2. EXAMPLE 2: IMPORTING LATERAL LOADS TO AN ADAPT BUILDER MODEL

This example describes how to import lateral loads for level 2 into an ADAPT-Builder model. Models are already designed for gravity loads in ADAPT-Builder, however, the process requires checking the load combination that includes lateral loads. Geometry of a structure is as shown in Figure 2:

FIGURE 2

2.1 Crete An ETABS Output Files for Selected Story Level Only

1. Analyze model in ETABS.

The next step is to create output files. Since you want to import only the lateral loads solution for Level 2 there is no need to output information for all levels. To create ETABS output files that will include information you need to import level 2, you will have to select all components for level 2 and level 3 in ETABS. To do so follow the steps below:


14

2. In ETABS go to View->Set Building View Limits. In the Set Story Range select 3 for the Top Story and 2 for the Bottom story.

FIGURE 2.1-2

3. Select all components in the 3D window.

FIGURE 2.1-3

4. Go to File->Print Tables->Input.

5. In the above option, select the Check/Uncheck All button in the right lower corner of the Printed Input Tables window (see Fig. 2.1-4)


15

FIGURE 2.1-4


7. Select “Selection Only.”

8. Select “Print to File” and specify a file name and location where you want to save it.

9. Click OK. The ETABS program creates the file. In this example we will refer to this file as “LAKE SHORE TOWER_MODEL_geometry_level2.txt”

10. Select File/Print Tables…/Analysis Output.

FIGURE 2.1-5

11. Check all the items that are not grayed out (Fig.2.1-5)

12. Click the Select Loads tab and highlight the loads that you want to import.

13. Select “Selection Only.”

14. Select “Print to File” and specify a file name and location where you want to save the file.


16

15. Click OK. The ETABS program creates the file. In this example we will refer to this file as “LAKE SHORE TOWER_MODEL_lateralsolution_level2.txt.”

2.2 Create An INP File That Includes Only A Lateral Load Solution Using The ADAPT-Integration Console

This section describes how to create an input file (.INP) containing only lateral loads information for ADAPT-Builder using ETABS txt files.

16. Open ADAPT-IC console.

17. Click Next.

18. Check Import lateral loads and uncheck Import geometry and Import gravity loads.

19. In the Geometry Input File edit box upload the text file created in Step 9 “LAKE SHORE TOWER_MODEL_geometry_level2.txt”

20. In the Force Input File edit box upload the text file created in Step 15 “LAKE SHORE TOWER_MODEL_lateralsolution_level2.txt.” (Fig. 2.2-1)

FIGURE 2.2-1

21. Click Next. 22. From the list of all floor levels select 2 and click on the button

to move it to the List of selected floor levels. Note that this is the only level that you can import to Builder since you did not include information for other levels in the ETABS txt files.


17

FIGURE 2.2-2

23. Click Next.

24. Specify the name and location of the input file you will later import

into ADAPT-Builder. In this example we will refer to this file as “Lakeshore_level2.INP.” (Fig. 2.2-3)

FIGURE 2.2-3

25. Click Next. 26. The program shows a Summary report as shown below.


18

FIGURE 2.2-4

27. Click Finish. The program writes an INP file at the location you

specified in step 24.

2.3 Import of Lateral Loads To The ADAPT Builder Model

28. Open ADAPT-Builder file 2nd_16th_Floors_PT220.adm. This model is already designed for gravity loads. The reinforcement is as shown in Figure 2.3-1.

FIGURE 2.3-1

10-12mmx2000mm (T)


19

29. Go to File->Import->ETABS. 30. Specify the name and location of Lakeshore_level2.INP, the file that

you created in step 27, and click Open. 31. The program displays the Import Options dialog window. 32. Uncheck all structural components and select Keep original model as

shown in Figure2.3-2.

FIGURE 2.3-2

33. Select loads from the Static list as shown in Figure 2.3-3 and click on

the button to move them to ADAPT list.

FIGURE 2.3-3

34. Click OK.


20

35. The program imports geometry and gravity loads. For lateral loads the

program performs equilibrium and compatibility checks and shows the Lateral Loads Status Check table as shown in Figure 2.3-4. Since the Compatibility check is not performed at this point, some of the loads are not attached to columns or walls. To see these loads onscreen select Visible and click OK.

