1. OVERVIEW

This document explains the contents and functions of the standalone integration console which can be used to generate the ADAPT input file (.INP file) using data from modeling programs such as ETABS and ROBOT Millennium.

The purpose of this console is to generate an adequate file for import to ADAPT-Builder.

Based on user selection this file may contain geometry, loads or lateral loads information for different levels of a structure. The integration console performs various checks depending on which third-party program is the basis for generating the input file. For example, if the user selects to import lateral loads from ETABS, the integration console will perform an equilibrium check and a wall pier label check to verify that the data reported by the third-party program and imported to Builder program is valid.

This integration console is a four-step wizard.

1.1 ETABS INTEGRATION

1.1.1 Create INP Input File for ADAPT-Builder

Step 1

Start the integration console. Currently, you can only use the program to generate an input file from an ETABS model. (Fig.1.1-1).

Click on the “Next” button. Dialog of Figure 1.1-2 appears.

Step 2

Select all or some of the import options. Based on your choices you will be required to browse for the adequate input files from ETABS. If you only select to import geometry with or without gravity loads, you only need to provide the path to the geometry input file.

Enter the required paths of the input files (files generated from ETABS) in the dialog window displayed in Figure 1.1-2. Insert the path of the geometry input file and the force input file using the Browse option. The Geometry Input file and the Force Input file are the two text files generated from ETABS. Press the “Next” button to go to the next step or “Cancel” to cancel the entries.

If the format of the Geometry or Force Input file is not adequate, the program will prompt an error message. For example, if you select to import Gravity or Lateral loads that are not defined as static load cases in the ETABS file the program will prompt a warning message.

Step 3

In this step you specify the levels you want to import to ADAPT -Floor pro.

• Make a selection from the list of available ETABS levels

• Click the button to move them to the List of selected floor levels.

If no level is selected and you hit Next, an error message will show up.

Step 4

In this step, specify the name and location of the input file you will later import into ADAPT-Builder. You can either browse to the target location of the input file or simply enter the path and name of your input file in the text field.

The program performs equilibrium checks for all selected levels from the list and writes valid loads to the INP file. Equilibrium checks are performed per level for each load case. The INP file will include only those levels for which all lateral load cases passed equilibrium check. During this step a wall pier label check is also performed. The purpose of this check is to find out if all walls have a pier label assigned.

After equilibrium check is completed the program will generate a Summary report as shown in Figure 1.1-5. For each level the program will show if the equilibrium check passed or failed. To view result details of a level, highlight the level and click Details. The equilibrium check report will display.

FIGURE 1.1- 5

If the equilibrium check is satisfied, the program reports the sum of forces in X, Y and Z.

FIGURE 1.1-6

If the equilibrium check is not satisfied, the program displays a deviation in equilibrium (%) and marks it in red (Fig. 1.1-7)

FIGURE 1.1-7

The program also identifies potential issues with the ETABS model and displays those issues in the Summary report. At this time the program checks if pier labels are assigned to all walls in ETABS. For example, if equilibrium is found to be inadequate for level STORY1 and there are pier labels missing for that level the program will report the following:

“Level STORY1 equilibrium check failed. Pier label check failed.”

INTEGRATION CONSOLE Chapter 1

The details will show which wall does not have a correct pier label (Fig.1.1-8)

FIGURE 1.1-8

Note that pier label omission is only one of the possible reasons why equilibrium is not satisfied. If you fix pier labels in your ETABS model the equilibrium check might still not be satisfied due to other reasons.

If the equilibrium check is not satisfied and the actual error rate is not more than 10% you have the option to increase acceptable percentage of error to satisfy equilibrium check. To do so, click on the Increase tolerance button. The dialog window shown in Figure 1.1-9 will open. Change the tolerance and click Continue. The program will recheck the levels that did not satisfy the equilibrium check and show a new Summary report with an updated status.

FIGURE 1.1-9

If you click on Finish on the Summary report window (Fig. 1.1-7), all levels for which the equilibrium check is passed are written to the input file specified in step 4 (Fig.1.1- 4).

1.1.2 Import to ADAPT-Builder

Open ADAPT-Builder and go to File -> Import -> ETABS. Once located the Import Options dialog window shown in Figure 1.1-9 is displayed. You can select for the level you want to import, as well as components, loads, load cases and load combinations. If the Builder file you are about to import into already contains a model and you select the Keep original model option, the items you select in the three tabs will be added to the existing model. If the option is not selected, an existing model would get erased and the selected items are imported.

FIGURE 1.1-9

In Builder, the following checks are executed when importing a level which originates from an ETABS model:

1.1.3 Create ETABS txt Files for Import to ADAPT-Integration Console

Using a numerical example, this Section describes in detail the procedure for creating txt files from ETABS.

ETABS generates two types of data files. One contains the geometry and gravity loading and the other contains the information on lateral forces. ADAPT-Integration console uses both of these files to extract the information it needs and creates an input file for ADAPT-Builder

Figure 1.1-10 shows the geometry of the three-floor building used for illustration of the import procedure. The building has a square floor plan, with one shear wall on each side. The loads acting on the structure are:

Uniformly distributed dead load on each floor; Earthquake in X-direction; and, Earthquake in Y direction.

FIGURE 1.1-10 GEOMETRY OF THE STRUCTURE

Note when you prepare your input data for ETABS, you should observe the following:

Builder only imports loads that are assigned “STATIC” condition in ETABS. Non-STATIC loads are generally not valid for combination with gravity design of floor systems.

If your model has intersecting walls, do not use grouping into one pier. Use each wall panel as a separate pier.

Do not assign pier label to columns.

User-defined name of any element in ETABS should have less than 11 characters.

After the completion of analysis in ETABS, you will have to generate two data files: one that contains geometry and applied loading information and

other that contains lateral analysis solutions (lateral load cases reactions). To generate a “geometry/loading” file do the following:

• Select the options File/Print Tables/Input...;

• In the above option, select the Check/Uncheck All buttons in the right lower corner of the Printed Input Tables window (see Fig. 1.1-11);

• In the Select Loads tab select the loads that you want to import

• For output, select “print to file”; and,

• Specify a file name and location, where you want the “geometry/loading” file to be saved. Be sure to note the information, since you will need to pass the name and location of this file to the Builder program.

FIGURE 1.1-11

To generate a “lateral reactions” file do the following:

• From ETABS select the File/Print Tables…/Analysis Output. Check all the items, select the loads for import, and check Print to file (see Fig. 1.1-12). Again, remember the name and location of the file.
