SHEARWALLDESIGNTechnical Note

Interactive Shear Wall Design

GeneralInteractive shear wall design and review is a powerful mode that allows quick,on-screen review of design results for a specific pier or spandrel. This modeallows easy modification to design parameters (overwrites) and immediatereview of the new results.

Note that a design must have been run for the interactive design mode to beavailable. To run a design, click the Design menu > Shear Wall Design >Start Design/Check of Structure command.

To enter the interactive design and review mode, right click on a wall pier orspandrel while the design results are displayed . If design results are not cur-rently displayed (and the design has been run), click the Design menu >Shear Wall Design > Interactive Wall Design command and then rightclick a pier or spandrel to enter the interactive design and review mode forthat pier or spandrel.

Note that if both a pier and a spandrel label are assigned to the right-clickedobject, a pop-up box offers the choice to enter the interactive design and re-view mode for the pier or for the spandrel.

The following sections describe the interactive pier design and review and theinteractive spandrel design and review.

Interactive Pier Design and ReviewWhen you right click on a pier for interactive design, the Pier Design form willdisplay. This form provides general information at the top of the box that

identifies and locates the pier. Additionally, the form displays output informa-tion for flexural design, shear design and the boundary element check. TheTechnical Notes provide detailed code-specific descriptions of the types of Output information accessible for interactive design using this form for each

type of design. Access the Technical Notes using the Help menu > Docu-

mentation command.The Pier Design form includes the Combos , Overwrites , Section Top andSection Bot buttons. Note that the Section Top and Section Bot buttons donot appear on the Simplified Section form.

Combos ButtonClick the Combos button to access and allow temporary revisions to the de-sign load combinations considered for the pier. This may be useful, for exam-ple, if you want to see the results for one particular load combination. You cantemporarily change the considered design load combinations to be only theones you are interested in and review the results.

The changes made here to the considered design load combinations are tem-porary. They are not saved when you exit the Pier Design form, whether youclick OK or Cancel to exit it.

Overwrites ButtonClick the Overwrites button to access and allow revisions to the pier over-writes and enable immediate review of the revised design results. If someoverwrites are modified in this mode and the OK buttons in both the Pier De-sign Overwrites form and the Pier Design form are clicked, the changes madeto the overwrites are permanently saved.

Exiting the Pier Design Overwrites form by clicking the OK button temporarilysaves changes. Subsequently exiting the Pier Design form by clicking theCancel button does not save the changes made to the pier overwrites.

To permanently save changes to the overwrites, click the OK button to exitthe Pier Design Overwrites, and then click the OK button to exit the Pier De-sign form.

Section Top and Section Bot ButtonsThese buttons are only visible when designing or checking a pier with a Sec-tion Designer section assigned to it. Clicking these buttons opens Section De-

signer in a locked (read-only) mode, where you can view the Section Designersection assigned to the pier. Clicking the Section Top button allows you toview the section assigned to the top of the pier. Similarly, clicking the Sec-

tion Bot button allows you to view the section assigned to the bottom of the

pier.While in Section Designer, you can review the geometry of the section andthe size and location of the rebar. However, you cannot make any changes tothe section. You can also review the section properties, interaction surfaceand moment curvature curve.

Important note: The interaction surface and the moment curvature curveare displayed for the section as it is defined in Section Designer. Thus, whenyou are designing a pier that is assigned a Section Designer section, the in-teraction surface and moment curvature curve displayed are for the reinforc-ing (ratio) drawn in Section Designer, not the required reinforcing ratio re-

ported in the design output.

When you have finished reviewing the section in Section Designer, close Sec-tion Designer to return to the Pier Design form in the main program.

Interactive Spandrel Design and ReviewNote that a design must have been run for the interactive design mode to beavailable. To run a design, click the Design menu > Shear Wall Design >Start Design/Check of Structure command.

Right click on a spandrel to display the Spandrel Design form for interactivedesign. General information identifying and locating the spandrel is displayedat the top of this form. Output information for both flexural and shear designis also displayed. See the Technical Notes for a description of the types of Output information that is displayed from this form for interactive spandreldesign. Access the Technical Notes using the Help menu > Documentationcommand.

The Combos button and the Overwrites button are also displayed and aredescribed in the next subsections.

Combos Button

Clicking the Combos button accesses and allows temporary revisions to thedesign load combinations considered for the spandrel. This may be useful, forexample, if you want to see the results for one particular load combination.

You can temporarily change the considered design load combinations and

immediately review the results.The changes made here to the considered design load combinations are tem-porary. They are not saved when you exit the Spandrel Design form, whetheryou click OK or Cancel to exit.

Overwrites ButtonClicking the Overwrites button accesses and allows revisions to the spandreloverwrites and enables immediate review of the new design results. If youmodify some overwrites in this mode and exit both the Spandrel DesignOverwrites form and the Spandrel Design form by clicking their respective OKbuttons, the changes to the overwrites are permanently saved.

Exiting the Spandrel Design Overwrites form by clicking the OK button tem-porarily saves changes. Subsequently exiting the Spandrel Design form byclicking the Cancel button does not permanently save changes.

To permanently save the overwrites, click the OK button in the Spandrel De-sign Overwrites form and then click the OK button in the Spandrel Designform.
