Excavations Braced with Struts in DeepEX
Braced excavations can be designed with DeepEX software in the most efficient way. In DeepEX, we can design excavations braced with steel struts and rakers in 3 simple steps:
1. Create our model in minutes in the software graphical interface, or using the powerfull model wizard (all construction stages).
2. Define the strut or raker support type, structural section and spacing.
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 Support Sections and Spacing
Defining the Support Elevation and Spacing
At any time, we can access and edit the strut elevation on the wall, support spacing and the unbraced lengths. DeepEX can distribute the surcharges on each support and perform all structural checks according to the selected structural design standard.
Defining the Strut Structural Section
In DeepEX we can define the steel section type for our struts, using pipes, H beam or rectangular hollow pile sections. The user can select any of the available steel sections from our extensive implemented databases, or define the steel section properties manually.
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.
