A-Frame Excavations - Design with DeepEX

A-Frame Systems in DeepEX

A- Frame deadman wall systems can be designed with DeepEX software in the most efficient way. In DeepEX, we can design and optimize A-Frame systems in 3 simple steps:

1. Create the excavation model in minutes in the software graphical interface, or using the powerfull model wizard (all construction stages).

2. Define the ground anchor positions, lengths and structural sections.

3. Run the analysis, review the results in each stage and optimize the model (manually or with the use of the DeepEX autimatic optimization tools).

The following paragraphs present how we can follow these steps within the software and achieve an efficient model optimization in minutes.

Step 1: Create the Model (All Construction Stages)

In DeepEX we can graphically add construction stages and draw the model on the model area stage by stage, or use the model wizard to create a model with all construction stages in seconds. Either way, we need to create a detailed staging, starting from at rest conditions in an initial stage, and then step by step generate new stages with each excabation and support installation level. DeepEX will analyze and present results for each stage, allowing us to review the full model construction process, identify the most critical stage and optimize our structural sections and support locations in the most efficient way.

Step 2: Define the Tierod Elevations and Structural Section

Tierod Elevation and Spacing

At any time, we can access and edit the tierods on the model area, or through the related tab of the model wizard. There, we can define the anchor elevations on the wall, as well as, the tierod spacing.

Defining the Anchor Structural Sections

In the Anchor Sections dialog of the program we can create a list of anchor structural sections to be used in the model. For each anchor section we can define the section type (strands or hollow bars, solid rebars etc.). We can also define the number of strands and rebars, as well as, the rebar or strand materials and the diameter of the tieback grouted zone. The software implements a database with several anchor sections that can imported and used in any software file.

Step 3: Review the Results and Optimize the Model

DeepEX can analyze any deep excavation model with several implemented analysis methods (classical Limit Equilibrium, Non-Linear Analysis with elastoplastic springs and Finite Element Analysis). After the analysis is completed, DeepEX software presents all calculation results in tables and in graphs on the model area for each construction stage. We can review all calculated stresses, moment and shear diagrams along with the structural capacities, the support and wall check structural ratios, the wall embedment safety factors and more. This way, we can have a great overview of all structural items designed by the program for each stage, and take important decisions for the efficient model optimization.

We can optimize any model fast either manually by accessing all wall and supports on the model area and edit the structural sections and support locations fast through user friendly dialogs, or use the software automatic optimization tools that can fast check and give us a variety of section solutions for all structural items on the examined model.
