| == Common Characteristics ==
| |
| All of these input option begin with the selection of creating a new object, or edit an existing one. The case for material is shown here.
| |
|
| |
| [[Image:BuildingTclViewerInputNewEdit.JPG|link=BuildingTclViewer Input Menu]]
| |
|
| |
| === New ===
| |
| When a new object is to be created, the user must first select the BuildingTcl model used for such object.
| |
|
| |
| [[Image:BuildingTclViewerInputSelectModel.JPG|link=BuildingTclViewer Input Menu]]
| |
|
| |
| The input arguments are dependent on the model selected. However, they are grouped in the following:
| |
| ;Unique Object label : The user specifies this label
| |
| :The default value is the model label. If this label has already been used, the program adds an underscore and an identifying number after this label.
| |
| ;Save : Save the newly-defined object into the library.
| |
|
| |
| === Edit ===
| |
| The user must first select a previously-defined BuildingTcl object.
| |
|
| |
| [[Image:BuildingTclViewerInputEditMaterial.JPG|link=BuildingTclViewer Input Menu]]
| |
|
| |
| The input arguments are dependent on the model used for the object. The user can change the model, however, all input will be lost and default values are restored.
| |
| ;Modify/Save : The new values for the object replace the previously-defined ones, which cannot be restored.
| |
| ;Save As... : A new object with a new label will be saved into the library without affecting the original object.
| |
| : The user can specify a new name for this object. The default will be the name of the original object, with an underscore and a count number after it.
| |
|
| |
|
| |
| === New & Edit ===
| |
| ;Required Arguments : These arguments must be specified by the user.
| |
| ;Optional Arguments : These arguments can be specified by the user. The initial value of these arguments is the default value
| |
|
| |
| '''NOTE: The Required and Optional Arguments text boxes are expanded and contracted when their title (Required Arguments or Optional Arguments) are cliked on by the mouse.'''
| |
|
| |
| === Units ===
| |
| The input for most arguments has optional units. If no units are specified, the program assumes that the input is consistent with the basic units specified at the beginning.
| |
| The user may, however, select the units from a list of possible units. The possible units are specific to each argument.
| |
| Here are three examples:
| |
| *No units specified:
| |
|
| |
| [[Image:BuildingTclViewerInputUnits2.JPG|link=BuildingTclViewer Input Menu]]
| |
| *Units specified manually, or from script:
| |
|
| |
| [[Image:BuildingTclViewerInputUnits1.JPG|link=BuildingTclViewer Input Menu]]
| |
| *Units selected from pull-down menu:
| |
|

| == Material ==
| |
| The following items are found in the Input Menu for a Material:
| |
| *Material Label
| |
| *Material Model Label
| |
| *Input Arguments
| |
| **Required Arguments
| |
| **Optional Arguments
| |
| *Material Test:
| |
| **Test Button -- perform test. A graphic of the stress-strain response is shown after the OpenSees analysis on the material has been done. The material arguments are posted next to this graph.
| |
| **Test-Load Type -- different types of monotonic or cyclic loading patterns can be selected
| |
| **Number of Test Cycles -- the user can select the number of cycles performed at each peak in the load pattern
| |
| **RealTime Option -- when the user checks this option, the analysis data is diplayed real-time. This feature enables a better appreciation of the loading pattern, but slows down the analysis significantly. The real-time display window is closed automatically by the program once the analysis has terminated, so it may be visible for a very short time. The user can stop the analysis at any time using the Stop button in the real-time display window.
| |
| **Material Strain Range -- Maximum strain for test load
| |
| **range of MaterialStrainRange -- change the scale of the range for the MaterialStrainRange

|
| |
| == ElementType ==
| |
| BuildingTcl comes with a set of pre-loaded Default element types for Columns, Beams and Braces.
| |
| This library of element types should be sufficient in defining a model. It is recommended that the user modify these pre-loaded element types and save them under a new name.
| |
|
| |
| In the current release, there are no graphical displays of the element types available.
| |
|
| |
| [[Image:BuildingTclViewerInputDefaultElementTypes.JPG|link=BuildingTclViewer Input Menu]]
| |
|
| |
| For more information, the user should consult the BuildingTcl Manual: [[BuildingTcl -- addElementType]].
| |
|
| |
| Here is an example of the input:
| |
|
| |
| [[Image:BuildingTclViewerInputDefaultElementTypeExample.JPG|link=BuildingTclViewer Input Menu]]
| |
|
| |
| == AnalysisModel ==
| |
| BuildingTcl comes with a set of pre-loaded Default AnalysisModels.
