The X and Z eccentricities are used in the equivalent lateral force In Model Settings. For more information on this interaction, see the Diaphragms topic. The Mass, Mass Moment of Inertia and Center of MassĪre automatically calculated based on the RISAFloor loads and on the settings To modify these, go to the Beams or Columns spreadsheet in RISAFloor.ĭiaphragms are created in RISA-3D for every floor with a defined diaphragm edge in RISAFloor.Īlthough you cannot delete these diaphragms, you can make them inactive in RISA-3D. Member end releases in the RISA-3D model are controlled by RISAFloor, and cannot be changed in RISA-3D.Members explicitly defined in RISAFloor will have a design list of 'None' in RISA-3D to prevent alternate shapes from being suggested.The unbraced lengths of RISAFloor Lateral members are coordinated with those in the RISA-3D model.These members will be displayed for visual effect only in the model view but will not contribute to the stiffness of the RISA-3D model. RISAFloor "Gravity" members may be viewed in RISA-3D via the Misc Tab of the Model Display Options Dialog.Therefore, these members would only "clutter" the lateral system model in RISA-3D and are subsequently not drawn. These members have been indicated as "gravity-only" members and will not collect any lateral load in the RISA-3D model. Beams, columns, and walls whose function is set to "Gravity" in RISAFloor will NOT be generated in RISA-3D for optimization.

Subsequently, any changes made to RISAFloor generated members in the RISA-3D model will automatically update those same members in RISAFloor model. The "gravity" model in RISAFloor and the "lateral" model in RISA-3D are fully linked.

Walls, and additional loads just as you would in a regular RISA-3D model. Refer to the RISA-3D General Reference Manual and Tutorials for documentation To edit and solve the model. You can add braces, beams, columns,
Once in RISA-3D you will notice that you can use the RISA-3D features The RISA Application Interface will then switch from RISAFloor to that of RISA-3D. In this section of the manual are only available to users who are runningīeams, columns, and walls whose function is set to "Lateral" on the Primary Data Tab of their respective spreadsheets in RISAFloor will automatically be generated in the RISA-3D model when accessed via the Director menu. To access this model, click the Director button on the far right end of the Main Menu and choose RISA-3D.
Systems, another strength is that it can be used to automatically generateĪ model of the lateral force resisting system in RISA-3D. While the primary function of RISAFloor is to create and optimize floor RISAFloor and RISA-3D Integration RISAFloor and RISA-3D Integration
