The Timoshenko beam theory includes the effects of shear deformation and rotary inertia on the vibrations of slender beams. The theory contains a shear coefficient which has been the subject of much previous research. In this paper a new formula for the shear coefficient is derived. For a circular cross section, the resulting shear coefficient that is derived is in full agreement with the value most authors have considered "best." Shear coefficients for a number of different cross sections are found.

Dear Admin
I hope to be fine
My Suggestion is creating a new section for general repairing specially repairing concrete
and the new section will include the following
1. repairing concrete , roads , railways , buldings , steel structure , etc
2. all related videos , photos , papers , and also books should be posted in this section
and moving all related Subjects in the fourm to this sec.
3. the materials which are using in reparing and its datd sheets
4. the famous companies in the repairing field and its products
5. the concrete admix. and its effects in concrete characteristics
from my side , the modefications on my Suggestion are available for all
regards

Analytic Element Modeling of Groundwater Flow
Author: H. M. Haitjema
Publisher: CLASSPAK at Indiana University | 1995 |
ISBN 0123165504 | PDF | 394 pages | 23.82 MB
Description of Book:
Modeling has become an essential tool for the groundwater hydrologist. Where field data is limited, the analytic element method (AEM) is rapidly becoming the modeling method of choice, especially given the availability of affordable modeling software. Analytic Element Modeling of Groundwater Flow pres all the basics necessary to approach AEM successfully, including a presentation of fundamental concepts and a thorough introduction to Dupuit-Forchheimerflow. This book is unique in its emphasis on the actual use of analytic element models. Real-world examples complement material presented in the text.
An educational version of the analytic element program GFLOW is included to allow the reader to reproduce the various solutions to groundwater flow problems discussed in the text. Researchers and graduate students in groundwater hydrology, geology, andengineering will find this book an indispensable resource.
* Pres a fundamental introduction to the use of the analytic element method.
* Offers a step-by-step approach to groundwater flow modeling.
* Includes an educational version of the GFLOW modeling software.

EN 996:1995+A3:2009 Piling equipment - Safety requirements
1.1 This standard specifies safety requirements for piling equipment suitable for the following purposes:
a) Construction of foundations, slurry walls or retaining walls, using piles or other longitudinal elements;
b) Removal of piles;
c) Installation of drain or injection elements.
The pile material can be timber, concrete (precast or cast in situ) or steel (tubes or rolled sections). Additionally, piles may have an interlocking feature to enable adjacent piles to be joined together.
1.2 This European standard deals with all significant hazards pertinent to piling equipment, when they are used as intended and under the conditions foreseen by the manufacturer (see annex A) associated with the following:
- Transport of equipment;
- Rigging and dismantling of equipment;
- Equipment in service and out of service;
- Moving of equipment between pile positions;
- Storage of equipment.
This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards.
1.3 Piling equipment includes:
a) Piling rig consisting of carrier machine (crawler, wheel or rail mounted, floating), leader attachment, leader or other guiding systems, e.g. direct mounted, boom supported, swinging, guide cage or free riding;
b) Pile installation and extraction equipment, e.g. impact hammers, extractors, vibrators or static pile pushing/pulling devices;
c) Accessories, e.g. pile caps, helmets, plates, followers, clamping devices, pile handling devices, pile guides, acoustic shrouds and shock/vibration absorbing devices, power packs/generators and personnel lifts or platforms.
1.4 In addition, this standard applies to diaphragm walling rigs. Additionally, the particular requirements which apply to diaphragm walling equipment are given in normative annex C.
