Seismic Design of Industrial Facilities demands a deep knowledge on the seismic behaviour of the individual structural and non-structural components of the facility, possible interactions and last but not least the individual hazard potential of primary and secondary damages. From 26.-27. September 2013 the International Conference on Seismic Design of Industrial Facilities firstly addresses this broad field of work and research in one specialized conference. It brings together academics, researchers and professional engineers in order to discuss the challenges of seismic design for new and existing industrial facilities and to compile innovative current research. This volume contains 50 contributions to the SeDIF-Conference covering the following topics with respect to the specific conditions of plant design: · International building codes and guidelines on the seismic design of industrial facilities · Seismic design of non-structural components · Seismic design of silos and liquid-filled tanks - Soil-structure-interaction effects · Seismic safety evaluation, uncertainties and reliability analysis · Innovative seismic protection systems · Retrofitting The SeDIF-Conference is hosted by the Chair of Structural Statics and Dynamics of RWTH Aachen University, Germany, in cooperation with the Institute for Earthquake Engineering of the Dalian University of Technology, China.

"This report offers practical recommendations regarding the design and safety of new and existing petrochemical facilities during and following an earthquake"--

In the first part of this thesis, a risk-targeted decision model for the verification of the seismic performance of a single industrial unit is presented. It includes the assessment of the seismic demand for a design earthquake and the seismic capacity, which is reduced by a risk-targeted safety factor. Such a safety factor implicitly guarantees the desired performance of the unit with a predefined target (acceptable) risk. The proposed risk-targeted decision model is similar to the code-based approach, which is familiar to engineers. However, it does not solve the issue of the definition of target risk for the units of an industrial facility. For this reason, the seismic design parameters for the units of an industrial facility should be evaluated for a tolerable risk considering the entire industrialised urban area, as introduced in the second part of the thesis. The proposed methodology comprises five processes: (1) fatality analysis with consideration of domino effects (e.g. fires, explosions, toxic dispersions); (2) population analysis to simulate the spatial and temporal variability of the distribution of people in the area; (3) seismic hazard analysis for the location; (4) definition of the tolerable risk in terms of the annual number of fatalities and (5) iterative adjustment of target fragility function of the industrial units. The last process comprises the disaggregation of the fatality risk, which provides useful information about the most critical units. The capability of the new framework for the risk-targeted design of units of an industrial facility is demonstrated by means of examples. It is shown that the domino effects can have a significant impact on the fatality risk. Moreover, the target seismic fragility functions of industrial units can vary significantly if the performance objective is defined by the fatality risk of the entire industrialised urban area.

Topics include design and evaluation philosophy, seismic hazards such as ground shaking, fault rupture, and tsunamis, analysis and load definition, primary structural design criteria and considerations, walkdown evaluations of existing facilities, design and evaluation of tanks at grade, and retrofit design and procedures for seismically deficit structures.

Despite significant development in earthquake analysis and design in the last 50 years or more, different structures related to industry, infra structure and human habitats get destroyed with monotonic regularity under strong motion earthquake. Even the recent earthquake in Mexico in September 2017 killed a number of people and destroyed national assets amounting to hundreds of millions of dollars. Careful evaluation of the technology reveals that, despite significant development in earthquake engineering, most of the books that are available on the market for reference are primarily focused towards buildings and framed type structures. It is accepted that during an earthquake it is buildings that get destroyed most and has been the biggest killers of human life. Yet, there are a number of structures like retaining walls, water tanks, Bunkers, silos, tall chimneys, bridge piers etc that are equally susceptible to earthquake, and if damaged can cause serious trouble and great economic distress. Unfortunately, many of these systems are analyzed by techniques that are too simplified, unrealistic/obsolete or nothing is done about them, ignoring completely the seismic effects, as no guidelines exist for their analysis/design (like seismic analysis of counterfort retaining walls or dynamic pressures on bunker walls etc.). This highly informative book addresses many of these items for which there exists a significant gap in technology and yet remain an important life line of considerable commercial significance.The book is an outcome of authors' academic research and practice across the four continents (USA, Europe, Africa and Asia) in the last thirty two years, where many of these technologies have been put in practice, that got tested against real time earthquakes. All methods presented herein have been published previously in peer reviewed research journals and international conferences of repute before being put to practice. Professionals working in international EPC and consulting engineering firms, graduates taking advanced courses in earthquake engineering, doctoral scholars pursuing research in earthquake engineering in the area of dynamic soil structure interaction (DSSI) and advanced under graduates wanting to self-learn and update themselves on earthquake analysis and design are greatly benefited from this book.
