There are over 1.6 million miles of unpaved roads (53% of all roads) in the United States. In some nations, the road network is predominantly unpaved and generally consists of gravel roads. This manual was developed with a major emphasis on the maintenance of gravel roads, including some basic design elements. Gravel roads are generally the lowest service provided to the traveling public and are usually considered greatly inferior to paved roads. Yet,in many rural regions, the volume of traffic is so low that paving and maintaining a paved road is not economically feasible. In many cases, gravel roads exist to provide a means of getting agricultural products in and out of farm fields, timber out of forests, or as access to remote areas such as campgrounds and lakes. Many gravel roads serve rural residents as well. Many of these roads will remain unpaved due to very low traffic volume and/or lack of funds to adequately improve the subgrade and base before applying pavement layer(s).In some countries, economic constraints mean gravel roads are the only type that can be provided.
The purpose of this manual is to provide clear and helpful information for doing a better job of maintaining gravel roads. It is recognized that very little technical help is available to small agencies that are responsible for managing these roads. Gravel maintenance has traditionally been

The Sixth Edition of this influential best-selling book delivers the most up-to-date and comprehensive text and reference yet on the basis of the finite element method (FEM) for all engineers and mathematicians. Since the appearance of the first edition 38 years ago, The Finite Element Method provides arguably the most authoritative introductory text to the method, covering the latest developments and approaches in this dynamic subject, and is amply supplemented by exercises, worked solutions and computer algorithms.
The classic FEM text, written by the subject's leading authors
Enhancements include more worked examples and exercises, plus a companion website with a solutions manual and downloadable algorithms
With a new chapter on automatic mesh generation and added materials on shape function development and the use of higher order elements in solving elasticity and field problems
Active research has shaped The Finite Element Method into the pre-eminent tool for the modelling of physical systems. It maintains the comprehensive style of earlier editions, while presenting the systematic development for the solution of problems modelled by linear differential equations.
Together with the second and third self-contained volumes (0750663219 and 0750663227), The Finite Element Method Set (0750664312) provides a formidable resource covering the theory and the application of FEM, including the basis of the method, its application to advanced solid and structural mechanics and to computational fluid dynamics.
* The classic introduction to the finite element method, by two of the subject's leading authors
* Any professional or student of engineering involved in understanding the computational modelling of physical systems will inevitably use the techniques in this key text
* Enhancements include more worked examples, exercises, plus a companion website with a worked solutions manual for tutors and downloadable algorithms

Slope stability analysis and stabilization: new methods and insight

Slope stability analysis and stabilization: new methods and insight
By YM Cheng
Publisher: Taylor & Francis
Number Of Pages: 241
Publication Date: 2008-07-25
ISBN-10 / ASIN: 0415421721
ISBN-13 / EAN: 9780415421720
A number of methods currently exist for the analysis and design of slopes. This book provides a critical review of these and offers several more appropriate approaches for overcoming numerical convergence and the location of critical failure surfaces in two-dimensional and three-dimensional cases. New concepts in three-dimensional stability analysis, finite element analysis and the extension of slope stability problems to lateral earth pressure problems are also addressed. It gives helpful practical advice and design resources in the form of recommendations for good analysis and design practice, design charts and tables for the engineer. Limitations are detailed of both limit equilibrium and the finite element method in the assessment of the stability of a slope, and guidance is provided for assessing the fundamental assumptions and limitations of stability analysis methods and computer modelling.The book provides ample examples to illustrate how this range of problems should be dealt with. The final chapter touches on design and its implementation on site. The emphasis is on the transfer of the design to its physical implementation on site in a holistic way, taking full account of the latest developments in construction technology. Engineering and construction problems tend to be pigeonholed into different classes of problem such as slope stability, bearing capacity and earth pressure behind retaining structures. This is quite unnecessary. This book offers a unified approach, which is conceptually, practically and philosophically more satisfying.

Elementary Behaviour of Composite Steel and Concrete Structural Members

Elementary Behaviour of Composite Steel and Concrete Structural Members
By Deric Oehlers, Mark A. Bradford
Publisher: Butterworth-Heinemann
Number Of Pages: 280
Publication Date: 2000-02-14
ISBN-10 / ASIN: 0750632690
ISBN-13 / EAN: 9780750632690
This book is aimed at developing elementary analysis skills, familiarity and an intuitive feel for composite construction that is required by undergraduate and graduate students, and by structural engineers. It does not require a prior knowledge of advanced analysis and design techniques, and builds on simple concepts such as statics and the mechanics of materials. A topic is first introduced by a brief description, with numerous carefully-chosen examples forming an integral part of the main text. Working through the examples allows the reader to gain a full understanding of the subject, as a technique is illustrated by its application to designing new structures, or in the important area of assessing and upgrading existing structures.
The techniques described for the analysis of standard structures form a basis for understanding the way composite structures work, and these techniques are applied to many non-standard forms of composite construction that are not, or rarely, covered in national standards. The book is an essential purchase for all undergraduate and postgraduate students of structural/civil engineering and architecture, as well as all practising structural and civil engineers.
Covers practical applications not covered in codes, such as service ducts, splitting, upgrading existing structures and non-standard forms of composite construction
Topics are embellished by working through numerous unique and carefully-chosen examples that form an integral part of the subject material
Not orientated to specific codes, so that principles can be applied to any national design standard

(1) Cracks from our VIP forums are published at other sites. I saw our PERFORM 3D crack published at another site. VIP members shall be requested not to publish that.
(2) TENTEASTE has contributed two great cracks to the forum : SAP2000 V14 and STRAP 2009. Some other cr**rs are downloading this cracks from our forum and publishing it with their names. I think this really discourage him.
I request ADMIN and MODERATORS to allot VIP or equivalent post to TENTEASTE, seeing his contribution to our forum. If he is able to put his contribution in VIP section, outsiders may not misuse it. ADMIN and MOderators may decide to put his contribution to general forum if they wish.
Plz note i am not favouring anyone, but i tell what i feel is better to our forum. FInal decision will be of our ADMIN and MOderators.
1. I've noticed that some people (even I perhaps) on the forum write nonsense. They are posting unnecessary thanks and they constantly offtopic and spam. It's great for someone to know that he/she/it is doing something great but it's frustrating to read a thread full of thanks until you get to something that is useful to you. If there are positive reputations, why there are no negative, BUT that kind of negative reputation, which gives only the administrators and moderators in a way to delete useless posts and write a negative reputation, and explanation for it. So, for example, 10 negative reputation follows bann or some kind of warning to the member (even if that member is I). I think that's the only way that people learn to read the forum rules and stick to them.
If anybody wants to say thanks/ excellent/ good_posting/ have_a_great_day/ etc., please use the THANKS button.
2. Same thing on writing not_english. I understand (not every thing) when someone write on spanish but why write spanish or other language when everybody write english. My mother tongue is croatian and i'm not good in english, but if I can use some of Internet dictionaries if I can't remember some of words so can others. Try google translate, eudict, etc. Google is your friend!
(If extremely needed i would try my best to translate this post to any other language just to be understood by all others no_english_understanding_people) ;):D
3. Just one more request (if possible) - is there a way to delete/ remove empty pages in threads? For example in the thread