FIGURE 2.3-4

36. The program shows a report that lists all loads that do not act at the

top/bottom of the columns/walls (Fig. 2.3-5)

FIGURE 2.3-5

37. Close the report. The program displays forces on the screen. (Fig. 2.3-6).


21

38. To move column/wall forces in order to correct location do the following:

o Click the Select by Type, , tool. From the list that opens, select Point loads. Hold the CTRL key and uncheck story forces since these should not be moved (Fig. 2.3-6).

FIGURE 2.3-6

o Select the Move selection tool, , and enter the first and second point of the translation vector.

o In the Shift/Transform Lateral Loads dialog window select Shift lateral loads and click OK.

FIGURE 2.3-7

o The program moves loads to the new location (Fig 2.3-8)

FIGURE 2.3-8

o There are still some loads that fall outside slab region such as loads that fall above openings (Fig.2.3-9). You will have to fix these loads before importing. Select load and specify a translation vector to move


23

it to the location above near wall. Select the Transform lateral load option and click OK.

FIGURE 2.3-9

o Fix all loads that fall outside the slab region in similar manner (Fig 2.3-10).

FIGURE 2.3-10


24

39. When all loads are fixed click on the Exit “Lateral Load Editing”

Mode button. (Fig. 2.3-11).

FIGURE 2.3-11

40. The program asks if you would like to import lateral loads now. Click

Yes. (Fig.2.3-12)

FIGURE 2.3-12

41. Program checks equilibrium and compatibility of lateral loads and displays the Status check table again. (Fig.2.3-13). If all checks are OK, you can import loads to ADAPT-Builder.

FIGURE 2.3-13

42. Click OK. The program imports the lateral loads.

43. Now when lateral loads are imported they have to be included in load combinations (Fig. 2.3-14).


25

FIGURE 2.3-14

44. Analyze and design.

The reinforcement results are now as shown in Figure 2.3-15.

3. EXAMPLE 3: LATERAL LOAD DESIGN RESULTS IN ADAPT- BUILDER

This example shows moment diagrams and required reinforcement due to imported lateral loads. Lateral load cases are earthquake in X direction (EQX) and wind in Y direction (WINDY).

The geometry of a structure is shown in Figure 3.1.

FIGURE 3.1

Level 2 of the structure, including geometry and lateral load solution, is imported to ADAPT-Builder. Lateral load cases are included in load combinations. Structure is analyzed and designed for two load combinations:

1*LATERAL_EQX 1*LATERAL_WINDY

Builder column forces and unbalanced moment to the slab are compared with ETABS solution.


27

Results obtained for EQX:

ETABS column forces due to EQX load matches with Builder column forces. The same amount of unbalanced moment is transferred to slab (Fig. 3.2).

Total amount of unbalanced moment that is transferred to the slab, at location of the example column C12, is 248.51+84.63 = 333.14 K-ft

FIGURE 3.2 In ADAPT-Builder moment diagrams due to EQX are as shown in Figure 3.3:

FIGURE 3.3

A detailed Moment diagram for Support line 3 is shown Figure 3.4. The total amount of unbalanced moment at the location of example column C12 is:

157.27 +152.55 = 309.82 K-ft (ETABS 333.14 K-ft)

Note that the forces in ADAPT-Builder are reported for the section at the face of the column, not at the column centerline where load is applied.

FIGURE 3.4


30

Required reinforcement is as shown in Figure 3.5:

FIGURE 3.5

Results obtained for WINDY:

ETABS column forces due to WINDY load match with Builder column forces. The same amount of unbalanced moment is transferred to slab (Fig. 3.6).

Total amount of unbalanced moment that is transferred to the slab at location of example column C12, is:

182.33+11.01 = 193.34 K-ft

FIGURE 3.6


32

In ADAPT-Builder moment diagrams due to WINDY are as shown in Figure 3.7:

FIGURE 3.7

A detailed Moment diagram for Support line 11 is shown Figure 3.8. The total amount of unbalanced moment at the face of the column C12 is:

7.76 + 87.71 = 175.43 K-ft (ETABS 193.34 K-ft).

The difference is due to the fact that the forces in Builder are reported for the section at the face of the column and not at the column centerline where the load is applied.
