Available in PDF, EPUB and Kindle. Book excerpt: This book provides a general introduction to the topic of buildings for resistance to the effects of abnormal loadings. The structural design requirements for nuclear facilities are very unique. In no other structural system are extreme loads such as tornadoes, missile and loud interaction, earthquake effects typical in excess of any recorded historical data at a site, and postulated system accident at very low probability range explicitly, considered in design. It covers the whole spectrum of extreme load which has to be considered in the structural design of nuclear facilities and reactor buildings, the safety criteria, the structural design, the analysis of containment. Test case studies are given in a comprehensive treatment. Each major section contains a full explanation which allows the book to be used by students and practicing engineers, particularly those facing formidable task of having to design complicated building structures with unusual boundary conditions.

Available in PDF, EPUB and Kindle. Book excerpt: Despite all the efforts being put into expanding renewable energy sources, large-scale power stations will be essential as part of a reliable energy supply strategy for a longer period. Given that they are low on CO2 emissions, many countries are moving into or expanding nuclear energy to cover their baseload supply. Building structures required for nuclear plants whose protective function means they are classified as safety-related, have to meet particular construction requirements more stringent than those involved in conventional construction. This book gives a comprehensive overview from approval aspects given by nuclear and construction law, with special attention to the interface between plant and construction engineering, to a building structure classification. All life cycle phases are considered, with the primary focus on execution. Accidental actions on structures, the safety concept and design and fastening systems are exposed to a particular treatment. Selected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "Beton-Kalender" has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "ferro-concrete" structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "tempestuous development" in this form of construction came to an end. However, the "Beton-Kalender" quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since.
Download or read book Advanced Modeling and Evaluation of the Response of Base Isolated Nuclear Facility Structures to Vertical Earthquake Excitation written by Eric Scott Keldrauk and published by . This book was released on 2012 with total page 742 pages. Available in PDF, EPUB and Kindle. Book excerpt: The commissioning and construction of new nuclear power plants in the United States has dwindled over the past 30 years despite significant innovation in reactor technology. This is partially due to the ever-increasing seismic hazard estimates, which increases the demand on and risk to nuclear power plant structures. Seismic base isolation is a mature technology which introduces a laterally-flexible and vertically-stiff layer between the foundation and superstructure to significantly reduce the seismic response of the structure, systems, and components therein. Such devices have also been noted to concentrate the displacement response in one plane, reduce higher-mode participation, and provide damping to protect against excessive displacements, all of which aid in increasing safety margins for seismically-isolated nuclear structures. Despite numerous studies analyzing the applicability of seismic base isolation to nuclear power plant structures, some of which are discussed herein, no seismically-isolated nuclear plant has been constructed in the United States. This study presents a time-domain procedure for analyzing the performance of seismically-isolated nuclear structures in response to design-basis earthquake events using ALE3D. The simulations serve as a parametric study to assess the effects of soil column type, seismic isolation model, superstructure mesh, and ground motion selection on global displacements, rotations, and accelerations, as well as internal floor accelerations. Explicit modeling of the soil columns and superstructures enables detailed analysis of soil-structure interaction. The soil columns analyzed have constant properties over the height of the finite element soil mesh and include rock, soft rock, and stiff soil sites, as well as a "no soil" case for comparison. Four separate 3-dimensional seismic isolation bearing models were coded into ALE3D and validated. These include models for friction pendulum, triple friction pendulum, simplified lead rubber, and robust lead rubber bearings. Lastly, two superstructure finite element meshes were considered: a cylindrical plant design meant to represent a typical conceptual design for advanced reactors, and a rectangular plant design meant to represent an advanced boiling water reactor. The ground motions considered include 30 three-component time history records scaled to meet the seismic hazard for the Diablo Canyon nuclear plant. Every combination of soil column, isolator model, and superstructure were subjected to a subset of three of the harshest ground motions, termed the "basic motions", and the combinations which included the rectangular plant design atop the rock soil column were subjected to all 30 motions. The results of the various simulations including accelerations in the soil columns and superstructures as well as displacements and rotations in the isolators and superstructures are presented. The results suggest three possible effects: an isolator-type effect, a soil-type effect, and a slenderness effect. The isolator-type effect refers to significant increases in vertical soil acceleration amplifications, isolator uplift/tension, and global rotations including torsion and overturning for friction bearings in comparison to elastomeric bearings. Additionally it is noted that inclusion of lead plug softening has the effect of increasing peak lateral isolator deformations, especially for the ground motions that naturally induce high-amplitude deformations in the bearings. These results suggest that uplift/tension may be troublesome in high-seismic areas and the use of restrainers should be analyzed as a possible solution. Furthermore, these results reinforce the lateral design displacement estimate procedures for seismically-isolated nuclear structures in ASCE4-11. The results prove that explicit inclusion of the soil column is necessary for proper response characterization and the chosen soil properties greatly affect the efficacy of seismic isolation designs. The soil-type effect comes from observations of comparative simulations which show that, in general, peak isolator uplift/tension and deformation, as well as peak global displacements and rotations including torsion and overturning increase as the soil column becomes less-stiff, regardless of the isolator model or superstructure considered. These results suggest that although seismic isolation can be effective for structures atop a variety of soil columns, it is imperative that a single isolator design only be considered applicable to a corresponding soil column unless extensive analyses prove otherwise for a specific case. Differences in peak response parameters between the two superstructures point to a possible slenderness effect. Specifically, the isolator deformations as well as the global displacements and rotations are observed to increase for the cylindrical superstructure in comparison to the rectangular superstructure cases utilizing the same ground motion, soil column, and isolator model. Should further research reaffirm this effect, a practical limit could be set for superstructure slenderness.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In complying with direction from the U.S. Department of Energy (DOE), Richland Operations Office (RL) (07-KBC-0055, 'Direction Associated with Implementation of DOE-STD-1189 for the Sludge Treatment Project, ' and 08-SED-0063, 'RL Action on the Safety Design Strategy (SDS) for Obtaining Additional Solid Waste Processing Capabilities (M-91 Project) and Use of Draft DOE-STD-I 189-YR'), it has been determined that the seismic design requirements currently in the Project Hanford Management Contract (PHMC) will be modified by DOE-STD-1189, Integration of Safety into the Design Process (March 2007 draft), for these two key PHMC projects. Seismic design requirements for other PHMC facilities and projects will remain unchanged. Considering the current early Critical Decision (CD) phases of both the Sludge Treatment Project (STP) and the Solid Waste Processing Facilities (M-91) Project and a strong intent to avoid potentially costly re-work of both engineering and nuclear safety analyses, this document describes how Fluor Hanford, Inc. (FH) will maintain compliance with the PHMC by considering both the current seismic standards referenced by DOE 0 420.1 B, Facility Safety, and draft DOE-STD-1189 (i.e., ASCE/SEI 43-05, Seismic Design Criteria for Structures, Systems, and Components in Nuclear Facilities, and ANSI!ANS 2.26-2004, Categorization of Nuclear Facility Structures, Systems and Components for Seismic Design, as modified by draft DOE-STD-1189) to choose the criteria that will result in the most conservative seismic design categorization and engineering design. Following the process described in this document will result in a conservative seismic design categorization and design products. This approach is expected to resolve discrepancies between the existing and new requirements and reduce the risk that project designs and analyses will require revision when the draft DOE-STD-1189 is finalized.
