On the argument of this Issue see also the following Website page:
Monitoring Structures.
The subject dealt with in this Bulletin seems quite remote from the worries of the average welder. Nevertheless it should be encouraging to know that besides the great progress done in engineering design and testing, the present trend requires to find ways to install suitable sensors within structures as they are built. The purpose is to know at any time with confidence what is the real structural health condition.
It is hoped that such timely knowledge will reduce the cost of periodic inspection and repair, will prevent the unexpected occurrence of sudden collapse, will give advance notice of impending failures, will ease repair procedures, will help in extending with confidence the useful structure life, will confirm or improve the theoretical design assumptions, will simplify code requirements.
The addresses reported hereafter were live and correct at the time of their publication. There is no guarantee that they will always be so, because they are administered by the sources themselves and are under their control.
Note: References to articles or other documents are given here in
one of two forms. If the links are "live" (usually underlined or otherwise highlighted) they are operated with a click of the mouse.
If they are URL's (Uniform Resource Locator), which is the analogue of an address, they begin with "http://..." or "www.". These are not live and must be copied and pasted entirely into the browser (after having selected them with the mouse or otherwise). If they are long they may be displayed in two or more lines. In that case one has to care that the URL be copied completely in a single line without any space, and Enter.
If the information is important to you, you may save the selected pages in a suitable folder on your Computer for easy reference. You are welcome to forward this page to those of your friends who may profit of this information.
