Does anyone know how to render rebar in Revit Structure 2010.I tried everything(well nearly everything) but still can't get no results.Rebars are created with Revit extension,option "Automatic Reinforcement Generation".
I can see rebar in 3D view(view unobscured box checked).I you have any suggestion,please share.
Hi to all. I want to ask a question about this program. I have a tunnel (TBM) and i want to find the axial stiffness (EA) and the flexular rigidity (EI) of the segmented lining (rings). The young modulus is known (35 GPa) and i want yr opinion about this.
Thank u
Description:
Complex problems in geotechnical engineering and soil mechanics can be investigated with physical modelling, where the structures in a geometrically n-times smaller scale are reproduced and the occuring forces and deformations are measured. Problematic is the reduction of pressures and the subsequent change of the mechanical behaviour of the model soil. The versatility of field and model test is shown by examples from the literature. In this thesis the similarity between barotropy and pyknotropy was used to model prototype soil behaviour. Soiltron is a prototype soil, which is treated with light and soft additives to achieve the same relative density in the model at an n-times smaller pressure as in the prototype. The stiffness and strength of the new material can be influenced to simulate prototype material behaviour by the control of the soil density. Thus, the use of that soil as material in small scale models is possible. At the Institute of Geotechnical and Tunnel Engineering of the University of Innsbruck a model soil material was not available in sufficient quantity. Therefore, a large quantity of quartz sand was purchased and its mechanical behaviour was investigated in detail with triaxial test devices using local strain gauges. The specimen deformations were inspected with evaluation of remote measurements using PIV. Systematic and random test errors have been avoided or have been taken into account. Appropriate regressions have been found to relate pressure and density to the properties of the soil and to calculate the required density of Soiltron. The appropriateness of Soiltron is verified in two demonstration model tests. This work can be seen as foot step to strike a new path in physical modelling.
GUIDELINES FOR GEOTECHNICAL INVESTIGATION
UAE - ABU DHABI MUNICIPALITY ROAD DEPARTMENT
This document is a compilation of recommended good practices for geotechnical investigation.
The document delineates the sequential stages that a normal geotechnical investigation program requires and describes the purpose and scope of work for each of those steps. Descriptions of technical requirements for site works, laboratory works, and reporting are covered in general.
Indexes of specific, internationally accepted standards1 pertinent to subsurface investigation are included in the appendices. This document is intended as a reference tool. The requirements and practices described are
general guidelines and are to be viewed as such. The document is not intended to be definitive in its scope or to provide detailed guidance on every type of subsurface investigation in every type of condition. Prevailing ground conditions and details of a project at hand will finally dictate actual requirements (see Section 3.3.2.6).
The contents of this document are based on good engineering practice and internationally accepted standards, and the Abu Dhabi Municipality Road Department (herein referred to as the Department) expects these practices and
standards, as applicable, to be followed as a matter of course in geotechnical investigations.
These should be considered minimum standards.
Specifications that are more detailed or standards that are more appropriate may be required, depending on a specific project’s needs.

The Landslide Handbook -A guide to understanding Landslides
This handbook is intended to be a resource for people affected by landslides to acquire further knowledge, especially about the conditions that are unique to their neighborhoods and communities. Considerable literature and research are available concerning landslides, but unfortunately little of it is synthesized and integrated to address the geographically unique geologic and climatic conditions around the globe. Landslides occur throughout the world, under all climatic conditions and terrains, cost billions in monetary losses, and are responsible for thousands of deaths and injuries each year. Often, they cause long-term economic disruption, population displacement, and negative effects on the natural environment.

Review (vol1):
This book constitutes the first six chapters of what, with Volume II, is to be a text with a total of 13 chapters. The 6 chapters at hand comprise a careful and focused review of the central concern of the author's research for more than 3 decades: the problems of oscillation and general structural instability induced by the axial flow in and around pipes, the representative paradigmatic example being the "fire hose" or jet-follower instability problem.
While avoiding a claim of exhaustive treatment, the text does in fact offer a very detailed, thorough and exacting analytic and bibliographical coverage of many aspects of axial-flow pipe problems, certainly more than any other text. ... The work is clearly a labor of sustained dedication and care. The author has enlivened it in places with brief anecdotal material from practical situations. As he hints, he does not wish to risk boring the reader. He aims the text at engineers and applied mathematicians, especially researchers and practicing professionals. All of these should welcome it as an unusual, responsible, and highly valuable reference."
-Robert H. Scanlan, Journal of Fluids and Structures
"This book is the first of two volumes that focus on the fundamentals of flow-induced vibrations. Both the causes of vibrations and the symptoms are discussed, along with some long-term preventive measures. The author stresses the benefits of discovering the source of the vibration and solving the vibration problems rather than adding a buffer to reduce vibratory effects. The text begins with a general overview of the topic and a classification of flow-induced vibrations. A brief description of the contents of volume 2 is also given
Review(vol2):
"With the second volume of Fluid-Structure Interaction, Michael Paidoussis has completed a comprehensive and unique two-volume book on fluid-structure interaction in axial flows. Throughout the book the author provides detailed, well-illustrated applications of the subjects treated, some of which are in traditional areas of engineering and some in the rapidly developing new field of bioengineering.
The emphasis is on physical understanding of the problems, and as a result the treatment is biased towards analytical and semi-analytical methods, but comparison with experiments is extensive and systematically provided, using well-thought-out figures, graphs and photographs. Great care is taken to explain several fine points and resolve apparent paradoxes that have been at the centre of controversy over the years.
Theoretical results are always presented side-by-side with detailed and careful comparisons with experiments; this gives great strength to the arguments and derivations. The author possesses an unmatched expertise in the area, and his knowledge of the literature, which spans several decades, and mastery of all developments is impressive. The exposition is very detailed, but at the same time clear, starting from basics and proceeding to the most complex phenomena; the various chapters are self-contained. This book will be a very valuable source for graduate courses on hydroelasticity, where by necessity only subsets of the book can be covered, while it will be an essential reference for workers in the field. The author states that the book has been written for engineers and applied mathematicians; its uniform and systematic treatment of a vast field does indeed provide invaluable service both to engineers and theoreticians.
In conclusion this is the definitive book on hydroelasticity in axial flow, an essential source for the researcher, but also a valuable textbook for the graduate student a very unusual and valuable book indeed. One must marvel at the amount of work and care that must have been devoted to writing such a book - it is a pleasure to read and a rich source of information. It is highly recommended to libraries and as course material."
