I usually sign/log in to my account on different PCs and sometimes forget to sign out.
This has happened on so many occasions. Recently i logged into my account using someones laptop who later traveled off to some place far. I worry that these people might access my account without my permission.
How can i prevent this now that i can not recall any of them well.
If i log off on my PC and log back in, it does not help at all. On their machines i stay logged in!!! Computer gurus please help out regarding this matter.
Is there any other advanced way of logging out completely from all these PCs so i can only log in using my PC? , whether remotely?
I was wondering what is the best and easiest to learn software for FEM/FDM analysis in geotechnics?
There is Plaxis which has lots of advantages, especially regarding Rocsciences Phase 2D. I would put Geostudio somewhere in between that two. But is there something else.
Of course, this three mentioned works with FEM. Other known is FLAC (FDM).
There are some other softwares like Soilvision, GEO5, MIDAS... but which is the best, and simplest.
Best regards

This European Standard specifies test methods for determining the strength and deformation characteristics of
laterally loaded connections with nail, screws, dowels and bolts in load-bearing timber structures.
The methods assess connections with members of timber (solid timber or glued laminated timber) or wood-based
products or metal plates (but not punched metal plate fasteners) in the combination proposed for use in service.
The methods are used to determine load-slip characteristics and maximum load of connections where various
angles between the applied force and the timber grain direction, or the main direction of the wood-based products,
respectively, are possible.

THERMAL RESPONSE OF REINFORCED CONCRETE STRUCTURES IN NUCLEAR POWER PLANTS
Author: Kaspar Willam, Yunping Xi , Keun Lee and Byunhun Kim | Size: 7.7 MB | Format:PDF | Publisher: University of Colorado at Boulder | Year: 2009 | pages: 210
This is the report for a research project sponsored by Oak Ridge National Laboratory in 2008 –
2009. The objectives of the project were to review and summarize thermal responses of
reinforced concrete structures used in nuclear power plants. There are totally three parts of the
report. The first part focuses on responses of various materials under high temperatures
including concrete and steel, the second part on structural performances, and the third on spalling
damage of concrete under high temperatures.
The first part of the report includes several aspects: damage mechanisms of the materials under
high temperatures, available experimental results, current code specifications, and prediction
models for thermal responses of the materials. The material properties include strength, stiffness,
stress-strain relations, transport properties (e.g. thermal conductivity), short-term thermal
expansion, long-term thermal creep, shrinkage, and the interactive effects among temperature
variation, vapor diffusion, and mechanical loading in concrete. The bond behavior between
concrete and steel under high temperatures is also included. This part is listed as the first part of
the report, because thermal responses of reinforced concrete structures used in nuclear power
plants depend on thermal responses of materials such as concrete and steel under high
temperatures.
The second part of the report focuses on the structural responses of reinforced concrete structures
under high temperatures, such as beams, columns, and slabs. The second part of the review
includes available experimental results, current code specifications, and prediction models for
thermal responses of the reinforced concrete structures. In addition, we developed a numerical
model for characterizing high temperature responses of reinforced concrete beams. The model
prediction was compared with available test data in the literature and with predicted results by a
commercial finite element code.
The third part of the report is for spalling damage of concrete under high temperatures, which is
a special form of fire damage when the heating rate is very high. The review includes
experimental results, damage mechanisms, and theoretical and numerical analysis. A recently
developed numerical model and experimental results obtained by the authors were described in
detail together with a comprehensive literature review on spalling damage of concrete.

Author: C E MacKenzie, C-H Wang, R H Leicester, G C Foliente, M N Nguyen | Size: 2.7 MB | Format:PDF | Publisher: Forest and Wood Products Australia | Year: 2007 | pages: 115 | ISBN: 978-1-920883-16-4
This guide provides information to assist timber industry employees, timber users
and specifiers of timber to select members and structures with respect to their
service life requirements. The information provided has been derived from historical
performance and field and laboratory research and experience. The outcomes from
a 10-year multi-million dollar ‘world first’ research project to develop a probabilistic
durability design method for timber have also been incorporated in this publication
where appropriate.
The guide addresses in detail specific hazards with respect to the service life of timber
construction subject to the following hazards:
In-ground decay
Above ground decay
Weathering
Termites
Corrosion
Marine borers
More detailed information associated with timber performance for other hazards
including fire resistance and chemical degradation should be obtained from other
sources.
Better or more cost-effective performance is achieved with better knowledge. Thus,
it is expected that with time, this guide will be updated to reflect contemporary
knowledge and research outcomes. This may include coverage of alternative
preservative treatment processes such as ACQ, Copper Azole, and others, which are
now referenced in Australian Standards and State legislation.
This Guide is a complimentary publication to two other valuable timber durability
design resources that are outcomes from the Forest and Wood Products Australia
Durability Design Project completed in 2007.

CivilEAns, I am very much interested in low cost housing projects.
In case amongst us, there some with papers, journals, books, or anything else pertaining to this, please avail some time and try uploading. It will be so much appreciated.
Equivalent Static vs. Response Spectrum A Comparison of Two Methods
By David T. Finley, Ricky A. Cribbs
6 Pages
0.5 MB rar file size
In recent years the state of the art of seismic analysis has increased along with the delopment of technology. The developments in computer hardware and software have made analysis techniques which were formerly too expensive within the reach of most project budgets. Foremost among these has been the response spectrum analysis method for seismic analysis.
In this paper we will review the basics of equivalent static and response spectrum analyses, and their specific use in the analysis and design of an optical telescope. We will compare and contrast response spectrum analysis with the more typical equivalent static analysis, and point out conditions in which one would be preferred over the other. In addition, correct interpretation and use of analysis results will be discussed. These issues will be investigated and discussed using the ongoing VISTA optical telescope structure as an example.

You may want to look at this book. It is old but covers a lot what you are looking for.
Best of luck.
