SLOPE STABILITY ANALYSIS OF EARTH DAM BY SLIP CIRCLE METHOD

SLOPE STABILITY ANALYSIS OF EARTHDAM:

Earth Dams are usually constructed using the locally available soil. The soil properties used for construction of earth dam are important in design of slopes. Civil engineers involved in design and construction of earth dams know the difficulty of design of slopes for stability of earth dams. I worked as Assistant Engineer in Design Circle in 1999 in Tamilnadu Public Works Department. At that time I saw many engineers involved in design of earth dams working on A0-size graph sheets drawing the cross section and draw a slip circle. Then they will create many vertical slices of Earth dam portion and calculate the area of slices below MWL/FRL/DDL of SPZ/IPZ and take the moments of weight of slices and resisting forces and put them in tabular form in the graph sheet itself to find the factor of safety as per IS Code(Indian Standard code). The area is calculated by counting the number of squares manually from the graph sheet. The notations above are
MWL- Maximum water level
FRL  - Full Reservoir Level
DDL – Draw Down Level
SPZ  - Semi Permeable Zone( Outer Zone of earth dam)
IPZ   - ImPermeable Zone(Inner Zone of earth dam)
spzblk- Bulk Density of Semi Pervious Zone soil
ipzblk- Bulk Density of Im Pervious Zone soil
spzsub- Submerged Density of Semipervious zone
ipzsub- Submerged Density of Impervious zone
spzsat- Saturated Density of Semipervious zone
ipzsat- Saturated Density of Impervious zone

usually 6 trials for upstream and 6 trials for downstream are done for arriving at the minimum factor of safety against failure. Roughly one month will be taken to do the 12 no of trials and factor of safety for the worst condition is found out. After seeing the laborious work involved in that process, I develop a program in AutoLisp to work in Autocad with one input table in Visual Basic for AutoCAD. This program made the design of slope stability in one minute in Autocad.

WEB DATABASE MADE SIMPLE

WEB DATABASE CONCEPTS
The concepts/secrets of database:
We are all using computer database in so many fields. In day-to-day life we use databases in internet banking, ticket reservation, bill payments, social network like facebook etc. The computer professional also mostly use SQL (Structured Query Language) for different databases like Oracle-SQL , MYSQL, MSSQL, POSTGRES-SQL. Almost all SQL have similar set of commands to Create, Insert, Update and Delete Records in tables of Databases. In initial periods of computer databases they use ^ delimited or any other special character delimited databases such as CSV(Comma Separated Values) format database tables. Even now CSV formatted databases are more compatible with Excel and other database tables. If we know the source program to Create, Insert, Update and Delete tables in SDF(Spike-^ Delimited Format) or CSV format, we can do a lot in the database field. The present stage of databases is developed by encrypting the SDF/CSV tables. In latest database by viewing the file contents, it is impossible to see the values for security reasons. The aim of this publication is to create awareness of simple database with SDF(Spike-^ Delimited Format) tables and how to do Create, Adddata, Query those tables. The source programs in VBSCRIPT in ASP/ASPX form and one Excel Sheet with macro for Exporting Excel sheet to SDF and Importing SDF into Excel Sheet is given localhost1.rar file. This can be downloaded from the following link.
http://www.nirt.in/software/localhost1.rar

This software is used to export any Excel tables into web database and make it query in all possible ways. The Software can be downloaded from the above link or link in the first page in the first page of manual given in the following link.

The unzipped localhost1.rar as webpage is available in the following link http://www.nirt.in/sampledb
You can test the software in the above link also.

Structural Analysis, Design and detailing for Reinforced Concrete Framed Structures within AutoCad Environment..

Structural Analysis, Design and detailing for Reinforced Concrete Framed Structures within AutoCad Environment..

I would like to introduce myself as the developer of this software and as well as a practicing structural engineer for past 30 years. I developed this software in AutoCAD environment  since, the most of the civil engineers and Architects are already exposed to it and is being adopted as the world leading design and drawing software. I started developing the this software from the year 1983, when I completed my graduation in civil engineering and my exposure to the AutoCAD was from 1987 when I did my post graduation at Coimbatore Institute of Technology, Coimbatore. Then I developed small software components in AutoCAD such as design of slabs, beams, columns and footings etc. with regular update as per my requirements. I never expected that adding all components with an effective interaction with AutoCAD will become this wonderful “CADMAX SOFTWARE” a boon for the practicing structural and civil engineers.

            Like other available structural analysis and design software, it contains no loose talks to show it high or less. It is not developed for International standards and is only for Indian standards as per IS-456-2000  and design aids. The wind load and earthquake load analysis are as per corresponding IS-code provisions. But the method and the speed of approach to get structural design and detailed drawings will be seen unimaginable while you are using this software when compared with other structural design software. It is not a large software to occupy a large portion of your hard disk and it will occupy nearly 10MB of space of your hard disk. But it will do the great job for practicing structural engineers which has been failed by other structural software. The terminology used in this software is so simple that any civil engineer/ Architect can easily understand and operate.

            This software is made into run with a pop-up menu in AutoCAD environment with the following main components:
1.Introduction of members such as columns, beams, slabs, walls and facia as drawing components in AutoCAD.

2.Calculation of beamloads from drawing entities automatically.

3.Introduction of wind load and earthquake components as drawing entities.

4.Analysis of the structure for dead loads, live loads, wind loads and earthquake loads as per requirements.

5.Design of members such as slabs, beams, columns and footings for critical forces of load combinations.

6.Reinforcement detailing of slabs, staircase, beams, columns and footings according to required type of gridlines with automatic grouping of members.

7.Preparation of detailed Design procedure for slabs, beams, columns and footings. 

8.Requirement of steel quantities for the structure stage by stage levels as required.

9.The calculation of all civil work quantites is under development and will be appended to this software very soon which will be very useful for preparation of estimates.

            I hope you will appreciate it, while using this software.

            Please do not hesitate to write your comments to me regarding upgradation as per your requirement.

            With best wishes,
