Structural Materials for Innovative Nuclear Systems (SMINS)
These proceedings include the papers and the poster session materials presented at the workshop, representing the international state of the art in this domain.
Structural materials research is a field of growing relevance in the nuclear sector, especially for the different innovative reactor systems being developed within the Generation IV International Forum (GIF), for critical and subcritical transmutation systems, and of interest to the Global Nuclear Energy Partnership (GNEP). Under the auspices of the NEA Nuclear Science Committee (NSC) the Workshop on Structural Materials for Innovative Nuclear Systems (SMINS) was organised in collaboration with the Forschungszentrum Karlsruhe in Germany. The objectives of the workshop were to exchange information on structural materials research issues and to discuss ongoing programmes, both experimental and in the field of advanced modelling.

Nonlinear analysis methods such as static pushover are globally considered a reliable tool for seismic and structural assessment. But the accuracy of seismic capacity estimates—which can prevent catastrophic loss of life and astronomical damage repair costs—depends on the use of the correct basic input parameters.
Seismic Design Aids for Nonlinear Analysis of Reinforced Concrete Structures simplifies the estimation of those vital parameters. Many design engineers make the relatively common mistake of using default properties of materials as input to nonlinear analyses without realizing that any minor variation in the nonlinear characteristics of constitutive materials, such as concrete and steel, could result in a solution error that leads to incorrect assessment or interpretation.
Streamlined Analysis Using a Mathematical Model
To achieve a more accurate pushover analysis and improve general performance-based design, this book reassesses some key inputs, including axial force-bending moment yield interaction, moment-curvature, and moment-rotation characteristics. It analyzes these boundaries using a detailed mathematical model of reinforced concrete sections based on international codes, and then proposes design curves and tables derived from the authors’ studies using a variety of nonlinear tools, computer programs, and software. The text reviews relevant literature and describes mathematical modeling, detailing numerical procedures step by step.
Including supplementary online material that can be used to compute any parameter, this reference delineates nonlinear properties of materials so that they can be used instantly for seismic analysis without having to solve cumbersome equations.

I suggest a new section creates in the forum on tips that the users could contribute on the managing software. This related to the experience that they have for the managing of the programs
As like for example, some tips on the managing of sap2000, civil3D, revit structure, etc. not necessarily with videoes but they might be descriptions or steps on the resolution of algun problem especially, etc...
Hello
In sap2000 i know how to define wind burdening, but i have probelm wiht passing on the structure, Any idea how to do these,or bether any tutorial (video or pdf),
Tanx in advance!!
The Autodesk Subscription Advantage Pack for AutoCAD 2010 includes a new set of TimeSaver Tools to help you work faster. You can now more easily select and work with objects when editing drawings to help streamline workflows. Several TimeSaver Tools were top AUGI wish-list requests.
New TimeSaver Tools include:
* Hide and isolate objects — Turn objects on and off regardless of layer to save time in tracking objects across layers and quickly show or hide objects as needed.
* Select similar — Select objects with similar properties, such as layer or linetype, or blocks and xrefs with the same names.
* Add selected — Create a new object for your drawing by matching the type and properties of another selected object.
* Hatch to back — Streamline the process of working with hatches by easily selecting hatches and then sending them to the back of the drawing.

ASCE 4-98 (Seismic Analysis of Safety-Related Nuclear Structures and Commentary)
Hi. Anybody has this standarad:
Abstract:
This standard provides requirements for performing analyses for the purpose of new structure design or existing structure evaluation that will lead to the reliability of structures under earthquake motions. The goal of this standard is to provide rules and analysis parameters that are expected to produce seismic responses that have about the same probability of non-exceedance as the input. Specifications of input motions are provided. Analysis standards are given for modeling of structures, analysis of structures, soil-structure interaction modeling and analysis, input for subsystem seismic analysis, and special structures such as buried pipes and conduits, earth-retaining walls, above-ground vertical tanks, raceways, and seismic-isolated structures. Non-mandatory Appendix A provides a discussion on Seismic Probabilistic Risk Assessments and Seismic Margin Assessments.
