The use of inhibitors for rehabilitation of reinforced concrete structures is a new field of application and this new volume provides a State of the Art Report on this subject. Corrosion of steel in concrete is one of the major problems for infrastructure such as bridges, tunnels, housing etc. since it leads to spalling of the concrete and loss in cross section of the steel that may cause structural and safety problems. The steel in concrete generally resists corrosion as a result of a passive layer that develops on the metal surface in the alkaline environment of the concrete. Corrosion can occur if these conditions are disturbed, for example, in the presence of chlorides or with carbonation of concrete. Traditional repair methods consist in removing the deteriorated concrete and replacing it but these can be laborious, noisy and very costly. To avoid these disadvantages new methods have been developed in recent years. These include electrochemical procedures and, increasingly, the use of inhibitors. The use of inhibitors for rehabilitation of reinforced concrete structures is a new field of application and this new volume provides a State of the Art Report on this subject. The report, under the editorship of Prof. Bernhard Elsener, was prepared by a Task Group of the EFC Working Party on Corrosion of Reinforcement in Concrete. In a literature review it describes inorganic and organic chemicals that have been proposed and examined as well as the commercial corrosion inhibitors that are available on the market. Protection mechanism and possible effects of inhibitors on concrete properties are described. Practical experience with inhibitors for steel in concrete and the long term effectiveness are considered. The various test methods for evaluating the behaviour of the inhibitors are described and critically assessed. In a rapidly evolving field this State of the Art Report, based mainly on independent not commercial literature, will be of value to corrosion engineers and civil engineers concerned with maintenance and repair of reinforced concrete structures.

SAFE is the ultimate tool for designing concrete floor and foundation systems. From framing layout all the way through to detail drawing production, SAFE integrates every aspect of the engineering design process in one easy and intuitive environment. SAFE provides unmatched benefits to the engineer with its truly unique combination of power, comprehensive capabilities, and ease-of-use.
Laying out models is quick and efficient with the sophisticated drawing tools, or use one of the import options to bring in data from CAD, spreadsheet, or database programs. Slabs or foundations can be of any shape, and can include edges shaped with circular and spline curves.
Post-tensioning may be included in both slabs and beams to balance a percentage of the self-weight. Suspended slabs can include flat, two-way, waffle, and ribbed framing systems. Models can have columns, braces, walls, and ramps connected from the floors above and below. Walls can be modeled as either straight or curved.
Mats and foundations can include nonlinear uplift from the soil springs, and a nonlinear cracked analysis is available for slabs. Generating pattern surface loads is easily done by SAFE with an automated option. Design strips can be generated by SAFE or drawn in a completely arbitrary manner by the user, with complete control provided for locating and sizing the calculated reinforcement. Finite element design without strips is also available and useful for slabs with complex geometries.
Comprehensive and customizable reports are available for all analysis and design results. Detailed plans, sections, elevations, schedules, and tables may be generated, viewed, and printed from within SAFE or exported to CAD packages.
SAFE provides an immensely capable yet easy-to-use program for structural designers, provideing the only tool necessary for the modeling, analysis, design, and detailing of concrete slab systems and foundations.

We all love our forum CivilEA, it gives us so much, in return we have to do our part.
This is the cleanest, best organized forum there is.
In searching the forum we always come across this broken so called "Dead Links"
I was just wondering if somebody among us knows a way to figure out to find these Dead Links ahead of the time , so it can be sorted and made available to whomever wants to spend time to refresh them, if he/she has the material.
Currently status of this matter is time consuming. ( I personaly check the new posts, to see if it is about a Dead Link, then I search my Archives for the request.)
If somebody finds a dead link, he/she posts a request for it, and may be in couple of days it is refreshed by a Good Soul.
I think finding a shortest way for this would make our forum, very dynamic, and it will attrack more users, too. This would translate into new material, new horizons for everybody.
A lot of times users request a new link, but in reality there would be some links alive in the thread among the posts.
I am studying the piled slope and require the following documents to support it:
1. Ginzburg L.K., 1988. Stabilization of Landslide Slopes By Pile Structures, Proc. 5th
International Symposium on Landslides, Lausanne, 10-15 July, Vol.2, 915-919
2. Sommer H., 1977. Creeping Slope In Stiff Clay, Proc Specialty Session 10, 9th
International Conference on Soil Mechanics and Foundation Engineering, Tokyo.
3. Yamagami T., Jiang J., Ueno K., 2000. A Limit Equilibrium Stability Analysis of
Slopes With Stabilizing Piles, Slope Stability 2000, ASCE STP 101.
Really appreciate if you could share those literatures to me
A readable and user-friendly introduction to fluid mechanics, this high-level text is geared toward advanced undergraduates and graduate students. Mathematicians, physicists, and engineers will also benefit from this lucid treatment.
The book begins with a derivation of the equations of fluid motion from statistical mechanics, followed by examinations of the classical theory and a portion of the modern mathematical theory of viscous, incompressible fluids. A considerable part of the final chapters is devoted to the Navier-Stokes equations. The text assumes a familiarity with functional analysis and some complex variables, and it includes an especially valuable discussion of the modern function theoretic approach to solving partial differential equations. Numerous exercises appear throughout the text.

In 1989, the Steel Construction Institute produced publication P076[1] entitled ‘Design Guide on the Vibration of Floors’. From vibration measurements taken over the last 10 years on steel-framed floors, it was decided that a new version of the publication was required: to extend the guidance to new forms of construction (such as Slimdek®); to include guidance on special floors (such as dance floors); and, from calibrating numerical models against test performance, to develop a new design methodology.
Following the publication of P354[2] entitled ‘Design of Floors for Vibration: A New Approach’, P076 and P331[3] have been withdrawn. This article reviews the new publication, indicating and explaining changes.

Mechanics and model-based control are both rapidly expanding scientific fields and fundamental disciplines of mechatronics, sharing demanding mathematical and system-theoretic formulations and methods. The papers in this volume deal with smart materials, which allow the design and implementation of new types of actuator/sensor fields and networks. Main topics treated are fundamental studies on laminated, composite and functionally graded materials, thermal and piezoelectric actuation, active and passive damping, as well as vibrations and waves in smart structures. The book is based on the 1st Japanese-Austrian Workshop which took place in Linz in Fall 2008.

This guide was prepared for two reasons. Firstly, the introduction of BS 5950-1:2000 highlighted the need to check the sway stability of all frames, including braced frames. Whilst this was required in the 1990 version of the Standard, common practice was to ignore the check for braced frames. Frame stability checks are therefore relatively new in practice, and deserve explanation. Secondly, no complete guide existed for what is a very important form of construction in the UK – multi-storey steel-framed buildings.
Whilst the design of elements within a frame, such as beams and columns, is covered elsewhere, and is not of itself particularly challenging, a guide covering the wider aspects
of multi-storey design was considered to be a valuable addition.
This guide does not attempt to repeat exhaustive coverage on the design of elements if these are covered elsewhere, but directs the reader to the resources that already exist.
Instead, the guide offers advice on layout, floor systems and typical element sizes, so that the scheme design can be carried out with confidence.
