Static calculation of pipes: Pipe statics for buried pipes

IngSoft EasyPipe trench installation concrete pipe

A 127 (Germany)

The calculation module A 127 follows the worksheet ATV-DVWK-A 127, 3rd edition (2000 version).

It provides the static calculation of underground pipes in trenches or embankment and allows the dimensioning of pipes made of all materials mentioned in the worksheet.

This module also determines trench widths in accordance with DIN EN 1610 and minimum dimensions according to DIN V 1201. It takes into account current concrete qualities and allows any custom materials. If required, it verifies buoyancy safety.

The calculation is performed automatically depending on the material and load for minimum and maximum groundwater levels or short- and long-term conditions. In the dynamic verification (fatigue), 2x106 and 1x108 load cycles are available as specifications according to A 127. In addition, the number of cycles can be configured as required. Reinforced concrete pipes can be designed with one or two layers of reinforcement.

On request, the cracking proof can be performed according to DIN EN 1992-1-1. The provided load package includes load model 1 (LM1) for road traffic, LM71 and UIC71 (railway) as well as reference aircraft. In addition it allows customised input (see also extension special vehicles) and the choice between SLW60, SLW30 and LKW12.

IngSoft EasyPipe trench installation GRP-pipe

M 45 (USA)

The 'American Water Works Association' (AWWA) published M 45 Fiberglass Pipe Design (2005 edition), a manual for underground installation of glass fibre reinforced plastic pipes (GRP-pipes), which has gained recognition in many parts of the world.

The module M 45 for IngSoft EasyPipe reproduces the static calculation of GRP-pipes (UP-GF-pipes) described in AWWA M 45.

As a user, you determine minimum and maximum cover heights and groundwater levels and specify backfill and bedding.

In addition, the programme accepts your information on the grown soil and the pipe geometry, which can be illustrated as a pressure pipe with PN/SN/DN or from a database.

The modulus of elasticity of the GRP pipe material, the position of the neutral fibre in the cross-section as well as loads (HS 20/25 truck, Cooper E-80 locomotive, internal pressure (as operating pressure, pressure surge, negative pressure)) must be specified.

IngSoft EasyPipe calculates deformation, strain and buckling pressure for pipes made of GRP.

SIA 190:2017 (Switzerland)

The SIA 190 calculation module follows the Swiss standard SIA 190, Canalisations, 2017 edition including technical documentation D0263.

It provides the static calculation of underground pipes in trenches or enbankments and allows the dimensioning of pipes made of all materials mentioned in the worksheet in flexible and rigid designs.

The Swiss regulations differentiate between pipes on ordinary, yielding or non-yielding ground.

Road, rail and field are available as load models.

The IngSoft EasyPipe software provides the following verifications:

  • Proof of stability
  • Stress verification
  • Proof of deformation
  • Buoyancy check

If the groundwater level is present, it must also be entered.

The new edition of the set of rules from 2017 - which is incomplete in the original - contains many innovations, which IngSoft EasyPipe provides in an independent calculation module.

In spring 2018, the SIA published the supplementary documentation D 0263 with the content Pipe statics - Technical documentation for the standard SIA 190:2017. The SIA offers the D 0263 for download with a fee.

  • The SIA 190:2017 calculation module is available. We obtain the results of the calculation examples with IngSoft EasyPipe.
  • Also available is the SIA 190 calculation module, which implements the 2000 edition of the regulations.
