RE Shoring Wall 2017 shoring design software

Examples: Overview


These examples cover the main features of RE Shoring Wall in a variety of real design scenarios.

Shoring projects often have specific design criteria that must be factored into the design. Design criteria may include:

  • Supports
    • Whether or not supports will be used.
    • Support Types: Internal, External or both.
    • Limiting maximum tieback lengths due to easements or obstructions.
    • Limiting tieback forces due to geotechnical restraints or instillation equipment that would be required.
    • Limited on tieback locations and angles due to obstructions behind the wall.
  • Material
    • Shoring installer may want to use existing materials they have on hand.
    • Lead time required for materials on a rush job may limit available materials.
    • Location. Availability of materials locally.
    • Cost of materials, we could do a chapter on this topic alone.
  • Shoring Duration
    • Duration may influence the choice of Embedment Calculation methods.
    • Duration may influence the choice of lagging and any rot treatment.
  • Embedment Depth
    • Geotechnical engineer may specify a minimum depth.
    • A rock strata may force a maximum depth.

General Instructions

The following information applies to all of the shoring design examples. If you are new to RE Shoring Wall, see Getting Started.


Each example begins with a few preliminary steps.

Preliminary Design

Each example begins with a preliminary design. The load cases to be included in the design are determined by which method of design is to be used, LRFD or ASD.

Sources of information:

  • Topographical Information: Use topographical maps or civil drawings of existing conditions to get existing elevations.
  • Project Plans: Obtain the finished elevations from the civil drawings of the finished project that are included in the project plans.
  • Geotechnical Report: Pressure diagrams, constraints, and recommendations.

A one page design template was used in these examples. The design template includes all the necessary information to input into RE Shoring Wall and record the results of each load case. Pressures are represented graphically, with the calculated values written in. The load cases to be run are entered into the table at the bottom of the design template. You are welcome to create your own design template for use in your shoring projects. The process for completing the design template is as follows:

  1. Enter Project Information into the fields at the top of template.
  2. Enter Geotechnical Parameters and Wall Design Parameters that are common to the entire project into the fields on the left side of template.
  3. Insert a CAD drawing of the wall section to be designed into the large open area. Drawing includes: Top and bottom of wall, supports, active pressures, passive pressure.
  4. Enter pressure values on the wall section drawing (drawing area).
  5. Enter the Load Case names and filenames in the table at the bottom of template (load case results are also recorded here).

Note: This design template was creating using AutoCAD, which permits drawing the wall drawing directly into the drawing area on the template. However, other programs such as Microsoft Excel can also be used to create a design template.

Preparing to Enter Data

Prior to entering data into RE Shoring Wall, click the File New toolbar button.

Basic Steps

The following steps are performed for each load case.

Step 1: Enter Data

  1. Launch RE Shoring Wall, or if already open, restore the Shoring Design Form to its default values by clicking the File New toolbar button.
  2. Enter project-specific data on the Project Information Form
  3. Enter design parameters in the Shoring Design Form:

Step 2: Run Load Case, Evaluate Results, Record Findings

  1. Run Shoring Analysis: Click the Run toolbar button. Menu and Toolbar
  2. Evaluate the results of the shoring run.
  3. If run successful and results are satisfactory, continue to next step. Otherwise, adjust input parameters as needed and do another shoring run.

Step 3: Record Findings

Record the findings for this load case on the design template.

Step 4: Save Input Values

You can save the data input into the Project Information and Shoring Design forms any time you like, e.g., before or after a run, any and all load cases, etc. A good rule of thumb is to save input values for any load case that has been completed/approved, or which is still under development.

Save Load Case Input Data: Click the Save toolbar button (or select Save As from the File menu), select/create a folder to save files for this example in, enter the File Name for this load case, and click OK.

Be sure to uniquely identify the files for each distinct section and load case by including the Section ID and Load Case in the file name, as in Figure 3.

File Naming Method #1: These examples use the naming convention <Location>_<LoadCase>, as seen in Figure 3. For Example, 1205+25_SERVICE-Ia (using road stationing for location) or S23_EXTREME (for the 23rd pile on the South wall).

File Naming Method #2: If you prefer to store input files from multiple projects/jobs in the same folder, use the naming convention <ProjectName>_<Location>_<LoadCase> to organize files by Project, Location, and Load Case, respectively, as in Figure 4.

Step 4: Print Reports

There are two ways to print reports:

  • Save reports after a shoring run and open/view/print them later in any Web Browser.
  • Re-open the input file from a prior load case, re-run it, and print reports.