| |
| This library of element types should be sufficient in defining a model. It is recommended that the user modify these pre-loaded AnalysisModela and save them under a new name.
| |
|
| |
| In the current release, there are no graphical displays of the AnalysisModels available.
| |
|
| |
| [[Image:BuildingTclViewerInputDefaultAnalysisModels.JPG|link=BuildingTclViewer Input Menu]]
| |
|
| |
| For more information, the user should consult the BuildingTcl Manual: [[BuildingTcl -- addAnalysisModel]].
| |
|
| |
|
| |
| Here is an example of the input:
| |
|
| |
| [[Image:BuildingTclViewerInputDefaultAnalysisModelExample.JPG|link=BuildingTclViewer Input Menu]]
| |
|
| |
| == Load ==
| |
|
| |
| BuildingTcl comes with a set of pre-loaded Default Loads.
| |
| It is recommended that the user modify these pre-loaded AnalysisModela and save them under a new name.
| |
| The library of loads is not complete with the default Loads alone, though, since no default can be created for a file-input ground motion.
| |
|
| |
| In the current release, there are no graphical displays of the Loads available.
| |
|
| |
| [[Image:BuildingTclViewerInputDefaultLoads.JPG|link=BuildingTclViewer Input Menu]]
| |
|
| |
| For more information, the user should consult the BuildingTcl Manual: [[BuildingTcl -- addLoad]].
| |
|
| |
|
| |
| Here is an example of the input:
| |
|
| |
| [[Image:BuildingTclViewerInputLoadExample.JPG|link=BuildingTclViewer Input Menu]]
| |
|
| |
| === Special Case: GMfilename Selection ===
| |
| For the cases of Uniform ground motion, the user is required to specify the filename(s) and the folder location of the filename(s).
| |
| In BuildingTclViewer, the user selects the location of the input file manually, via windows widget. Once the file is selected, the program automatically uses the folder of the selected file as the GMdirectory.
| |
| For multi-directional input, ALL ground motion files MUST be located in the same directory.
| |
|
| |
| == LoadCombination ==
| |
| A LoadCombination is the final step in defining the loading and analysis. It uses previously-defined Loads and previously-defined AnalysisModels.
| |
| In the current release, there is only one LoadCombinationModel: DefaultLoadCombinationModel. The user is required to select it to maintain consistency with the rest of the input.
| |
|
| |
| In the solution procedure, the program performs the following steps
| |
| 0. Define the Model Nodes and Elements -- (described elsewhere)
| |
| ;Gravity Loads
| |
| 1. For each Gravity Load, one at a time:
| |
| :1a. Calculate nodal masses based on the LoadFactor and the InertialMassFactor defined in the LoadCombination
| |
| :1b. Calculate nodal vertical forces based on the LoadFactor defined in the LoadCombination
| |
| 2. Add up all masses and gravity loads for each node.
| |
| 3. Define OpenSees nodal Masses and Loads in one load case
| |
| 2. Perform Eigen analysis to determine the first three periods of the model. The current release prints this output to the OpenSeesTk window.
| |
| 3. Perform Load-Controlled analysis using the AnalysisModelLabel specified in the LoadCombination.
| |
| ;Lateral Loads
| |
| 4. Define Load and Analysis parameters and perform the analysis for each Lateral-Load case in sequence.
| |
|
| |
|
| |
| ;NOTE: Control of a number of Load and AnlysisModel Arguments has been made available at the LoadCombination level. The values specified at this level supercede the previously-defined ones.
| |
| ;NOTE: In the current release, different types of Lateral Loads cannot be combined in the same LoadCombination:
| |
| :All StaticPushovers must be in the same direction
| |
| :A StaticPushover cannot be followed by a dynamic ground motion.
| |
| ;NOTE: The GravityLoad and LateralLoad boxes can be expanded/contracted by clicking the mouse on "Gravity Loads:" and "Lateral Loads:"
| |
|
| |
|
| |
| The initial input screen for LoadCombinations looks as shown below:
| |
|
| |
| [[Image:BuildingTclViewerInputLoadCombinationInitial.JPG|link=BuildingTclViewer Input Menu]]
| |
|
| |
| While the Required Arguments and Default Arguments input is the same as the other input, the LoadCombination Input has the additional input for Gravity Loads and Lateral Loads.
| |
| To define a load, press the "add Gravity Load" and "add Lateral Load" buttons for each time a load is to be added.
| |
|
| |
| An example of the input is shown below:
