(London), in Earthquake-Resistant Structures, 2013 6.5.1 Tsunami Risk Maps An Important Step: Using new USGS seismic risk maps based on 2008 data ( Caltrans 1971 ), the NRC in August 2010 published new estimates of risk at nuclear power reactors in eastern and central states. Besides the proximity, severity, and frequency of earthquakes, the new estimates take into account design standards used at each plant along with the type of rock or soil on which the plant is built. http://sewonfd.com/userData/board/brother-mfc-8460n-manual.xml


Geologists and seismologists, remembering what they learned about rocks, are steadily raising their estimates of the risk of severe quakes based on these new maps. New faults are found, and new computer models change predictions for how the ground shakes. Of special note, according to the USGS, is an allowance for large waves in the New Madrid, Missouri, fault area, roughly centered on the state’s Bootheel, as well as inclusion of offshore faults near Charleston, South Carolina, and new data from the mountains of east Tennessee. With each new map, the areas of only negligible risks have grown smaller. Interestingly, the reactor with the highest risk rating is 24 miles north of New York City, in the village of Buchanan, New York, at the Indian Point Energy Center, which generates up to one-third of the electricity for New York City. There, on the east bank of the Hudson, Indian Point nuclear reactor 3 has the highest risk of earthquake damage in the country, according to new NRC risk estimates. Indian Point 2 does not rate as risky, with 1 chance in 30,303 each year. A ranking of the 104 U.S. nuclear reactors was prepared by the NRC based on estimates of risk of catastrophic failure caused by earthquakes. The chance of serious damage from a quake ranges from Indian Point (1 chance in 10,000 each year) to the Callaway nuclear plant in Fulton, Missouri, which the NRC ranked as the least risky (1 chance in 500,000 each year). Installations in Massachusetts and Pennsylvania rank second and third, respectively, followed by those in Tennessee, another plant in Pennsylvania, then plants in Florida, Virginia, and South Carolina. At sixth and seventh riskiest are, respectively, California’s Diablo Canyon and Pennsylvania’s Three Mile Island. The risk calculations take into consideration two main factors: the chance of a serious quake, and the design of a plant. https://ayurvedia.ch/3k-engine-manual


Surprisingly, nuclear plants built in earthquake zones, such as the California coastline, have a lower risk of damage since they were built in anticipation of a major quake and sufficient safeguards were provided. Power plants in the East, South, and Midwest, where seismic design standards are considered lower, now find themselves at the top of the NRC’s danger list because of upgraded acceleration coefficients and seismic zone reevaluation.

(London), in Earthquake-Resistant Structures, 2013 Displacement Design A substantial design shift occurred with the California Department of Transportation’s ( Caltrans ’) adoption of displacement design methods (as Memo to Designers 20-11) outlined in a report issued by the University of California, San Diego. Caltrans’ seismic design criteria (SDC) incorporated these methods in an innovative seismic performance approach. In the SDC design philosophy there is a shift from a “force-based assessment” of seismic demand to a “displacement-based assessment” of demand and capacity. This newly adopted approach is based on comparing the elastic displacement demand to the inelastic displacement capacity of the primary structural components of a bridge, while ensuring a minimum level of inelastic capacity at all potential plastic hinge locations. Displacement ductility methods were used initially for the retrofit of the Santa Monica Viaduct on Route 10 in Los Angeles, which was being retrofitted as part of the Caltrans Seismic Retrofit Program. Displacement design methods were incorporated into other seismic retrofit projects and ultimately became the de facto seismic retrofit design methodology. Seismic design requirements may include data on ground stabilization underneath the structure since heavily shaken ground breakup may lead to collapse. These data are obtained with shake tables and kinematic building models. https://www.accessoriperdisabili.com/images/bricklaying-technical-manual.pdf


(In general, a building model is said to have similarity with the real object if the two share geometric similarity, kinematic similarity, and dynamic similarity; this concept is explained in Chapter 5.) Currently the most advanced shake table is the Japanese E-Defense Shake Table.

(London), in Earthquake-Resistant Structures, 2013 4.2.1 California Seismology The Pacific Plate extends from western California to Japan and includes much of the Pacific Ocean floor. The North American Plate comprises most of the North American continent and parts of the Atlantic Ocean. The Pacific Plate is grinding northwestward past the North American Plate along the San Andreas Fault (at a rate of about two inches per year). Thus, Southwestern California is moving horizontally northward toward Alaska. The dividing point, or margin, between the two is the San Andreas Fault system, which extends from the Salton Sea in the south to Cape Mendocino in the north—an 800-mile stretch almost the entire length of California. It was San Andreas that caused the 1906 San Francisco earthquake (magnitude 7.8), which killed more than 3,000 people and destroyed much of the city ( Figure 4.3 illustrates how this earthquake would have been measured). The Polaris Fault, named after a former mining town that sits above it, is a fraction of the size of the San Andreas Fault, at 22 miles long. Because it is located near the Martis Creek Dam at Truckee, however, it poses a major threat of an earthquake bursting the dam and potentially flooding a plain that stretches 35 miles to Reno, Nevada, a city of some 222,000 people. Unlike Japan, California faces a low risk of tsunamis from its quakes. However, the state’s real problem is the condition of its structures, many of which are of substandard construction. https://www.marthatrotts.ca/wp-content/plugins/formcraft/file-upload/server/content/files/162872c9b77fd8---caffe-charisma-manual.pdf


