sazeh workflow
This page shows the steps from uploading the file to receiving the sheet, and what you must specify at each step. See the overview for a general introduction.
1. Prepare the model file
The input is an .e2k file exported from ETABS itself; ETABS does not need to be installed on your machine. Before you export from ETABS, check the following:
- the model must have dead load, live load and the earthquake load of the model, and the material of every member must be defined;
- if the model has shear walls, define a pier label for each wall so that the wall force can be attached to it;
- the size of the file must not exceed the upload limit of the site (currently 20 MB).
2. Upload the file on the home page
On the home page, choose the file and specify the following:
| Item | Description |
|---|---|
| Design base acceleration A | Choose one of the four values: 0.20 (low hazard), 0.25 (moderate), 0.30 (high) or 0.35 (very high), as the seismic hazard of the site requires. |
| Soil type | Type I to IV, according to the geotechnical report of the project. |
| Structural system | Intermediate or special reinforced-concrete moment frame, dual system of frame and shear wall, intermediate or special steel moment frame, or braced frame. The coefficients of table 3-4 come from this choice. |
| Penthouse | If the top storey of the model is a penthouse, declare it. sazeh does not guess a penthouse. |
| Compatibility torsion | If the torsion of the beams is of the compatibility type, tick this option. The assumption applies only to the corrected model; the original model stays as uploaded. |

3. Wait until the check is complete
sazeh reads the model, builds the code loads, analyses the building and checks every member. The time depends on the size of the model and ranges from a few minutes to a few hours for large buildings with walls. The job page shows the status, and the page does not need to stay open.
4. Read the result
- The original model. The 3D view of the building as you uploaded it, with the status of each member and the list of clauses that are not met.
- The calculation sheet. An A4 report, currently in Persian, that starts with the result and contains the assumptions that change the answer, the design coverage, the support reactions and the quantities.
- The corrected model. If a clause is not met and a change of section can fix it, a model with corrected sections is built and checked again. The section groups that changed are listed with the weight of each group.
5. Apply the corrections in ETABS
The closing section of the sheet turns the corrections into actions that are named after ETABS windows. sazeh does not change your ETABS file; the engineer applies the corrections in the model and, if needed, uploads the new file again.
An important note about the result
A clause that cannot be fixed by a change of section, for example a modelling question or an assumption of the engineer, is listed in the sheet with what would close it. A "deferred" row means that the item cannot be checked with the present tool and its verdict rests with the engineer. The responsibility for the result and for the signature rests with the engineer (limitations).
