Vibro Replacement is an accepted method for subsoil improvement, at which large-sized columns of coarse backfill material are installed in the soil by means of special depth vibrators. The performance of this composite system consisting of stone columns and soil, is not determinable by simple investigation methods like soundings, and therefore, such methods are not suitable for design purposes. However, theoretically, the efficiency of Vibro Replacement can be reliably evaluated. The method elaborated on a theoretical basis and described in this contribution, is easy to survey and adaptable to different conditions due to the separate consideration of significant parameters. Practically, it comprises design criteria for all frequently occurring applications.

The purpose of this manual is to guide the districts in conducting geotechnical investigation and design for project development.
Information in this manual is organized into the following chapters:
1. Manual Overview. Introductory information on the purpose and organization of the manual.
2. Soil Surveys. Requirements for conducting soil surveys for projects with bridges, retaining walls, slopes and embankments, sign structures, illumination, sound walls, and radio towers.
3. Field Operations. Requirements for drilling, sampling, and field testing.
4. Soil and Bedrock Logging. Description of material order, level of description, and classification.
5. Foundation Design. Guidelines for selecting foundation types, drilled shafts, piling, and requirements for scour analysis.
6. Retaining Walls. Requirements for retaining wall selection, layouts, design, and excavaton support.
7. Slope Stability. Requirements for slope stability design and analysis.

I really need a help. I have thousand files of RUAUMOKO's output data in text format that arranged neatly in folders with sequences numbers of file naming. Each file is containing the data that I must collect as shown inside the red lines in the following picture:
Is there anyone here had a program to tackle this problem?
Your help would be highly appreciated.
best regards.
in bridge wizard the elevation of the bearing can be defined, but the horizontal distance of the bearing can not be assigned, and this issue has troubled me for a long time , any one could help?
Dear All,
I am doing some research relating to story ductility ratios. I am using Sap2000. The problem is that i have to carry out a lot of iterations and hit and trials. I needed to know is there any simplified software or excel sheet which i can modify.
Thanks.
Characteristics Finite Element Methods in Computational Fluid Dynamics
Book Title: Characteristics Finite Element Methods in Computational Fluid Dynamics
Author: Joe Iannelli
ISBN:3540251812
Publisher: Springer,1 edition October 5, 2006
File: 11.4 MB PDF, 727 pages
Description:
This book details a systematic characteristics-based finite element procedure to investigate incompressible, free-surface and compressible flows. Several sections derive the Fluid Dynamics equations from thermo-mechanics principles and develop this multi-dimensional and infinite-directional upstream procedure by combining a finite element discretization with an implicit non-linearly stable Runge-Kutta time integration for the numerical solution of the Euler and Navier Stokes equations. Based on the mathematics and physics of multi-dimensional characteristics, convection as well as acoustics, and inducing by design a controllable multi-dimensional upwind bias that can be locally optimized, the procedure crisply captures contact discontinuities, normal as well as oblique shocks, and generates essentially non-oscillatory solutions for incompressible, subsonic, transonic, supersonic, and hypersonic inviscid and viscous flows with chemical reactions and work, heat and mass transfer.
