Calculation of interest |
|
![]() |
This app calculates the tables, which are included in the guidelines of the LAWA-working committee for the realisation of dynamic cost comparison calculations. |
Depreciation |
|
![]() |
This app determines the depreciation rates for constructions. The rates can be calculated on a linear, declining or annual basis. |
Estimation of the subsidence above the shield machine |
|
![]() |
This app for the estimation of the subsidence through at ground level in cross direction during shield tunnelling, enables the user to determine the estimated depth of the subsidence and also the estimated subsidence at any distance from the jacking axis. The estimations can be carried out according to the approaches of O'Reilly and New and the critical angle ß-theory. |
E-Modulus pressure transfer ring |
|
![]() |
This app serves for the calculation of the elastic modulus of pressure transfer rings in jacking measures. |
Formula PRO |
|
![]() |
To support your daily work the Tool "Formula PRO" comes with a broad and concise formulary. The current version of "Formula PRO" offers calculation of geometrical parameters of different 2-dimensional and 3-dimensional figures as well as hydraulic parameters of pipe- and channel profiles. |
Gaussian calculation of areas |
|
![]() |
This app serves to calculate the total area of arbitrarily shaped and closed survey traverses. |
Hydraulic charts |
|
![]() |
This app determines the maximum flow rates (Qmax) and the flow velocity (v) of selected sewer profiles. |
Invert shear stress |
|
![]() |
This app calculates possible invert shear stresses in circular cross sections. |
Jet pressure in high pressure water jetting |
|
![]() |
This app calculates the effective jet pressure of a cleaning nozzle in high pressure water jetting |
Quantity converter |
|
![]() |
This apps converts the given values into the required quantity. Please choose quantity range, confirm your selection if required (for deactivated JavaScript) and enter at least one value that is to converted. |
Section forces of circular pipes |
|
![]() |
This app calculates the cutting forces in the reinforced concrete circular pipe depending on the bedding angle a. The rectangularly spread load has any broadness and the bedding backpressure is evenly radially spread |
STATUS Flow |
|
![]() |
This app serves for calculation of hydraulic characteristics of any cross section |
