Step 3: Viewing Generated Hinge Properties (Pushover) This section will demonstrate the process to view generated hinge properties. This step can be skipped if you do not want to view generated hinge properties. 1. Click in the window labeled 3-D View to make sure it is active. Note when the window is active, its title bar will be highlighted. 2. Click the Set Elements button on the main toolbar (or select Set Elements… from the View menu). This displays the Set Elements Dialog box. 3. In this dialog box check the Rel / Hinge box in the Frames area and click the OK button. This will turn the display of hinges on. 4. Note that the hinge at the top of column element 1 is labeled 1H2. (Column element 1 is a lower level column located at X=-24 ft, Y=-24 ft.) We will view the properties for this PMM hinge. Note: In the hinge label 1H2, the 1 indicates the hinge is applied to frame element 1, the H indicates it is a pushover hinge, and the 2 indicates it is the second hinge applied to that frame element. This is an automatic naming convention used by the program for generated hinges. 5. From the Define menu choose Hinge Properties…. This will display the Define Frame Hinge Properties dialog box. 6. Check the Show Generated Props check box. The generated hinge properties now appear in the Defined Hinge props list box. 7. In the All Hinge Props area, click on the hinge labeled 1H2 to highlight it and then click the Modify/Show Property button. This will display the Frame Hinge Property Data dialog box. 8. Note that since this is a default PMM hinge, the P-M2-M3 box is checked, but it is gray and inactive. The program also automatically checks the Axial P, Moment M2 and Moment M3 boxes. All of these boxes are gray and inactive since the user can only view generated hinge properties not change them. 9. Click the Modify/Show For PMM button to display the Frame Hinge Property Data For 1H2 dialog box (see Figure D-2). 10. In this dialog box: • You can not edit any of the values because this is a generated hinge. • The spreadsheet is filled with M/M Y and θ/θ Y values. SAP2000 Web Tutorial 1 94
Figure D-2: Frame Hinge Property Data For Generated Pushover Hinge 1H2 • The default hinge properties are symmetric. • In the scaling area the Yield Rotation is filled in and the Yield Moment is gray and inactive. TheYield Rotation was calculated by the program based on the associated frame section property. The Yield Moment is inactive because this is a PMM hinge and there is no single yield moment, there is a yield (interaction) surface instead. If this were just a moment hinge then there would be a value in the Yield Moment box. • The acceptance criteria are θ/θ Y values. • Click the Define/Show Interaction button to display the Frame Hinge Interaction Surface dialog box. In this dialog box which is mostly inactive because you are viewing a generated hinge property, note: ä The User Definition option is used. ä The Doubly Symmetric About M2 and M3 check box is checked. ä Five curves are used to define the interaction surface.
