In the last few decades economic losses due to natural disasters have increased exponentially worldwide and little progress has been seen in reducing their rate of fatalities. This also holds for earthquake disasters and is mainly due to increasing population and industrial density in high hazard and vulnerability areas. Although the prediction of earthquakes is not yet practicable, current technology allows prompt identification of the onset of any dangerous seismic event. Hence early warning and rapid disaster information systems are becoming important means for strengthening prevention and social resilience against the adverse effects of major natural events and should therefore become the keystones of disaster mitigation.
The term early warning is now widely used with various meanings in scientific, economic and sociological communities. Even in the scientific world the term is used in slightly different ways although there is a growing consensus in defining early warning as all the action that can be taken during the lead time of a catastrophic event. The lead time is defined as the time elapsing between the moment when the occurrence of a catastrophic event in a given place is reasonably certain and the moment it actually occurs. Typical lead times are of the orders of seconds to tens of seconds for earthquakes, minutes to hours for tsunamis, and hours to days for landslides, floods and volcanic eruptions. In more general terms, early warning is the provision of timely and effective information, through identified institutions, allowing individuals
exposed to a hazard to take action in order to avoid or reduce their risk and prepare for effective response. Although the definition of lead time for non-seismic hazards may be
ambiguous (the term “reasonably certain” may need a more precise probabilistic definition), for earthquakes the definition is unequivocal as the lead time will start when the first waves are released by the earthquake source. Indeed, the physical basis for earthquake early warning is simple: strong ground shaking is caused by shear-waves and by the subsequent surface waves which travel at about half the speed of the primary waves and much slower than electromagnetic signals transmitted wireless and/or by cable.

Dear Admin.
when I want to create a mirror link, then to make a good post I have to open post generator, typing on the appropriate box, hit the generate button copy and the paste the link.
I suggest you to create a small button in reply box like when I want to create a private note so I don't have to open post generator to create a good post in mirror.
Recently i entered the forum and got a question regarding new rules (that you should post requests in the correct section and not on the same request page). Anyway, i incidentally clicked on "decline" (my mistake) but quickly a realized and clicked over "agree". Then i got a page saying you have agreed and now be taken back to forum. Later a realized some of my point were deleted (status went from semi pro-engineer to engineer). Did my lost of points had to do anything with this?

Design of Plated Structures: Eurocode 3: Design of Steel Structures, Part 1-5
The main aim of this book is to provide practical advice to designers of plated structures for correct and efficient application of EN 1993-1-5 design rules. In chapter 1 the purpose, the scope and the structure of the book is explained. In chapter 2 a rather detailed and commented overview of EN 1993-1-5 design rules is given following the structure of the standard. Shear lag effect as well as plate buckling problems due to direct stresses, shear forces, transverse forces and interactions of these effects are covered. This chapter also includes a reduced stress method and a finite element analysis approach to plate buckling problems. A large number of design examples illustrate the proper application of individual design rules. Chapter 3 and 4 bring two complete design examples on a crane runway and a box-girder bridge.

The book reflects the current situation in precast concrete construction. Besides general observations regarding building with precast concrete elements, the book focuses first and foremost on the boundary conditions for the design of precast concrete structures, loadbearing elements and façades. Connections and specific structural and constructional issues are covered in detail and stability of precast concrete structures is another central theme. The requirements brought about by the emergence of the European Single Market are explained and the diverse possibilities for façade design are presented. A chapter on the production processes provides the reader with an indispensable insight into the characteristics of this form of industrialised building.
The book is a practical tool for engineers, but certainly also architects and students.
One of the authors' intentions is to demonstrate to engineers and architects the possibilities that factory prefabrication can offer, and hence pave the way towards the economic application and ongoing development of precast concrete construction.
