I would like to know if anyone knows hot to prevent tekla connects to their servers, for de version 21 and newer they become to use the warehouse, I heard some issues with the law about this, I just want to be sure to block his content.
Also if you guys know how works multi user models with software using medicine.
Hi all,
The new version of ISO 19901-4 has been released in 2016. Please share with us if you do have a new version.

Seismic isolation offers the highest degree of earthquake protection to buildings and their inhabitants. Modern applications of the technology are less than 50 years old and uptake in seismically active regions continues to soar.
Seismic Isolation of Buildings is a comprehensive introduction to the theory and practice in this field. Based on the latest research findings and the authors' extensive experience, coverage includes the application, effectiveness, benefits, and limitations of seismic isolation, as well as the architectural form, design aspects, retrofitting, economics, construction, and maintenance related to this method.
The book is written for an international audience: the authors review codes and practices from a number of countries and draw on examples from eleven territories including the US, Chile, Argentina, Italy, Japan, China, and New Zealand.
Aimed at readers without prior knowledge of structural engineering, the book provides an accessible, non-technical approach without using equations or calculations: instead, over 200 drawings, diagrams and images are used to support the text. Key reading for students on architecture and civil engineering courses looking for a clear introduction to seismic-resistant design, as well as architects and engineers working in seismically active regions.

Finite element analysis (FEA) has become the dominant tool of analysis in many industrial fields of engineering, particularly in mechanical and aerospace engineering. This process requires significant computational work divided into several distinct phases. What Every Engineer Should Know About Computational Techniques of Finite Element Analysis offers a concise, self-contained treatment of FEA and all of the tools needed for efficient use and practical implementation.
This book provides you with a walk-through of the process from the physical model to the computed solution. Based on the author's thirty years of practical experience in finite element analysis in the shipbuilding, aerospace, and automobile industries, it describes the transformation of the physical problem into a mathematical model, reduction of the model to a more efficient, numerically solvable form, and the solution of the problem using specific computational techniques. The author discusses time and frequency domain solutions as used in practice, as well as the representation of the computed results.
What Every Engineer Should Know About Computational Techniques of Finite Element Analysis serves as a to-the-point guide to using or implementing FEA for both beginners and everyday users who must apply the finite element method to your daily work. The techniques can be easily executed in most available FEA software packages.

Author(s)/Editor(s): Anthony C. Fischer-Cripps | Size: 4 MB | Format:PDF | Quality:Original preprint | Publisher: Springer US | Year: 2007 | pages: 226 | ISBN: 978-0-387-68187-0
Introduction to Contact Mechanics, Second Edition is a gentle introduction to the mechanics of solid bodies in contact for graduate students, post doctoral individuals, and the beginning researcher.
This second edition maintains the introductory character of the first with a focus on materials science as distinct from straight solid mechanics theory. Every chapter has been updated to make the book easier to read and more informative. A new chapter on depth sensing indentation has been added, and the contents of the other chapters have been completely overhauled with added figures, formulae and explanations.
The author begins with an introduction to the mechanical properties of materials, general fracture mechanics and the fracture of brittle solids. This is followed by a detailed description of indentation stress fields for both elastic and elastic-plastic contact. The discussion then turns to the formation of Hertzian cone cracks in brittle materials, subsurface damage in ductile materials, and the meaning of hardness. The author concludes with an overview of practical methods of indentation.

Despite the continued rapid advance in computing speed and memory the increase in the complexity of models used by engineers persists in outpacing them. Even where there is access to the latest hardware, simulations are often extremely computationally intensive and time-consuming when full-blown models are under consideration.
The need to reduce the computational cost involved when dealing with high-order/many-degree-of-freedom models can be offset by adroit computation. In this light, model-reduction methods have become a major goal of simulation and modeling research. Model reduction can also ameliorate problems in the correlation of widely used finite-element analyses and test analysis models produced by excessive system complexity.
Model Order Reduction Techniques explains and compares such methods focusing mainly on recent work in dynamic condensation techniques:
- Compares the effectiveness of static, exact, dynamic, SEREP and iterative-dynamic condensation techniques in producing valid reduced-order models;
- Shows how frequency shifting and the number of degrees of freedom affect the desirability and accuracy of using dynamic condensation;
- Answers the challenges involved in dealing with undamped and non-classically damped models;
- Requires little more than first-engineering-degree mathematics and highlights important points with instructive examples.
Academics working in research on structural dynamics, MEMS, vibration, finite elements and other computational methods in mechanical, aerospace and structural engineering will find Model Order Reduction Techniques of great interest while it is also an excellent resource for researchers working on commercial finite-element-related software such as ANSYS and Nastran.

This handbook is a collection of elasticity solutions. Many of the results presented here cannot be found in textbooks and are available in scientific articles only. Some of them were obtained in the closed form quite recently. The solutions have been thoroughly checked and reduced to a "user friendly" form. Every effort has been made to keep the book free of misprints. The theory of elasticity is a mature field and a large number of solutions are available. We had to make choices in selecting material for this book. The emphasis is made on results relevant to general solid mechanics and materials science applications. Solutions related to structural mechanics (beams, plates, shells, etc.) are left out. The content is limited to the linear elasticity.

CSiXRevit is a plugin for Autodesk Revit® that enables bi-directional data transfer to CSI Software products: SAP2000®, ETABS® and SAFE®.
CSiXRevit supports four (4) main workflows of data transfer with Autodesk Revit®:
Exporting from Revit® to create a new CSI Software model.
Exporting from Revit® to update an existing CSI Software model.
Importing from CSI Software to create a new Revit® Model.
Importing from CSI Software to update an existing Revit® Model.
Users have full control over what model data gets transferred and how that data gets mapped to equivalent objects in either software.
