Dear business partner,

we are happy to present you our Newsletter July 2013. It contains the information about the development in our continuous effort to bring the latest achievements in the numerical modeling of reinforced concrete to your desk.

Development of ATENA, version 5

The testing of ATENA Version 5 continues, now with a wider group of beta-testers. We collect their comments, bug reports, and improvement suggestions till the end of July. Then, we plan to release version 5 after incorporating any important fixes.

The major features of this new version are among others:

• Atena Studio - new integrated 2D/3D environment for runtime analysis control and post-processing.
• Model CERHYD - modeling of hydration heat development, shrinkage, creep and cracking in young concrete.
• Improved transport model - supports nonlinear analysis of coupled heat and moisture transport in concrete.
• Improved documentation - the software package contains 4 books covering theory, tutorials and software user's manual.
• Improved nonlinear solver - with new features for more robust convergence, such as: automatic restart and step length reduction, selection of best iteration results.

ATENA Advanced User Seminar

Czech Republic-Prague, June 12-14, 2013

The seminar has been targeted for advanced ATENA users, who wants to learn more about the theoretical background of ATENA and its advanced application areas such as ATENA 3D, GiD-pre/post-processing, dynamic, eigenvalue, creep, thermal, or fire analysis.

The new ATENA version 5 was presented and used throughout the seminar.

This new version includes a totally reworked runtime and postprocessing environment ATENA Studio, which replaces the previous program ATENAWin, and represents the basis for future ATENA development.

The main focus will be on the package ATENA Science, which includes an updated GiD interface and new features for modelling concrete hydration, seismic and pushover analysis.

ATENA Troubleshooting Manual

Have you already known that the most frequent questions and problems with ATENA are solved in the ATENA Troubleshooting Manual? The document is included in ATENA installation, and the current version is also available for separate download from out web:

http://www.cervenka.cz/products/atena/documentation/

You can find there all the other manuals, too.

Computer model for high-performance fibre reinforced concrete material

Funding agency: Czech Technological Agency, project no. TA03011564

The project result will be a computer model/software for the design and assessment of civil engineering structures from ultrahigh performance fibre reinforced concrete with higher durability and reliability. Currently there are practically no suitable methods and models for the structural design using these materials, even though their usage is expected to grow significantly in the future.

Their advantage is higher durability and strength, which enables engineers to build structures with longer lifecycle, lower material consumption and lower impact on the environment.

The developed numerical model will enable predictive numerical analyses of short-term and long-term behaviour of structures from ultrahigh performance fibre reinforced concrete in the service limit states as well as in the ultimate limit states.

The wider objective of the proposed project is to support the application of these modern materials in the construction of new structures as well as in the maintenance of the existing ones and to increase their durability and reliability.
