Software for the Structural Calculation of Buried Pipes

2 Product Information IngSoft EasyPipe

Benefits of the structural calculation of buried pipes Structural calculations help

• to ensure a solid structure regardless of any possible load combination

• to save material and to make an economic design.

While the need of structural calculations for buildings above ground level or tunnels is widely accepted, buried pipes and manholes are not always designed based on static aspects. A lack of structural calculations will often result in major fol-low-up costs in the event of claims, but even more often this will cause overdimensioned constructions and unnecessary expenses.

Benefits for the client

It is in the interest of all clients to insist on individual calcula-tions for the pipes and manholes already during tendering. It is advisable to verify the presented calculations by them-selves or to assign this task to a third party. Reliable struc-tural calculations in accordance with valid standards can prevent follow-up costs, potential conflicts and legal claims in case of damage.

Benefits for the planning engineer

Structural design bureaus are usually involved in pipeline and manhole installations. Way too many designers rely on the manufacturers of pipes and manholes to provide the required structural calculation.

However, only the own structural calculation during the planning phase shows

• which fundamental factors influence the stability of the components

• where the manufacturer has made convenient assump-tions in the calculation

• which of the assumed parameters must be considered in order to assure the validity of the provided structural cal-culation.

• Furthermore, an objective and individual comparison of the advantages and disadvantages of certain materials (plastics, concrete etc.) can only be made considering structural aspects.

Benefits for the pipe and manhole manufacturers

Given the hard competition, it is in the interest of the manu-facturers not to offer overdimensioned components. The structural calculation provides an additional documentation, legal security and transparency.


Software for the structural calcula-tion of buried pipes Since 1997 IngSoft develops software to assist engineers and manufacturers with their structural calculations of buried pipes and manholes.

The increasing complexity of standards which must be con-sidered, asks for high-performance software solutions which also lead to economic advantages.

As a professional software developer, IngSoft puts particular emphasis on user-friendliness and a flawless integration into modern IT landscape. By following current Microsoft Win-dows standards it is ensured, that the software can be in-stalled and maintained with low effort.

Although the use of the software is fairly easy to learn, the software addresses professionals with adequate knowledge of the static background.

Software for buried pipe lines

• IngSoft EasyPipe combines a variety of calculation methods in accordance with national (e.g. ATV-DVWK-A 127, DWA-A 161) and international (e.g. SIA V190, AWWA M 45) standards. IngSoft EasyPipe allows calcu-lation of jacking pipes and pipes installed in trenches un-der consideration of various materials.

• Also the structural calculation for the rehabilitation of drains and sewers by lining and assembly methods ac-cording to DWA-M 127-2 (liner/inliner) is possible. Landfill pipes and boxes for seepage water – in particular made of plastic – can be calculated with stand-alone programs.

• Special forms: As a competent partner, IngSoft GmbH supports you in the calculation of rare, complex forms such as taper cross-section, kite-shaped cross section or channels with dry weather flow. Please contact us for further assistance. You will find the contact information on the back of the brochure.

Product Information IngSoft EasyPipe 5

Enterprise edition

The enterprise edition corresponds to the professional edition with additional features:

• pdf files can be defined as obligatory attachments. For instance, it is possible to generate only certain pdf files that contain the company’s general terms and conditions. Such attachments can be defined separately for each lan-guage.

• wording of text templates, which are included as a gen-eral note on the front page

It is particularly suitable to assure consistent quality stanards.

All editions are complemented by calculation modules that comply with standards. Further extensions and additional functions are available upon request.

Modular structure Different calculation modules are available. Each of these representing a national or international standard. Language modules make the international use of the software possible.

Figure 5: Several statics within one project (Professional edition)

Ground water levels are taken into account accurately. The crack width verification for reinforced concrete pipes can be conducted additionally. Time-dependent behavior of different synthetic materials is traceably represented in two separate calculation courses.

