numerical simulations.

  • Theoretical study of earthquakes as well as practical application is actually important to determine the earthquake hazard assessment and risk in a specific region. This is probably the most important contribution of seismology to society. recent earthquake showed the inadequacy of a large part of the building construction in and around the epicentral area, so the study of earthquakes has become and more important.

  • The mitigation of earthquake-related hazards represents a key role in the modern society. The mitigation of such kind of hazards spans from detailed studies on seismicity, evaluation of site effects, and seismo-induced landslides, tsunamis as well as and the design and analysis of structures to resist such actions. The study of earthquakes ties together science, technology and expertise in infrastructure and engineering in an effort to minimize human and material losses when they inevitably occur.

  • The tallness of a building is relative and can not be defined in absolute terms either in relation to height or the number of stories. But, from a structural engineer's point of view the tall building or multi-storeyed building can be defined as one that, by virtue of its height, is affected by lateral forces due to wind or earthquake or both to an extent that they play an important role in the structural design. Tall structures have fascinated mankind from the beginning of civilisation.

  • So far the scientific community agrees that the earthquake prediction is impossible. In fact, scientists can not predict the exact location, intensity and duration of an earthquake to strike a particular area. Scientists still do not know much about the details of the physical processes associated with earthquakes and their still unpredictable.

  • The mandate of the panel was to evaluate the present status of knowledge about the earthquake performance of concrete dams, including procedures for investigating the seismic safety of such structures, and to summarize its findings in a report. The report was intended specifically to inform research workers about the state of the art of earthquake analysis of concrete dams and to identify subject areas where additional knowledge is needed.

  • I knew that I would enjoy this book when I saw that Andrew Charleson had used one of my favorite buildings, the Villa Savoie in Paris, as a seismic design case study. The earthquake engineers ’ nightmare, with its pin-like pilotis, ramps and roof garden – the epitome of the free planned International Style dwelling – it floats above the field in Poissy, giving the illusion of being on the sea.
