Environment management The link uses different sections & material databases, depending on the used Tekla Environment. These configurations are stored in the MidasEnvironmentStandards.cnv contained in the following folder: C:\<Tekla Structures installation folder>\<version>\nt\bin\plugins\tekla\link_ts_midas The typical paths are reported below: C:\Program Files\Tekla Structures\<Version>\nt\bin\plugins\Tekla\Link_TS_Midas C:\Tekla Structures\<Version>\nt\bin\plugins\Tekla\Link_TS_Midas The content of MidasEnvironmentStandards.cnv is reported in the next page. 4

This file is contained in the following folder: C:\<Tekla Structures installation folder>\<version>\nt\bin\plugins\tekla\link_ts_midas The typical paths are reported below: C:\Program Files\Tekla Structures\<Version>\nt\bin\plugins\Tekla\Link_TS_Midas C:\Tekla Structures\<Version>\nt\bin\plugins\Tekla\Link_TS_Midas A section of MidasSectionMapping.cnv file is reported below.

NB: If the link can t find a mapped section name, the link tries to transfer a parametric section compiling automatically the section parameters. Twin profiles Actually, the export of twin profiles from TS to Midas is partially supported by the link (see Cross section data table ). NB: To export Twin profiles, set Consider twin profile option to Enabled in Analysis Model Properties. If the option is set to Disabled [default value] Tekla Structures exports Twin Profiles as two single elements. The import of twin profiles in Tekla Structures is not supported. 5

Neutral axis The neutral axis is the analysis axis for all parts. The location of the analysis axis changes if the profile of the part changes. b. Reference axis The part reference line is the analysis axis for all parts. This option can t be used if there are truss elements in TS model. If the user ticks the Beam offset checkbox in the export phase, the section offset is set in one of the 9 permitted reference axis positions (cyan grips in the below image) accordingly to the reference line of the part. If the user doesn t tick Beam offset checkbox, the section offset is set in the centroid. If Neutral axis is selected, the user should not check the Beam offset option during the export phase. 7

8 Export from Tekla Structures to Midas Gen/Civil 1) In Analysis & design tab click on A&D models 2) Click on New button 3) Choose the settings that best suit to your case. We suggest to use the creation method By selected parts and loads and/or use a filter that excludes all the secondary elements and connections. 4) Choose the correct Analysis application: Midas 2017 Rel.A and eventually tick the Set as default option 5) Choose the proper Member axis location (for more details, please refer to Member axis location in the analysis model of Tekla Structures section) 8

9 6) Once clicked on OK button you should see the analysis model created according your settings. You can now check the correctness of the model. The user can modify the position of the analysis elements manually. 7) To export the analysis model, click the Export button 8) If there are no load combinations, the software will ask if you want to create load combinations. We suggest to answer No and create load combinations directly in Midas software. 9) By clicking on the OK button you re declaring that the analysis model you re exporting is in accordance with the physical model. 10) Choose the file format (Midas Gen or Midas Civil) and click on the Continue button 9

10 11) Select what needs to be managed by the link. By ticking 2D Elements, the link will export the perimeter of planar elements, including also holes inside them if holes are considered in the analysis model. The perimeter is exported with peculiar elements characterized by a. section number = b. section name = Contorno c. Profile: Round bar D=0.05mm Please consider that the 2D Elements tick will not affect panels whose Analysis member property class is equal to Wall Shear wall. These panels are transferred in Midas as wall elements. 12) Once created the MGT/MCT file, the link informs the user that the process was completed. 13) You can find the MGT file in <Model Folder>\Analysis\<Analysis model name> folder. 10

11 Import/export of MGT files in Midas Gen/Civil In Midas Gen you can import the MGT file exported by Tekla Structures (click on the Midas Gen Icon Import midas Gen MGT file). In the following picture you can find the import process result. Beam elements are colored in white, wall elements in light blue and plate elements in pink. You can see that for planar elements with openings and planar elements with more than 4 nodes only the perimeter is transferred. The user can easily select the perimeters and perform the mesh of the 2D elements. 11

12 In this example some changes are made in Midas Gen: a. A new floor is added b. The height of all the beams of the penultimate floor is increased from 600mm to 800mm c. The cross section of the column of the first two floors is increased from 400mm x 400mm to 500mm x 500mm To export the MGT file, click on the Midas Gen Icon Export midas Gen MGT file 12

13 Import in Tekla Structures of MGT file exported from Midas Gen/Civil 1) Overwrite the MGT file contained in the folder <Model Folder>\Analysis\<Analysis model name> with the MGT file received from the Structural Engineer. 2) Open Tekla Structures and activate the CTRL+5 view mode 3) In Analysis & design tab click on A&D models 4) Click on the proper Analysis model name and click on Import 5) Choose the File format and click on Continue button 6) Select what the link should manage in the import process and click on Continue button. Please consider that 2D plate elements cannot be imported in Tekla Structures. 13

14 7) Once the link has finished analyzing the MGT/MCT file, you ll see a window with info on New members, Profile changes, Warnings. Select the elements that you want to accept and click on Accept selection button. NB: Selecting an element in the Profile changes section will highlight the correspondent part in the model (see picture below). 8) After clicking on the Accept selection button you can close Analysis & Design Model window. You ll see that the model has updated the model with the latest accepted changes. 14

15 9) In order of looking at a glance what s changed, a new representation filter has been created: TS-Midas_status. This filter works on the TS-MIDAS_status UDA: New items are colored in green Modified items are colored in yellow Deleted items are colored in red Items not changed in Midas are colored in grey (70% transparency). 15