The Japanese are ahead of California seismic-resistant design codes have done a better job of new construction and retrofit for seismic survivability. During the 1971 San Fernando ( Figure 4.4 ), the 1989 Northridge ( Figure 4.5 ), and the 1994 Loma Prieta ( Figure 4.6 ) earthquakes in California, several concrete buildings constructed before the introduction of modern codes collapsed or were catastrophically damaged. According to a new estimate, 17,000 older concrete buildings in California could be vulnerable to seismic activity. Not all of the buildings identified are collapse hazards or prone to severe damage. However, an estimate includes a number of schools, state and local government centers, hospitals, and public safety facilities. Figure 4.4. Two examples of damage caused by the San Fernando earthquake. Figure 4.5. Northridge earthquake damage. Figure 4.6. Two examples of damage caused by the Loma Prieta earthquake. Analysis of Extent and Types of Structural Damages: A more careful study of specific buildings in order to better understand which are the riskiest, is necessary. Unlike unreinforced masonry buildings, which uniformly do not perform well in earthquakes, there is tremendous variability in older concrete buildings. Understanding what makes them vulnerable and quickly weeding out which ones, may need more detailed evaluation and possible retrofit. Caltrans Administrative and Technical Remediation Measures The California Department of Transportation ( Caltrans) has always compiled its own seismic design criteria. Caltrans developed improved reinforcement details: Closer spacing and improved detailing of column transverse reinforcement, requirements for top reinforcement in footings and pile caps, and controls on column longitudinal reinforcement splice location.

7 ABC and seismic issues “Rapid insertion” bridge replacement is being practiced. Successful ABC requires detailed planning. At the annual Transportation Research Board (TRB) meeting in January of 2007, California representatives agreed to take the lead in developing ABC techniques that addressed seismic issues. A workshop was organized by TRB, FHWA, and Caltrans and held in October 2007 in San Diego, California. Representatives from several state DOTs, FHWA, TRB, researchers, and industry met, leading to the publication of the document, “ 2007 FHWA Seismic Accelerated Bridge Construction Workshop Outcomes and Follow-up Activities.” The workshop resulted in the development of an action plan to guide future seismic ABC activities. A follow-up meeting was held at the January 2008 TRB meeting, resulting in the development of three seismic ABC-related research problem statements. In California, a Seismic ABC Work Team was created to focus efforts for application by Caltrans. The report also documents the use of precast concrete technology on several projects to reduce working days and traffic impacts. However, to fully implement ABC methods, remaining seismic issues must be resolved, particularly the development and testing of connection details capable of resisting seismic loads and deformations.

Trejo, in Handbook of Seismic Risk Analysis and Management of Civil Infrastructure Systems, 2013 Structural capacity of, and seismic demand on, an example RC bridge subject to deterioration This section gives an example of the effects of deterioration, specifically corrosion (although this could include other expansive deterioration mechanisms), on the structural capacity of and the seismic demand on a typical RC bridge. The values of the design variables listed in Table 19.1 are representative of current construction in California. {-Variable.fc_1_url-


Specifically, Mackie and Stojadinovic (2001) designed the bridge following the Caltrans Bridge Design Specification and Seismic Design Criteria ( Caltrans 1999 ). Source: Adapted from Choe et al. (2009). Three variables are assumed to be random: the compressive strength of concrete, f c.Specifically, it was assumed that f c.In addition, the mean shear capacity decays at a faster rate than the mean deformation capacity. Despite the importance of modeling complex bridge lateral boundary conditions and the existence of specific guidelines in the US ( Caltrans, ATC, MCEER) and in Europe (Eurocode 8-2) for the design of pile foundations and abutments, only minor guidance is provided by codes for numerical modeling of the entire coupled soil-bridge system. The ultimate abutment load can be assumed to be limited by a maximum static soil passive pressure of 239 kPa. The idea was to derive relationships that can be potentially used in cases where more accurate data are not available. Six typical RC Californian bridges (namely Route 14, LADWP, W180, MGR, Adobe and La Veta) and a Greek one (TY3 overpass along the Egnatia Highway) consisting of box-girder superstructures, seat-type abutments and shallow pile foundations were studied. Given the short spans and relatively high deck stiffness of the particular structures, the embankment mobilization and the inelastic behaviour of the soil material under high shear deformation levels was found to have a significant effect on the response of the bridge under seismic loading. The geometry of the TY3 case studied is illustrated in Fig. 22.2, while indicative distribution of plastic strains in the 3D space are depicted in Figs 22.3 and 22.4 for the transverse and longitudinal direction, respectively.

Unique bridge design guidelines exist for a wide variety of bridges; however, they should be verified to include concerns of the stakeholders and to comply with the jurisdictions. For large projects, the number of stakeholders and jurisdictions can be large and may have conflicting interests that must be handled carefully. Who owns the bridge now, and who will maintain it. Typically, this is a major factor in deciding which design codes and manuals will be used. The type of funding may impose some additional conditions and design considerations that must be included. For example, if the project funding includes federal funds, the bridge project may require more rigid review and oversight,while purely local funding may allow more leeway on the project design. For example, a bridge carrying heavy rail traffic over a highway will require the bridge to be designed by AREMA codes ( AREMA, 2014 ) and Railroad Grade Separation Guidelines ( BNSF Railway and Union Pacific Railway, 2007 ) but also satisfy the state design manuals for highway safety features for pier and abutments located underneath.
