DeepEX - Shoring Design Software: Automatic Model Optimization Tools
Introduction - Model Optimization
DeepEX produces and shows all analysis and design results for all structural items in tables and graphically on the model area in a very comprehensive way. The results are presented for each construction stage, and related failure notifications are provided to the user, allowing the effective model review and the efficient modification and optimization of all structural elements.
The user can rigorously compare different design alternatives and take important decisions by evaluating the produced results. The software also provides a series of automatic optimization tools, effectively assisting the user in the optimization of the wall and support structural sections, the support locations, the fixed length of the ground anchors, the wall embedment length and much more. Most automatic optimization tools can be accessed from the "Optimize" tab of the program, after the analysis is performed.
Automatic Optimization of a Design Section (All Walls and Supports)
The “Optimize Design Section” option in the Optimize tab of DeepEX will start optimizing automatically all structural members (walls and supports), if the calculated structural check ratios ("Force" or "Reaction" / "Structural Capacity") are above the limit “1”.
Walls:
For each wall in the selected design section, the software will check and report different structural sections of the selected wall reinforcement type (H piles, pipes, channel sections, sheet piles or rebar configurations by using the software implemented steel sections and rebar sizes databases), along with the calculated structural ratios. We can select from the provided list with sections and ratios which section should be applied in each wall.

Supports (Ground Anchors):
For ground anchors structural optimization, the software will optimize the number of strands using the specified strand diameter, so that the produced structural capacity is bigger than the applied support reaction. DeepEX will repeat the procedure for each ground anchor and notify us about the section change.
For ground anchors geotechnical optimization, the software will start increasing the anchor bonded length by the value DL that can be edited by the user, calculate the geotechnical ratio for each step and stop the analysis when the calculated geotechnical capacity is more than enough to cover the applied load, or the limit length in the Redesign options dialog is reached.
Supports (Struts, Rakers, Slabs):
For each support (struts, concrete slabs, rakers) in the selected design section, the software will check and report different structural sections of the selected support reinforcement type (H piles, pipes, square hollow sections or rebar configurations by using the software implemented steel sections and rebar sizes databases), along with the calculated structural ratios. We can select from the provided list with sections and ratios which section should be applied in each support.

After optimizing each support and wall in the selected design section, DeepEX will load a file listing all the changes performed by the software on structural sections and anchor lengths.

Automatic Optimization of Support Locations
The “Optimize Support Locations” option in the Optimize tab of DeepEX allows the program to evaluate different support elevations and optimize the location. In the dialog that appears, we can specify the initial and maximum depth for each support, as well as, the depth increment which the software will use to move each support and the maximum desired wall displacement. DeepEX will start a long-lasting procedure, where it will use all possible combinations for each support on the model area using the defined limits and depth increment, it will perform the analysis for each combination and return the position combination that produces the optimum wall moments and displacement diagrams.

Automatic Optimization of a Single Support (Structural)
The “Autodesign a support (STR)” option in the Optimize tab of the program allows us to select a support on the model area and perform structural section optimization of the selected support. For a ground anchors structural optimization, the software will optimize the number of strands using the specified strand diameter, so that the produced structural capacity is greater than the applied support reaction. For struts, concrete slabs or rakers, the software will check and report different structural sections of the selected support reinforcement type (H piles, pipes, square hollow sections or rebar configurations by using the software implemented steel sections and rebar sizes databases), along with the calculated structural ratios. We can select from the provided list with sections and ratios which section should be applied to the selected support.
Automatic Optimization of a Single Wall (Structural)
The “Autodesign a wall (STR)” option in the Optimize tan of the program allows us to select a wall on the model area and perform optimization of the structural section of the selected wall. The software will check and report different structural sections of the selected wall reinforcement type (H piles, pipes, channel sections, sheet piles or rebar configurations by using the software implemented steel sections and rebar sizes databases), along with the calculated structural ratios. We can select from the provided list with sections and ratios which section should be applied in each wall.
Automatic Optimization of a Single Ground Anchor Fixed Length (Geotechnical)
The “Autodesign fixed length for a ground anchor (GEO)” option in the Optimize tab of DeepEX allows us to select a specific tieback in the model area and optimize the fixed length. The software will start increasing the anchor bonded length by the value DL that can be edited by the user in the Redesign options dialog, calculate the geotechnical ratio for each step and stop the analysis when the calculated geotechnical capacity is more than enough to cover the applied load, or the limit length in the Redesign options dialog is reached.
Automatic Wall Depth Optimization (LEM Analysis Only)
When the Limit Equilibrium Analysis Method (LEM) is selected, the option “Optimize wall embedment for safety factors” appears in the Design tab of DeepEX. By selecting this option, we can define the required safety factors for the cantilever stage and the stages with supports, as well as, the increment DL that will be used for the wall embedment optimization. The software will start increasing the wall depth from the excavation depth using the defined increment and calculate all wall embedment safety factors (passive, rotational and length) for each step. DeepEX will stop the analysis at the point where all calculated factors are above the defined limits and return that depth.
