The copy protection is managed by a program, CMNET, which must be downloaded and installed on a server, or any station on the network. After a purchase is made via Paypal, Pile Buck will send a separate email with a key code to unlock the program. No refunds after purchase. Upgrade rate is acceptable for users running version 2. For users running an older version, you will need the full program, but your cost will be discounted.
Must have a license key to upgrade. Please call for upgrades. SPW v2. To unlock the program, use the key code provided in the email from Pile Buck after purchase. Twenty The options between braces and walers is really for presentation purposes; it informs the installer what kit is being installed.
Changes in soil parameters, water tables, etc sometimes produce no change in the calculated net pressure. This is probably due to the presence of soils with a high cohesion. In such cases, the calculated soil pressure may be negative, and the pressure values are being calculated using the minimum equivalent fluid pressure, MEFP. You can change units in the Setup page of the define box. The best time to do this is when you first open a job. Doing so later can create problems with the database; the only way to deal with it then is to reinstall the program.
If you work consistently in U. You can then proceed to enter the rest of the job information. If you do have to reinstall the program and have made entries to the database, you can do the following:.
Only uniform surcharges can be input into the program. The program does not consider point loads, strip loads, etc. No, the datum is fixed at ground level. To change this would interfere with the calculation methods of the program. Thus, the difference between the two shear values immediately on either side of the support will equal the magnitude of the support load.
The soil K values have probably been modified inadvertently. Check the K values before and after the changes — they must be the same if the same results are to be found. For example, load Demo2 and note P, waler load, toe, etc. Open the Excavation page, and select a 20 degree slope — P, etc all change.
Now select level ground again — they change again, but do not go back to what they were. This happens because the K values are recalculated to their theoretical values, based on phi, when slope or level ground is selected. Similar things can happen when the pressure model is changed. If the pressure appears to have changed, then check the K values at each depth. Email us if this does not solve the problem. The 25 ksi value was placed for conservatism. You can change this value in the database for each individual section.
The soil coefficients are changed when you switch from Rankine to Coulomb and back again. Each time you switch, the K values revert to their theoretical values under the selected model. The pile length used when you switch back to Rankine is because a different pressure is being calculated due to the changed soil coefficients. Your computer should be set to Small Fonts when using SPW, or some tabular output will extend beyond the right edge of the window or overlap.
To reset your computer to small fonts:. Your company logo or other information may be displayed in the area at the left side of the title bar below the main design area. To use this area, create a bitmap file called MyLogo, and save it in the Data folder of the install directory directory. The bitmap will be plotted in the appropriate area. The bitmap may be any size as it is scaled to fit the space available. However, as the maximum display area provided is pixels x 70 pixels, the bitmap used should not be much larger than this.
Your company address and other contact details can be displayed in the title bar below a design. They can be altered in the Setup page of the define box.
Double click anywhere on a design and select the Setup tab for this page. Alternatively, double click the relevant hotspot to open the define box at the Setup page. Please email Pile Buck with details of the printer, etc if the problem persists. If there are no other Borland products, or one s that he will not be using simultaneously with SPW, it should be OK to proceed with the install. If this is not the case, and there are other Borland products, locate the following files on your hard drive: USA.
It should be noted that none of this may be necessary. It is entirely possible that SPW will work properly if the program installation is completed. These problems mainly in Windows and Me; probably in XP also are due to changes in Windows that Microsoft has made.
We have a fix for these problems and if you would like it click here and email us with your request. In some cases, color printers will still have problems, in which case turn the color graphics off in the Setup page.
It is especially helpful when revisions take place; the documentation can be changed and updated much more readily. As far as the methodology is concerned, the methods used in SPW are described in the British Steel Piling Handbook 7th Edition , which can be viewed at corusconstruction.
As is very common with foundation design, there are many variations on design methods for the various types of structures and this is certainly true with sheet piling. It is not practical to include all of them in one computer program. If you can obtain these, this type of error message may be eliminated. A check is also made on soil densities, and a warning is displayed if a submerged density seems large compared with the bulk density.
Other checks will be added as they are identified. These can improve design safety. With cantilever walls, safety factors can be dealt with in several ways. One of these is to divide the passive earth pressure coefficients by a reduction factors typically 1. The other way is to compute the equilibrium condition for summation of forces and then add toe length.
SPW uses the latter approach. If you want to reduce the passive earth pressure coefficient, you can do so directly in the soils page. User can enter a toe including 0 manually. In all cases, FOS can be calculated and displayed. To change the factor of safety:. Different active and passive pressure coefficients are used for the Rankine and Coulomb models. The net pressure is calculated by finding the sum of the active and passive earth and water pressures:. This is the default in SPW, but the value may be changed in the Excavation page of the define box.
Additional loading due to vehicle movement, foundations, etc can be modelled by increasing the standard surcharge. Water pressure is then calculated within each soil layer.
SPW is a very effective and intuitive tool that will greatly reduce the time spent on manually making calculations. You can purchase SPW software here.

Volume 36 Issue 2. Volume 36 Issue 1. January 31, Getting Started After starting the program, the user needs to agree to the disclaimer and license agreement. Create a mock or test file to get started. If the properties of the desired sheet pile are not in the database, it is very easy to input them.
The user can enter the properties of various sheet pile materials — steel, vinyl, FRP composite, aluminum, concrete, timber, or combinations. Any number of soil types can be added along with their associated design strengths. Even special soil layers can be created to facilitate the analysis of flood walls and walls backfilled with concrete.
This is a powerful feature, allowing the user to evaluate fluctuating water levels and their impact on the sheet pile structure with just a few clicks. Also in this section one can specify varying ground slope s in front and behind the sheet pile wall to evaluate changing cross section geometry s. Pick an existing soil name from the soil database or enter each parameter individually.
Repeat this process until all required soil layers have been inputted. Here, the modeler can pick the sheet pile from the database or else enter sheet pile properties individually. Again, it is much easier to select a sheet pile from the database.
When the FESM is selected, the program uses a default factor of safety of 2 for an anchored wall and a default factor of safety of 1 for a cantilever wall. This is not to be confused with a material factor of safety for overstressing the sheet pile.
The Fixed Earth support method provides for slightly greater penetrations to generate greater passive resistance and reduce loading in sheet piles and anchors and provides for greater factors of safety as it relates to sheet pile penetration depth.
Soil factors of safety can be selected and applied to the passive side water side of the sheet.