Calculation module A 127

The calculation module A 127 based on the ATV-DVWK standard A 127, 3rd edition, published in August 2000 is suitable for the structural calculation of buried pipes installed in trenches and banks. It allows the buried pipes calculation of all materials mentioned in this standard.

Partially, the calculation module exceeds the range of the standard. For instance, the trench width is checked according to DIN EN 1610 and the minimal dimension determined ac-cording to DIN V 1201. A consideration of different concrete qualities is possible, steel qualities of RiL 877 are deposited.

Calculation module A 127 extension: circle/egg-shaped pipe profiles with base

As an expansion of the calculation module A 127, circular profiles (KFW according to DIN 4032) and egg-shaped profiles (EF according to DIN 4032) with base can be calculated. Thereby the moments and the normal forces are taken from the publication ‘Structural Analysis of Buried Pipes’ by Hor-nung/Kittel, 1989.

Calculation module A 161

Jacking pipes can be structurally designed using the calcula-tion module A 161, which is based on the 2nd edition of the DWA-A 161 standard. This is the first DWA standard which contains regulations for the structural calculation of pipes with partial safety coefficients according to the relevant DIN standards. This semi-probabilistic concept has its origin in the Eurocodes and it is inherited from the calculation module.

Calculation module M127-2 / A 143-2

In cooperation with S&P Consult a module for the DWA-M 127-2 and its successor DWA-A143-2 has been developed wich provides the verification for the host pipe conditions I – III by means of the finite elements method (FEM).

Thereby the liner can be statically dimensioned in rehabilita-tional purpose.

Figure 6: Input and result preview

The host pipe condition III calculates automatically all necessary load case combinations.


Figure 7: Moment diagram output (section)

The DWA-A 143-2 module is currently a blueprint. A final version based on the blueprint is scheduled for spring 2013.

Calculation module M 45

The M 45 ‘Fiberglass pipe design’ published by the American Water Works Association (AWWA) is a manual for the buried pipes design, accepted in many parts of the world. The struc-tural calculation of fiber glass pipes described in M 45 (edition 2005) is represented in the calculation module M 45.

Further calculation modules

• Fascicule 70

• SIA 190 for flexible pipes (it is planned to include rigid pipes at the end of 2013)

• Manholes (planed for 2013)

Languages

By licensing additional language modules it is possible to change the language of the user interface and to generate printouts in other languages. For instance it is possible to use an german user interface for entering the inputs but to print the results in polish.

Language is immediately available Language is available on request (a surcharge might

apply)

Further languages are available on request.

A purchased language module expands all calculation mod-ules of an existing license if the translation is available. This also applies for additionally acquired calculation modules.

Extensions

Calculation modules can be extended by specific functions on request. These extensions are available for all acquired mod-ules.

On the following page the extensions ‘Load editor’ and ‘Pro-file values from sketch’ are introduced.

IngSoft will gladly develop specific extention features accord-ing to your needs. Please contact us for further assistance. You will find the contact information on the back of this brochure.

Load editor

To represent special vehicles, non-existent in current regula-tions, IngSoft offers the expansion ‘Load editor’. Using the ‘Load editor’, the pressure under stackers, reach-stackers or airplanes such as Airbus A 380 can be determined.

Figure 8: Extension ‚Load editor‘

The approach is based on pyramidal load spreading. The load spreading angle in soil, as well as possibly another load spreading angle in a different layer (road structure) are to be entered by the user.

Any given distances between axes, wheel compositions and wheel loads can be entered.

Regardless of current earth coverage, the load course can be output as a separate pdf file. The output is carried out in graphical and table form.

Profile values from sketch

This extension allows the calculation of cross-sections from drawings of profiled pipes.

Figure 9: Extension ‚Profile values from sketch‘

The picture file has to be processed as a black and white bitmap file (.bmp extension). Only the exact black areas are recognized and assigned to the profile after loading the file in IngSoft EasyPipe.

The computed profile values can be regardlessly output of any current calculation as a pdf file.
