Advances in Earthquake Engineering for Urban Risk Reduction

[Image: 27836338415868831722.jpg]

* Publisher: Springer
* Number Of Pages: 551
* Publication Date: 2006-06-30


Description:
Earthquakes affecting urban areas can lead to catastrophic situations and hazard mitigation requires preparatory measures at all levels. Structural assessment is the diagnosis of the seismic health of buildings. Assessment is the prelude to decisions about rehabilitation or even demolition. The scale of the problem in dense urban settings brings about a need for macro seismic appraisal procedures because large numbers of existing buildings do not conform to the increased requirements of new earthquake codes and specifications or have other deficiencies. It is the vulnerable buildings - liable to cause damage and loss of life - that need immediate attention and urgent appraisal in order to decide if structural rehabilitation and upgrading are feasible. Current economic, efficient and occupant-friendly rehabilitation techniques vary widely and include the application either of precast concrete panels or layers, strips and patches of fiber reinforced polymers (FRP) in strategic locations. The papers in this book, many by renowned authorities in earthquake engineering, chart new and vital directions of research and application in the assessment and rehabilitation of buildings in seismic regions. While several papers discuss the probabilistic prediction and quantification of structural damage, others present approaches related with the in-situ and occupant friendly upgrading of buildings and propose both economical and practical techniques to address the problem.

  Theory and Design of Seismic Resistant Steel Frames

Theory and Design of Seismic Resistant Steel Frames

Theory and Design of Seismic Resistant Steel Frames
By Mazzolani

* Publisher: Routledge
* Publication Date: 1996-05-01

Theory and Design of Seismic Resistant Steel Frames is a state-of-the-art summary of recent developments in the behaviour, analysis and design of seismic resistant steel frames. The book provides advanced students, researchers and professionals in civil and structural engineering with the basic principles upon which the modern seismic codes are based. It deals with all recent developments in seismic design of steel frames, and illustrates how these can be used to improve design rules. The book is much more than a simple background volume, giving the most recent results which can be used to improve the codified recommendations for steel structures in seismic zones. It contains new material which cannot be found in any standard reference book on seismic engineering. The important issues in seismic design of steel frames, such as the evaluation of the local and global ductility, and the evaluation of the q-factor, are fully discussed. In addition, the authors closely examine the influence of second order effects and connection behaviour. Particular attention is devoted to the problems related to the influence of geometric configuration and of random material variability.

  Protect your system without using AV software
Posted by: PrinceOfHeartz - 01-16-2010, 07:11 PM - Forum: Free Discussion - Replies (8)

Here's a tip to protect your system from virus attacks (mainly from the internet) even if you don't have a an AV software installed. Most of the users create only one user account in Windows. So, that one account will act as the administrator. The viruses reaching the system via that user account will have full access to every part of the operating system including registry. So they are allowed to function normally.
Now what you have to do is, create another user account having no adminstrative previlages and then onwards use that account for surfing the net. Even if some viruses reach the system, they won't get access to the key areas because the user has no administrative rights. So your operating system will be protected from viruses coming from the internet.

Note: This is not an excuse for not installing an AV software. It is always recommended to install an AV software. This tip should only be considered as a preventive measure. But it is true that sometimes it can protect your OS from viruses even if you don't have an AV software installed.

Regards,

  Math Mechanixs 1.4.0.4
Posted by: BennyP - 01-16-2010, 10:20 AM - Forum: Non Engineering Software - Replies (1)

Math Mechanixs 1.4.0.4

[Image: info.png]
Math Mechanixs is a versatile and powerful mathematical analysis tool. Math Mechanixs is as easy to use as a common calculator is and may be used by high school students, college students, engineers and scientists.

Math Mechanixs does not work like a conventional calculator. Math Mechanixs understands the mathematical language as opposed to a calculator, which only understands keystrokes on the buttons. Because Math Mechanixs is capable of understanding the language of mathematics, you can communicate with Math Mechanixs simply by typing a mathematical expression into the Math Editor the way that you would write it on a sheet of paper. This allows you to describe the problem using words in addition to solving the problem mathematically. After you have completed the problem you can save it to a file and send the file to a printer.

The Function Library also includes a unique feature designed to provide a convenient graphical user interface (GUI) for solving any defined function. This utility is called the Function Solver. The function solver works with any predefined or embedded function including user defined functions.


This software works 30 day in Evaluation Mode and after 30 days in Evaluation Lite Mode.
Moving the clock forward before installation will add the same time interval.
In case you forgot to do that use regedit and delete the folowing keys:

  The Haitian tragedy
Posted by: chigozie - 01-16-2010, 09:15 AM - Forum: Free Discussion - Replies (2)

On Tuesday the 12th of this month (January 2010), at about 16.00 hours local time, 7.0 magnitude earthquake struck the American country of Haiti. It was that bad that the presidential building and the United Nations buildings also collapsed. It is estimated that more than 200,000 people lost their lives. The United Nations could not account for some of its staff including the head of its operation in Haiti. Many more are still trapped in rubbles. Thousands were seriously injured. What part did civil engineering play in this tragic event and what part should it play in the reconstruction of this unfortunate poor nation?

Many of the software contact their servers without our knowledge. We think that the software is updating. Many of the software developers say that no personal information is exchanged with the server. But are you sure? :ihih: I'm not.

A firewall can not only prevent unauthorised access from the internet, but can also prevent unauthorised access to the internet. It is always good to check what all programs are trying to access the internet by using your firewall (either an independent one or the one in your security suite). If you find something suspicious, block it. :yes:

When you think about software, you should think about your operating system also. You can turn off the update feature easily. But you need the crucial updates don't you?
I think softwarepatch.com is a good website from which you can download updates and patches.

Regards,


I hope that you realise the importance of this thread. Especially since many of the users are using p*rtd software.
oops. Sorry! I forgot to put the link within code tags. Sorry mods. I couldn't find an edit button. So I couldn't edit it. Sorry.
