Presentation: Overview of Hazard Assessment Results
TINCE2016 - Post-Fukushima seismic re-assessment of French Reactor Building ...Gildas POTIN
In response to the consequent events at Fukushima Daiichi Nuclear Power Plant following the 11th March 2011 Great East Japan Earthquake, the French electric utility company EDF launched a seismic re-assessment program implementation in accordance with the French Nuclear Safety Authorities. This program, called SND (S é isme Noyau Dur), aims mainly at reaching safety objectives concerning the resilience of the SSC (Structures, Systems & Components).
End of 2015 matched with the end of the first whole re-assessment of a still operating Reactor Building (RB) in France, for which innovative thinking have been necessary to optimize current methodologies and assess in detail the civil work robustness and the induced vibrations under high level of earthquake, corresponding to site SND.
Through the presentation of the keys hypotheses and methodologies used to carry out this significant study, a review based on the Tractebel and EDF knowledge of the French Reactor Buildings will propose some leads to adapt the future SND program to other Reactor Buildings.

The oxford dictionary defines an attribute as, “a quality ascribed to any person or thing”. We have extended this definition to: “seismic attributes are all the information obtained from seismic data, either by direct measurements or by logical or experience based reasoning
In reflection seismology : aseismic attributes is a quality extracted or derived from seismic data that can be analyzed in order to enhance information that might be more subtle in a traditional seismic image , leading to a better geological or geophysical interpretation of the data
Over the past decades, we have witnessed attribute developments track breakthroughs in reflector acquisition and mapping, fault identification, bright spot identification, frequency loss, thin bed tuning, seismic stratigraphy.

Civil engineering is the broadest of the engineering fields. Civil engineering focuses on the infrastructure of the world which includeWater works, Sewers, Dams, Power Plants, Transmission Towers/Lines, Railroads, Highways, Bridges, Tunnels, Irrigation Canals, River Navigation, Shipping Canals, Traffic Control, Mass Transit, Airport Runways, Terminals, Industrial Plant Buildings, Skyscrapers, etc.Among the important subdivisions of the field areconstruction engineering, irrigation engineering, transportation engineering, soils and foundation engineering, geodetic engineering, hydraulic engineering, and coastal and ocean engineering.Civil engineersbuild the world’s infrastructure. In doing so, they quietly shape the history of nations around the world. Most people can not imagine life without the many contributions of civil engineers to the public’s health, safety and standard of living. Only by exploring civil engineering’s influence in shaping the world we know today, can we creatively envision the progress of our tomorrows.

Design and Analysis of a Multistory Reinforced Concrete Frame in Different Se...ijtsrd
This study work focuses on the analysis of a structural system to determine the deformations and comparison of steel quantity of seismic zones. In this study, we have taken G 12 multi storied RC moment resisting framed structure building with the shear wall by analyzing the structure for gravity load, wind load and seismic loads for different cities. By Selecting four different cities on the basis of seismic zones zone II, zone III, zone IV, zone V and also considering that the basic wind speed. We have mainly focus on the structural system to determine the deformations and also forces induced by applied loads or ground excitation is an essential step in the design of a structure to resist earthquake. The analysis and design for all the cities are carried out using STAAD Pro' and STAAD Foundation' software which are industry standard software the world over. The wind resistant design is carried out as per IS 875 Part 3 1987 and the earthquake resistant design is carried out as per IS 1893 Part 1 2002. Analysis and design of beams, columns and shear wall have been done in STAAD Pro and the foundation is done in STAAD Foundation. We have also checked the design of some beams, columns, and footings manually and find correct. Design of RCC slabs is carried out manually for which an excel sheet is developed for working out moment coefficients for different edge conditions as per IS code. In this study work, we design and analyze a reinforced concrete frame structure in various seismic zones and we observing the variation in the behavior of the structure in various loading conditions.

Earthquake Resistance Design-Impact On Cost Of Reinforced Concrete BuilidingsIJMER
Earthquakes strike suddenly, violently and without warning at any time of the day or night.It
is highly impossible to prevent an earthquake from occuring, but the damage to the builiding can be
controlled through proper design and detailing. Hence it is mandatory to do the sesmic analysis and
design to structure against collapse. This study addresses the performance and variation of precentage
steel and concrete quantity of R.C framed structure in different seismic zones and influence on overall
cost of construction. This study mainly focuses on the comparision of percentage steel and concrete
quantities when the builiding is designed for gravity loads as per IS 456:2000 and when the builiding is
designed for earthquake forces in different seismic zones as per IS 1893:2002. A five storied R.C.C
framed structure has been analyse and designed using STAAD ProV8i. Ductile detailing has been done
in conformation with IS:13920
A COMPARATIVE STUDY OF OMRF & SMRF STRUCTURAL SYSTEM USING DIFFERENT SOFTWARESAM Publications
This study is carried out to investigate the seismic behaviour of the structure having various structural configurations
like OMRF (Ordinary Moment Resisting Frames), SMRF (Special Moment Resisting Frames) using different softwares i.e.
Stadd.Pro & Etabs. A comparative study of all the types of frames will shed light on the best suited frame to be adopted for seismic
loads in Indian scenario. For this purpose, a G+6 storey R.C.C. regular building are analysed for OMRCF, SMRCF framing
configurations in Seismic Zone III & IV according to Indian codes. Linear static Analysis or Equivalent static Analysis are carried
out to evaluate their structural efficiencies in terms of storey drifts, average storey displacement, Time period. In OMRF structures
the design and detailing of reinforcement are executed as per the guide lines of I.S. 456-2000 which make the structure less tough
and ductile in comparison of SMRF structures. The basic approach of earthquake resistant design should be based on lateral
strength as well as deformability and ductility capacity of structure .In SMRF structures Beams, columns, and beam-column joints
are proportioned and detailed as per I.S. code 13920(2002) which give adequate toughness and ductility to resist severe earthquake
shock without collapse. Thus it has been observed that SMRF structures behave well in earthquake than OMRF structures.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.
